Starting point oRGANISE a class debate. Why are oceans essential to life? Are there enough fish to feed the world's population? What happens when a marine species disappears? Oceans are essential because they produce oxygen. When a species disappears, it affects other species that depend on it. Fish are a source of healthy proteins. Fishing provides food and jobs for millions of people around the world. However, fishing also threatens sea life. If we continue to catch so many fish, many species will disappear.
