Our oceans are vast, but they are not immune to human influence. We have already altered or destroyed many marine ecosystems and driven million-year-old species to the brink of extinction. According to a study published in Science, less than 4 percent of the oceans remain unaffected by human activity. Over a billion people rely on fish and seafood as their main source of protein and hundreds of millions of people depend primarily on fishing for their livelihood. The oceans provide us with more than $20 trillion annually in ecological goods and services, but the ocean’s health is declining at an alarming rate due to destructive fishing practices, pollution, climate change, and a multitude of other factors. If we do nothing to help restore the delicate balance needed for a healthy ecosystem, the world’s fisheries will continue to collapse, coastal economies will grind to a halt, and millions of people will go hungry.
