Endangered Sea Life in the UK – How Are We Progressing?

The cold sea temperatures around the United Kingdom make it the perfect home for a variety of marine creatures. The waters surrounding our island are teeming with amphibians, reptiles and fish but there’s one crushing concern: many of these creatures are classed as endangered and some are even on the verge of extinction.

It’s a sad fact, but due to unsustainable fishing and increased water pollution over the last 40 years our marine wildlife has dwindled. A series of rehabilitation programmes aimed at making our seas more sustainable, and the introduction of protective measures has helped to claw back some of our marine life from the brink of extinction. But exactly what progress is being made?

Protecting our seas

Growing awareness about the state of UK seas gained momentum throughout the 1970s, and by 1983 the Marine Conservation Society had been registered. A number of initiatives have been launched throughout the last 35 years to promote marine life and ensure that our oceans are protected from the five challenges that The Wildlife Trusts claims are currently facing our seas:

  1. There are not enough protected areas at sea
  2. Discarding issues in the fishing trade
  3. Lack of planning of competing interests
  4. Severe pollution
  5. Human behaviour

The introduction of Marine Protected Areas (MPAs) in the UK means damage limitation is being controlled in specific environments. These areas form a chain around our coastline protecting a wide range of marine wildlife. WWF is currently championing The UK SEAS Project which is looking to develop MPAs to improve their management and effectiveness. While we’re yet to see long-term benefits, it’s believed these segregated areas will protect endangered sea life and provide pockets of the environment where fish and marine life can flourish.

The International Union for Conservation of Nature’s Red List of Threatened Species lists the Atlantic Halibut and Atlantic Bluefin Tuna as endangered, while the Atlantic Cod and Basking Shark are vulnerable. Basking sharks are now protected in UK waters, and data suggests their population in the UK may be beginning to recover. Although only a summer visitor to our waters (typically during May-October) basking sharks tend to live a long life in the wild, and Cornwall is often tipped as one of the best places to catch a glimpse of one.

Now classed as a vulnerable species, Atlantic Cod has found itself on this list as a result of overfishing. Western Europe accounts for an estimated 70-80% of the world cod market, with the UK being Europe’s largest importer and consumer. Fisheries have become more savvy when it comes to catching cod, and unregulated fishing remains a constant threat to sea levels. Creating sustainable market incentives and ensuring the correct management of fisheries are the next steps to promote stock in our seas and decrease the amount of endangered sea life.

It’s due to discarding issues in the aforementioned fishing trade that we are seeing a reduction in fish stocks in our seas. With demand for fish constantly increasing, overfishing has caused a detrimental effect on many forms of marine life. In 2013 a reform of the EU’s Common Fisheries Policy saw a commitment to end overfishing and a landmark ban on discards, the practice of throwing unwanted catch back into the sea. By next year the practice of discarding should be totally phased out, but is it enough to allow us to regain control of our seas?

Of course, fishing isn’t the only industry that has contributed to the negative effects on our marine wildlife. Offshore oil rigs and wind farms put huge pressure on UK seas, encroaching on fragile seabeds and disturbing subsequent wildlife. There is a large requirement for well thought out plans for our seas, so that we’re able to provide space for our marine life to thrive and recover from the detrimental effects of the past few decades. This doesn’t mean banning such important industries, but working hard to create a solution in which they can co-exist with our environmental wildlife.

The ban on plastics

It’s a well known fact that our seas are now heavily polluted, and one of the biggest threats of the 21st century is the amount of plastics that are finding their way into our oceans. Greenpeace UK estimates that around 12.7 million tonnes of plastic ends up in our oceans every year. This includes everything from plastic bottles to bags and microbeads, and equates to a truck load of rubbish a minute.

Huge steps have been taken on the journey to eliminate plastics, supermarkets now charge for carrier bags and plastic straws are steadily being withdrawn from many establishments throughout the country. Some towns have even been granted ‘plastic free’ status by Surfers Against Sewage – this includes Newquay, which is now officially part of a ‘Plastic Free Community’ due to the number of residents opting to use less plastic and volunteering themselves for beach cleans.

Plastic still remains a high threat to UK marine life, larger wildlife (including some forms of birds) can become entangled in plastic bags and other debris, there is also a significant issue with the consumption of plastics within the marine life community. Turtles in particular cannot distinguish between jellyfish and plastic bags. While the former is part of their everyday diet, the latter causes internal blockages and usually results in the death of the animal. Concerning results emerged from a Plymouth University study, which established that a third of fish caught off the UK were found to contain plastic – this included cod, haddock, mackerel and shellfish.

It’s a crushing fact, but in the 21st century the largest threat to our seas comes from humanity. The number of initiatives setup to help preserve our oceans and the wildlife within them has no doubt helped to save endangered sea life species from extinction. However, it’s our poor treatment of our seas, and the extent to which we have polluted them, that has had a direct impact on the dwindling numbers of sea life off UK shores. There has been an increase in the number of some protected species, such as the Basking Shark, and it is hoped that the recently introduced measures will promote the continuing growth of sea life in our oceans.
