A midsummer’s day surprise

Last week we saw this beautiful and surprising creature, a hummingbird-hawk moth, feeding from the red valerian that grows so profusely in Totnes.

Here are two more photos I managed before it flew away.

The wing span is about 5cm to give some scale.  These day flying moths come into the UK from southern Europe in the summer.

Seeing this insect was all the more surprising as I have recently had several conversations with people about how few moths they see nowadays and that is my experience as well. If you want to read about the general decline of insects in the UK here is an interesting article from the Observer.

Nurdle hunting in west Dorset

Charmouth Beach

You may have never knowingly encountered a nurdle but these small plastic pellets are the raw material of the plastics industry and are ferried around the world in their millions.  About the size of a small pea, nurdles come in many colours and they’re finding their way on to our beaches, killing wildlife and polluting the environment.  I wanted to find out more about these unwelcome intruders, so I joined a nurdle hunt organised by the Charmouth Heritage Coast Centre.

Hunting for nurdles 2
Nurdle hunters getting down to work.

 

Charmouth beach was surprisingly busy that morning but it was half term and, for mid-February, quite warm in the low sunshine.  Many people were walking by the sea, taking advantage of the mild weather, perhaps hoping to find a fossil, but an expectant crowd had also gathered by the steps to the Heritage Coast Centre.  At precisely midday, Sophie Thomas, one of the Centre wardens, walked down the steps together with local volunteer Eden Thomson and gathered us together.   Sophie began by explaining what nurdles were and how they washed up on the beach from the sea.  She emphasised the dangers these plastic pellets pose to wildlife such as birds and fish who mistake them for food.  Each of us was given a pair of disposable gloves, to guard against toxic chemicals contained in the nurdles, and an empty margarine pot for nurdle collecting.  Then off we went, about thirty of us, to hunt among debris washed up on the west bank of the river Char between the two beach car parks.

And what a fine sight we were! Young and old, locals and visitors, families and children, sitting or lying on the ground, enthusiastically scouring the debris for the plastic pellets.  It was a fascinating event, although we did get some funny looks.  Everyone found pellets in large numbers, not just on the surface but also buried a few centimetres down showing how pervasive they are.  Some were smooth, grey and cylindrical and a few were lentil shaped, white, yellow or green.  The vast majority, however, were bright blue cylindrical pellets, about 5mm in size, with fine ridges. The grand total for the group was 6650 pellets collected in 90 mins from this small section of beach, highlighting the extent of the contamination.

What do we know about nurdles and how they get into the sea to wash up on our beaches? These small plastic pellets are made from oil or natural gas to provide an easily transportable raw material for use in plastics factories all around the world.  Most of the plastic products that now dominate our lives are made from nurdles and huge numbers of the pellets are transported by ship, so there is always the potential for spills.  In October 2017, two containers of nurdles fell from a ship in the port of Durban leading to massive nurdle pollution along more than 1000km of beaches.    Closer to home, the storm-damaged container ship, Napoli was beached off Branscombe early in 2007 leading to hundreds of containers breaking free.  Two containers were filled with nurdles which washed up along many local beaches. These environmental disasters have been likened to oil spills, only worse as the nurdles do not break down.

Nurdles can also end up in the sea through careless handling at plastics factories.  The environmental charity, Surfers Against Sewage, visited several plastics companies in Cornwall and found nurdles littered around the sites.  These will inevitably be blown or washed into drains and into the sea.  Another kind of plastic pellet, wrinkly or ridged, has been found in large numbers on beaches in Cornwall by Rame Peninsula Beach Care.  These are biobeads, easily confused with nurdles but with a completely different purpose.  Some sewage works use biobeads as part of the wastewater treatment process and the pellets get into the sea through careless handling by water companies.

Why should we be concerned about nurdles and biobeads?  They are a totally unnecessary form of pollution in our seas and on our beaches and their presence shows a lack of respect for the environment.  They are now found all over the world wherever the sea meets the land: on beaches in industrialised countries or on isolated, sparsely populated islands.   Not only do they pollute our beaches, they are eaten by seabirds and fish who mistake them for food.  Once consumed, they block the digestive tract, lodge in the windpipe or fill the stomach leading to malnutrition and starvation.   For example, analysis of dead puffins on the Isle of May in Scotland, home to one of the UK’s largest breeding populations of these birds, showed they had consumed nurdles alongside their usual diet of sand eels.

Nurdles are also a source of toxic chemicals that may exacerbate their physical effects.  Freshly spilt nurdles may release chemicals such as plasticisers used in their manufacture.  Nurdles that have been in the sea longer attract toxic chemicals such as PCBs and DDTs.  These substances may have a toxic effect on seabirds and fish that consume them and have unknown effects on humans who encounter them on beaches.

What can we do about the nurdle problem? Industry needs to improve handling procedures and make sure nurdle spills are cleared completely.  Operation Clean Sweep is a plastics industry programme aimed at eliminating pellet losses but, as yet, it is only voluntary. In the longer term, we need to reduce our dependence on plastics, especially single use plastics.

Nurdle hunting can also help by raising awareness and by reducing pellet numbers in the environment.  As Sophie Thomas said to me “A nurdle collected is a nurdle out of the sea”.  Occasionally, it may be possible to infer the source of pellets based on their appearance and properties.  For example, the pellets found at Charmouth are unusual compared to those I have seen on other beaches.  Although some at Charmouth are true nurdles, the majority are the bright blue cylindrical type with fine ridges, more typical of a biobead.  If these are indeed biobeads, how are they getting on to Charmouth beach?

This article appeared in the May edition of the Marshwood Vale Magazine.

It was also a pleasure to meet Sarah West and her husband John that day.  Sarah is a blogging friend and she and John had also joined the nurdle hunt.  Sarah writes the blog “Down by the Sea” and has recently been heavily involved in organising the Bridport Green Fortnight.

I returned to Charmouth Beach on May 1st and picked up these in about five minutes on the east side of the river Char. The bright blue pellets predominate as before, note the fine ridges characteristic of biobeads. The grey pellets are mostly smooth, characteristic of a pre-production plastic pellet or nurdle. The lentil-shaped, pale pellets are also nurdles, commonly referred to as “mermaids tears”; they acquire colour if they stay in the sea a long time. The yellow and the one pale blue pellet are nurdles

An amazing natural phenomenon goes unnoticed

Brixham view

After so many cool, damp and grey days, spring arrived in a rush in the third week of April. Temperatures soared by nearly ten degrees and the sun shone strongly from a virtually cloud-free sky, filling the air with an unexpected brightness, at least for a few days. The sudden change in the weather demanded that I get outside so I drove the short distance to the fishing port of Brixham, parking on the clifftop road on the eastern edge of the town. A steep stone stairway took me down the hillside past curious, deserted, rectangular buildings and wide sweeps of concrete enclosed by thick scrub echoing with birdsong. These are remnants of the Brixham Battery, built in 1940 to guard Torbay against a German invasion, now Grade 2 listed and an informal, unplanned nature reserve. Dandelions and cowslips were dotted about grassy areas and fleshy-leaved green alkanet with its grey-blue flowers provided a contrasting colour. The stairway continued downwards among trees until I was just above the sea where I joined the coast path.

This section of the coast path is enclosed by low scrub and, at this time of year, blackthorn dominates, its branches covered with a snow of small flowers, creating a curtain of white with occasional glimpses of the blue sea. In the bright sunshine, the delicate white petals were almost transparent below a confused mass of yellow-tipped stamens. Eventually, this enclosed path gave on to an open, grassy area roughly the size of a football pitch, overlooking the water of Torbay and backed by thick trees creating a sense of seclusion. Wooden benches positioned along the sea side were popular, occupied by people wearing sun hats and enjoying the spectacular view.  The full panorama of Torbay was spread out ahead like an enticing display in a travel brochure: the red cliffs, the white seafront buildings, the pine trees, the big wheel and, in the foreground, the Brixham breakwater with its white lighthouse. The sea was a bright, slightly greenish blue textured with patches of silvery sheen  and pleasure boats shuttled across the water to and from Torquay.  It was a holiday scene and felt almost Mediterranean.

Amongst all this human activity, no one seemed to be paying any attention to the many mini-volcanoes of crumbly soil partly concealed beneath the rough grass or to the many bees moving about the area just above the grass. Everywhere I looked there were bees flying about, backwards and forwards, swinging from side to side, as if they were trying to find something; a few were walking about on the red soil. There must have been thousands of bees, an amazing natural phenomenon and very exciting to watch. When I looked carefully, I saw that they were mostly black but with distinctive bands of pale hair. These are Ashy Mining Bees (Andrena cineraria), one of our more common solitary bees, and the soil volcanoes in the ground are their nests.

While I was taking in the scene, a couple arrived, both carrying plastic bags. He was in his sixties with long white hair roughly corralled into a pony tail. She was in her late fifties with copious dark hair. They threw down a blanket into the middle of the grassy area, stripped down to their underwear, cracked open some cans and proceeded to sunbathe. Like the other people, they didn’t notice the bees swirling about the grass around them and I wondered how they might react if they encountered the insects. Luckily for them, only the females of these kinds of mining bees possess a sting and they use it only when threatened.

I wanted to take some photos of the bees but, wishing to avoid any misunderstandings as I waved my camera about, I moved to the other end of the grassy area, passing a small turf-roofed building that used to contain the searchlight for the wartime Battery. I found an unoccupied bench, sat down, and providing I was still, the bees resumed their incessant movement around me. The bench turned out to be a front-row seat as, on several occasions, I saw one bee rush at another and the two struggled for a while on the ground. Two or three others tried to join in and it all got a bit confused and messy for a while. Eventually, however, only two were left coupled together, end to end. They stayed like this for a few minutes before separating and flying off. I presumed they were mating but it seemed rather sedate compared to the frantic copulatory behaviour of some solitary bees.

Photographing the flying bees is difficult, but for the short time they were occupied in mating they were relatively still, making it easier. My photographs showed that the honeybee-sized females have shiny black abdomens with a blue sheen in some lights. Two thick, furry bands of grey-white hair line the front and back of the thorax and the face is white-haired with black antennae. The slimmer and smaller males also have black abdomens but differ from the females in having white hairs on the sides of the thorax and thick tufts of white hair on the face. With their pale hairs and contrasting dark abdomens, Ashy Mining Bees are one of the most distinctive and beautiful species of mining bee in the UK.

Despite all this excitement on the ground, I kept an occasional watch on the sea and got quite excited when I saw a shiny black head emerge from the water. This was one of the local colony of grey seals swimming towards Fishcombe Cove. The water was so clear and calm that the seal’s huge body was clearly visible as it passed.

When I had finished, I walked back past the lush banks of three cornered leek that grow along the low cliff edge. I saw male Ashy Mining bees nectaring from the delicate white-belled flowers. Further on, I stopped to look at the blackthorn flowers. Here there were more Ashy Mining Bees foraging together with one very different bee with a shock of orange-brown hair on the thorax and a largely black abdomen tipped with orange-red hair. I later identified this as an Orange-tailed Mining Bee (Andrena haemorrhoa). With all this insect interest, there should be a good crop of sloes on the blackthorn here in the autumn.

Death and destruction at Dawlish Warren

As we stepped off the train at Dawlish Warren station, we had our first glimpse of the river Exe, its waters a sparkling pale blue in the bright sunshine.  The weather was a welcome change after so many cold and snowy days but, during our short journey from Totnes, we had passed bright ridges of snow still piled against field hedges and, in low lying places, large lakes of standing water from snow melt.  Perhaps the weather was giving us a gentle reminder of its power to disrupt life.

We hadn’t intended to visit Dawlish Warren again so soon (see here for a description of our previous visit) but we wanted to get out for a walk and, hearing that some country roads were still snow-blocked, we chose somewhere easily accessible.  We also wondered how the recent extreme weather might have affected this beautiful sand spit.

The view from the promenade quickly told us part of the answer.  Sand was piled up on the retaining wall that slopes to the beach and, along the promenade, some of the benches were partly submerged in sand as if caught by a pale brown snow storm.  On the beach, huge quantities of wooden debris lay in random heaps, along with some very large plastic items; it will be a mammoth task to clear this.  A closer look showed that the debris was a mixture of wood and reeds along with bits and pieces of plastic and many industrial plastic pellets (mostly grey nurdles).  I don’t want to go on too much about these industrial pellets, I’ve written about them several times already, but we found them littering all the beaches at the Warren to a greater or lesser extent.  Near the promenade there must have been thousands.

As we were picking up a few of the pellets, a woman asked Hazel what she was doing.  After an explanation, the woman said:

“I thought you were picking up driftwood,” and after Hazel had shown her some pellets the woman continued “still they might be very nice for decorating a mirror.”

 

We then walked around the Dawlish Warren sand spit following the route I outlined in a previous post, which also gives some background information about this nature reserve.

The central area of the Warren was partially flooded but still passable.  No spring flowers were to be seen yet but small birds were performing florid mating displays while a group of black corvids sat judgementally in a nearby tree.  Vegetation along paths over the dunes was seemingly spray-painted with a coat of rough sand, probably a result of the blizzard sucking up material from the beach.   Near the bird hide, I disturbed a large flock of Brent geese feeding on the golf course.  These imposing birds took off as a group and circled low over us before moving to a quieter spot.

Warren Point at the end of the sand spit was as mysterious and beautiful as always, its pale marram grass covering glowing in the sunshine. A small flock of linnets, the males with their pink bibs standing out, fidgeted in the branches of a low bush.   A skylark rose from the ground, wings flapping frantically as it hovered in mid-air, singing, turning a tune over and over, changing it each time.  Then, without warning, it stopped flapping and deftly descended back to the ground with subtle, steadying wing movements.

The story on the beaches bordering Warren Point was less uplifting.  There was a slew of debris along the strandline, mostly wood and reeds but also many dead birds. We saw at least twenty casualties, mostly lapwings, identified by their largely black colouring combined with russet brown and white undersides.  During the storm there had been a mass movement of these birds across the Warren and a proportion didn’t survive.  We also saw one or two golden plovers with their exquisite pale brown and white herringbone patterns.  On the beach facing up the Exe, the low sand cliffs at the back of the beach had been damaged by high water and when we rounded the point to walk back, there were more signs of storm damage.  Areas of marram grass had been torn out and reddish soil had been deposited on the edge of the remaining marram grass.

The most significant damage, however, had occurred to the taller sand cliffs that abut the groynes on the sea-facing beach.  Sand had been washed away from the back of the groynes and several metres of sand cliff removed exposing, in some places, the old sea defences.  Some of the new fences built on the reinforced dune ridge had been torn out and now lay on the ground in casual heaps or hanging in mid-air, still partly attached.  The groynes themselves seemed to be intact but plastic notices attached to them lay in pieces among the other debris.  In a powerful demonstration of the scale of the storm and the water level reached, small pieces of wood and more plastic pellets lay along the wooden planks of the groynes and on top of the main support posts nearly a metre above the sand.

Despite all this, the Warren itself is intact and ready for the bloom of spring flowers. The scale of the damage to the new sea defences was shocking and a salutary reminder of the power of the sea, but at least the defences did hold.  Elsewhere in south Devon, the coast road linking Torcross and Slapton was almost completely washed away.  As in 2014, when the Dawlish railway line was destroyed, this year’s damage was the result of a combination of high winds and very high tides, perhaps combined with increased sea level.

As we waited at the station for our homeward train, I noticed willow trees by the platform with many plump, pussy willow catkins.  A medium sized buff-tailed bumblebee arrived to collect pollen from the lemon-yellow male flowers.

We visited Dawlish Warren on March 6th 2018

The elemental and the mysterious at Dawlish Warren

I wasn’t sure what to expect today. Major engineering work had been carried out at Dawlish Warren over the past year to stabilise the beaches and dunes and this was our first visit since the project had been completed. I hoped the area hadn’t been changed too much as it’s a special place.

Dawlish Warren is a massive sand spit that extends north-eastwards for about 2km across the mouth of the River Exe from its western bank. It reaches out like a giant hand towards the town of Exmouth but fails to make contact, leaving a narrow channel where tides and the waters of the Exe flow in vast amounts each day. The sand spit is about 500m wide but incomplete; a huge bite has been taken out of the inner side creating the inland bay, leaving the tip of the spit, Warren Point, attached by a thin strip of dunes. Some of the recent stabilisation work was aimed at strengthening this dune strip against future increases in sea level. Much of the Warren is now a nature reserve with several rare habitats including vegetated dunes, mud flats and salt marsh and has been designated as a Site of Special Scientific Interest.

The Warren was once used for breeding rabbits for food, hence the name, but with the arrival of the railway, it became a popular holiday resort. It now also has a golf course, fun fair, shops, cafes and a pub although these are concentrated at the western end and do not detract appreciably from the nature reserve.

Despite heavy overnight rain, the day was dry, and warm for the time of year (11 degrees) but feeling cooler in the stiff sea breeze. Layers of dark cloud dominated the sky but occasional linear shafts of sunlight broke through towards the steel-grey sea. There were clear views from the promenade along the outer sea-facing beach with its many groynes and across the water to Orcombe point, the start of the East Devon/Dorset Jurassic Coast.

We left the promenade via a boardwalk descending to the central, low-lying part of the reserve, once a tidal lake but long since filled in. Today the area was puddle-strewn and barren; later in the year, it will be a colourful mosaic of wild flowers. A large pond with wildfowl lay behind a tree screen where an exquisitely pink male bullfinch showed for a while. On the water, two swans performed like synchronised swimmers.

A sandy track led us up to the marram grass-fringed path along the crest of the outer dunes with views over the golf course and inner bay to the north and across the outer sandy beach and sea to the south. A large flock of Brent Geese were feeding on one of the greens, no doubt to the irritation of the golfers. Dropping down to the inner bay we walked along the stony foreshore, finding it littered with large amounts of debris, mostly wood and reeds but also industrial pellets and shards of plastic.

On one side of the inner bay there is a large bird hide that looks across mud flats and salt marsh at low tide. Huge numbers of waders can be seen here. Yellow gorse sparkled near the hide together with several small stands of flowering ragwort; fuzzy, lime green lichen coated some bushes. From the hide, we watched ghostly black cormorants on a mud bank spreading their wings to dry and saw hundreds of oystercatchers huddled together, the colours of their plumage merging into discrete layers of black and white. A little egret flew across displaying its yellow feet and a curlew probed the mud with its long curving beak.

From the inner bay we accessed Warren Point and the soft sandy beach that leads around the tip of the sand spit. At the back of the beach there were dunes clad with marram grass, a subtle mixture of green and yellowish-brown spikes. This part of the Warren is both strangely beautiful and unsettling and as we circled the Point, we were conscious of the vast amounts of water passing at the foot of the sloping beach and the apparent proximity of Exmouth just across this turbulent channel. Again, there were huge amounts of debris on the beach, wood and reeds predominantly but mixed with plastic including more industrial pellets. On the inner beach, we also saw as many as eight green tennis balls, many plastic bottles, several golf tees and many fresh green leaves. I presume this waste had come down the Exe propelled by the heavy rain that had fallen inland over the past few days. Once we had rounded the Point and started walking back along the outer beach, the nature of the debris changed and we saw mainly plastic rope and twine, probably fishing-related.

By now it was mid-afternoon and the low tide gave us the chance to walk below the end of the newly reinstated groynes that stalk, triffid-like, across the wide sandy beach. The sea was calm but the gentle waves were enough to satisfy a lone, silhouetted surfer. Then, for a few minutes, the low sun broke through the layers of grey cloud, casting an intense yellow light across the dunes at the back of the beach, creating a mysterious, unnatural landscape where, surrounded by pink sand, the marram grass had turned to gold. At the same time, the western view was filled with an intense white light, bleaching grey out of the cloud and sprinkling silver across the sea.

Eventually, we reached the commercial part of the Warren where the mystery might have ended, but there was one final treat in store: a queen buff-tailed bumblebee as large as my thumb, collecting pollen from purple Hebe, presumably to stock her nest.

My concerns about the effects of the engineering work turned out to be mostly unfounded. Only one part of the Warren is visibly different, the narrow dune strip which is now topped with bare sand. The area has, however, been planted with marram grass which will take over in time. Overall, Dawlish Warren remains a special, elemental place.

The featured image shows the outer beach and groynes viewed from the dune strip, with, in the distance, Orcombe Point and the start of the East Devon/Dorset Jurassic Coast .

A country walk, a clean beach and the fallacy of perpetual growth

The Christmas weather in south Devon was stormy and very wet so when we woke on December 27th to bright sunshine and clear, pale blue skies we had to get out for a walk.   We chose one combining countryside and sea, one we often walk after heavy rain as it mostly follows minor roads or paved paths.

We started at Townstal, a suburb on the edge of Dartmouth.  Townstal is noted for its leisure centre and two supermarkets but it does provide easy parking and quick access to open countryside.  Our route headed gradually southwards towards the sea along narrow roads edged by high grassy banks.   Volleys of gulls and crows rose from adjacent fields and the low sunshine created strongly contrasting areas of light and dark on the deep valleys and rolling countryside, emphasising even the slightest undulation.

Some steep ups and downs took us to Venn Cross where we turned to descend along the Blackpool Valley with its spirited stream, growing ever fuller as it gathered water from springs or from the sodden fields.  This part of the walk is tree lined and the minor road is cut into the hillside well above the stream.  Several former water mills are dotted along the valley; they are now rather grand private houses but one has installed a turbine to harness the power of the water once again.

At this time of year, the trees are dark latticeworks of bare branches but pale brown immature catkins were showing well on some of the trees, readying themselves for the spring.  Patches of winter heliotrope spread along verges enclosing the ground with their fleshy, green, heart-shaped leaves.  Purple and white lollipop flowers struck through the leaves, broadcasting their characteristic almond odour.

Eventually, we reached Blackpool Sands, a popular shingle beach and café, surrounded by pine trees and sheltered by steeply rising hills.    The low winter sun created strongly contrasting colours: the yellowish- brown shingle, the fringe of frothy white waves, the sea a rich dark blue tinged with turquoise highlights, and there were clear views across the bay to Start Point with its lighthouse.   Near the café, a hardy group of swimmers were struggling on their wet suits in readiness for a dip.  They passed me as they ventured in to the sea accompanied by audible yelps and shrieks.

I was keen to have a look at the shingle beach for two reasons.  There had been a very successful beach clean four days previously organised by Amanda Keetley of Less Plastic.  We hadn’t been able to be there owing to family commitments but there had also been storms since then and I wondered how much more plastic had washed up.  I didn’t find any, the beach was still clean which should have been good news.

To be honest, however, I was feeling disheartened about efforts to reduce the load of plastic in our seas after reading two articles in the Guardian over the Christmas period.  It seems that the US, along with financial support from Saudi Arabia, is planning a huge increase in plastic production, the driver being cheap shale gas.  If we are to reduce the amount of plastic in our seas we need to reduce the amount in circulation and this new plan runs directly counter to this.

Here are links to the two articles:

$180 billion investment in plastic factories feeds global packaging binge

World’s largest plastics plant rings alarm bells on Texas coast

I am not sure how this can be stopped but I am convinced that the drive for perpetual economic growth, espoused thoughtlessly by so many of our politicians, is ultimately very damaging for our planet.

If we love our beaches and our seas, we have to talk about plastic

Towards the end of October, I spent a day at Cogden Beach, just east of Burton Bradstock in west Dorset.   It’s a beautiful, natural spot, a rich concoction of sea, sky and shingle where wildlife prospers despite the sometimes harsh conditions.  It’s becoming increasingly difficult, however, to ignore the scatter of plastic pollution on the beach and the potential effects of this manmade material on marine life.

It felt unseasonably warm as I walked downhill from the car park, more like a late summer’s day, although the blood-red rose hips and smoky-black sloes decorating the leafless scrub spoke of a different season. The vast shingle bank of Chesil Beach dominated the long view, a yellowish-brown convexity edged with white waves sweeping eastwards towards a mistily mysterious Isle of Portland.  The sea was calm and a steely grey except where the low sun’s rays highlighted individual wavelets whose reflections merged in to a broad, silvery band of light.

When I reached the shingle bank I found traces of the special beach plants that grow so profusely here in spring and summer.  Well weathered, blue-green and brownish-grey leaves were all that remained of the sea kale that dominates in May whereas, beneath the brown remnants of this season’s vegetation, fresh glaucous leaves were showing from the yellow horned-poppies.  Small flocks of starlings skittered about puddles at the back of the beach like children in a school playground and, in a low sandy cliff, I was surprised to find bees busily filling nests.  These were ivy bees (Colletes hederae), the last of our solitary bees to emerge, the females collecting chrome-yellow pollen from nearby clumps of flowering ivy.  To the west, there were spectacular views of Burton Bradstock’s yellow cliffs and the distinctive flat top of Golden Cap.

It seemed like the perfect natural spot.  But was it?  Almost all the clumps of beach plants contained plastic waste including pieces of plastic wrap, colourful plastic rope or plastic fishing line.  On the shingle between the clumps, I saw the occasional plastic drink bottle, some were intact, some in pieces.   The prominent strandline about half way up the beach contained dark, dry seaweed and small pieces of wood mixed liberally with shards of plastic as though objects had shattered in their continual buffeting by the sea.  Plastic drink bottles or their fragments also appeared at regular intervals along the strandline.  This beach is no longer a completely natural, wild place, it has been contaminated by our throwaway plastic culture.   Perhaps the most poignant symbol of this tension was a chunk of expanded polystyrene covered with pale grey goose barnacles.

Plastic is, of course, both versatile and cheap.  It has transformed our lives but its very ubiquity and ease of use means that we don’t value it enough.  Think how much you throw away each week: plastic wrap or bags from supermarket produce, drink containers and lids, plastic trays, pots and so on.  We have embraced a “disposable” lifestyle where about half of the plastic we produce is used once and thrown away.   Some countries manage to recycle or energy-recover a large proportion of their plastic waste but the UK is not one of them.  In this country, more than 60% of plastic waste ends up in landfill where it does not break down and is effectively lost.  We are squandering resources and energy on a massive scale, an appalling indictment of our way of life.

But what about the plastic waste I found on Cogden Beach, how does it get there?  It comes from the sea and is left behind by the retreating tide.  We have turned our oceans into a “plastic soup” composed of plastic bottles and bags, plastic fragments formed by breakdown of these larger items, also microplastics (5 mm or less in size) such as industrial pellets, small fragments and very small fibres from clothing or from car tyres.  This is a huge global problem and shows no sign of abating.  A staggering 12 million tons of plastic waste enters the oceans each year. All countries contribute but a large proportion comes from several in the Far East with poor waste management systems.

The consequences for marine wildlife are alarming.  Consider, for example, the Northern Fulmar, a bird that forages exclusively at sea.  A study in the North Atlantic showed that 91% of dead Fulmars found on beaches had plastic in their gut, having mistaken the plastic for food, reducing their ability to feed and sometimes damaging their digestive tract.  At the other end of the food chain, zooplankton have been shown to ingest tiny microplastic fragments that may end up in fish and perhaps in humans.  Plastic fragments also attract toxic chemicals that may affect the creatures consuming them.  Our throwaway lifestyle is disturbing the entire global marine ecosystem. The problem is just as serious as climate change.

What can be done?  First, we must reduce the amount of plastic in circulation by moving away from single-use items such as plastic bottles, takeaway cups, plastic cutlery, plastic wrap and plastic packaging.  The introduction of the 5p charge on plastic bags led to an 85% reduction in use, so a levy on single-use takeaway cups and plastic cutlery may also be effective.    Second, we need to encourage a “circular economy” where as much plastic as possible is recovered and recycled and none goes to landfill.  A deposit return scheme for plastic drink bottles would increase recovery but greater recycling of other plastic containers must also be achieved.   It is encouraging that some government ministers are now talking about the problems of plastic waste, but their words must be translated into actions.

Individual decisions can also bring about change.  We can refuse to use plastic cutlery.  We can choose to drink only from reusable cups.  We can use and reuse our own shopping bag.  We can recycle all plastic bottles and containers. We can pressurise local businesses to reduce plastic waste.  We can participate in beach cleans.  If we love our beaches and our seas we must do this.
