Our oceans are in crisis.
A recent report shows more than half of the planet Earth's marine species may stand on the brink of extinction by 2100. Find out how ZSL is helping, and how you can too.
Human activity has a serious impact on marine life, and the consequences are becoming clearer every day. Overfishing, pollution and climate change have triggered major declines in our marine life. This does not only pose a threat to our environment, but it is also a threat to our food security – the Scombridae family of fish, including tuna and mackerel, has seen a global population decline of 74%.
Other species in decline include:
- Sharks and rays: 25% of shark, rays and skates are now threatened with local extinction
- Fish that are harvested: 50% reduction in population size globally between 1970 and 2010
- Coral reefs: Coral reef cover – has decreased by more than 50% over the last 30 years.
What you can do
- According to a recent study, globally 13 million tonnes of plastic waste enters our ocean every year, threatening species from turtles to seabirds. Reduce your plastic use, and recycle what you do use.
- If you consume seafood, make sure it is sustainably sourced. You can use online tools such as fishonline.org.
- The more data we have on what’s living in our oceans, the easier it is to conserve it. Take part in a citizen science programme, such as an eel survey or look for other ways to get involved. You can also report Thames marine mammal sightings to our map, and report sightings of seahorses and angel sharks.
- Marine Protected Areas have been proven to be an effective way for us to reverse the terrible damage we’ve done to our oceans. Support the creation of MPAs in the UK, the UK Overseas Territories and abroad.
- Help with a beach clean near you – you can find opportunities on the Marine Conservation Society website.
- Share your determination to protect marine life, and your examples of success stories, and encourage others to do so too. Use hashtag #OceanOptimism and #StateoftheOceans.
What ZSL is doing
We’re running conservation programmes around the world to try and protect marine species, including:
- UK and Europe - we're protecting the Critically Endangered angel shark in the Canary Islands, and monitoring eels, seals and fish in the Thames with the help of citizen scientists
- Indian Ocean – we were an instrumental partner in the establishment of the largest no-take marine reserve around the Indian ocean. Our research is helping management of this reserve and understanding of how well it protects mobile species like tuna, sharks and seabirds.
- Project Ocean – ZSL is working with Selfridges to establish new marine reserves, encourage people to avoid eating endangered fish and tackle the problem of plastic in the ocean. Start helping by using a refillable water bottle today.
- Net-Works – ZSL is a key partner in this innovative project which sees local communities collecting discarded fishing nets, a major threat to marine life, from the ocean and selling it into the supply chain to be made into carpet tiles.
- Mangroves – the latest figures show a 20% loss in mangrove cover between 1980 and 2005. We’re working to protect and restore mangroves in the Philippines. Over a four year period, close to 100,000 mangroves were planted and we are now integrating mangroves into Marine Protected Areas.
