Oceans cover 71 percent of the globe, and they are as important to us as they are vast. Our oceans are home to most of the life on our planet and play a central role in the world's natural systems, like regulating our climate and absorbing carbon dioxide. They provide livelihoods to countless fishermen and others around the world. They also feed hundreds of millions of people and have the capacity to provide a healthy seafood meal to a billion people, every day. Unfortunately, the oceans are in trouble — scientists report that the amount of fish caught from the oceans began declining — for the first time in recorded history — just a few decades ago.
