Oceans supply half the oxygen we breathe and provide food and livelihoods for more than a billion people. They are also home to a wondrous array of wildlife. And while oceans may seem endless and indestructible, the truth is that our oceans are in crisis. We’ve already lost half our coral reefs and mangroves − some of the most productive habitats on Earth. We’ve pushed many crucial fish stocks to the point of collapse, threatening people’s livelihoods and food security – and harming other species including seabirds, turtles and dolphins. The loss of reefs, mangroves and seagrass beds leaves coastal communities vulnerable to erosion, storm damage and food shortages. Pollution – from plastics to oil spills to agrochemicals – also harms nature and contaminates food chains. And climate change is making the ocean hotter and more acidic, which could spell disaster for coral reefs, polar regions and the rich variety of life they support. Right now, governments, businesses, and NGOs are meeting in Oslo for the 2019 Our Ocean Conference to discuss how we can secure the future of oceans. Rest assured that we will be calling for urgent action – but you too can play your part. With world leaders scheduled to make critical decisions on nature, climate and development in the coming year, 2020 offers a momentous opportunity to secure a sustainable future for oceans and other natural places, together with the people and wildlife who depend on them. Join the many people from around the world who are calling on leaders to take action in 2020. You can also add your voice to almost 1.5 million people calling on world leaders to take action against the ocean plastic pollution crisis that’s harming both people and wildlife.
