Most of the different species of animals and fish depend on simple plants for their food. The simple plants called algae (海藻) drift near the surface of the ocean and u sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important awater is!     Each plant or animal in our as and oceans is an important link in a food chain. The algae are eaten inlarge amounts by microscopic animals, which are in turn consumed by larger animals. The food chainsare delicately balanced. The bad news about the food chains in the oceans is that they are under threat becau of man. People once thought that the oceans were so big that it didn't matter if we dumped rubbish into them or caughthuge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceanshave started to drop.     Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats (海域). Most countries have introduced fishing restrictions (限制)to protect fish stocks in the oceans and new techniques are being pioneered to deal with pollution. Finally,the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future.
