Oceans cover well over two-thirds of the planet's surface and are home to a world where at least a million known species of plants and animals depend on each other for survival. Small marine organisms are food for larval and juvenile fish that in turn are consumed by larger fish that eventually fall victim to top predators. Humans have relied on this entire food chain for sustenance for a long time.

But now more than 85 percent of the world's fisheries have been pushed to or beyond their biological limits. Pollution, poorly planned development, and the effects of climate change have also contributed to the degradation of the underwater environment.

WWF believes that conserving marine habitats and promoting sustainable fishing methods are as important to people as they are to wildlife. We support marine conservation in places such as the Coral Triangle, the Arctic, and Coastal East Africa and also on the high seas. We help to protect a long list of species that are of crucial importance to the entire marine ecosystem and those communities that depend on it for their livelihoods and food security.

Preserving healthy fish populations and securing sustainable fisheries is only possible by working collaboratively with the private sector. WWF works with the companies along the entire value chain, from the world’s oceans to your plate, to protect our seafood supply and to make sure that the interconnected network of underwater species will thrive into the future.
