Believe itor not, oceans and seas are easy to be harmed by the development of humansociety. They are also influenced by man-made pollution easily. It is human beingsthat do great harm to the ocean ecosystems (生态系统).
The coralreefs (珊瑚礁) are fine ecosystems thatprovide food and protection for many ocean creatures (生物). The coral in almost all of the oceans is in danger frompollution. Chemicals from factories end up in the seas and oceans and destroy (破坏) coral reefs. If the coral systems die, some ocean creatures willbe sure to die out.
Protectingthe ocean also has something to do with the protection of ocean wildlife likedolphins. The fishing industry depends on modern ways to catch many fish inorder to earn more money. But the nets for fishing also catch other seaanimals. The fishing boat workers are advised to check their nets and set otherocean animals free. But the boats are in a hurry to make money and often otherocean animals are caught with fish.
Oil spills(泄露) can destroy the oceanenvironment because oil kills all ocean life. The world depends on oil andbecause there is plenty of oil off the shore (岸) inmany countries, the need for oil is more important than the risk of the oilspill. However, the fact is that one ocean mistake can lead to an oceanenvironment accident that will cause years ofdamageto the fine oceanecosystems. Oil spills will kill all the creatures in the area of the spill.The oil will be washed up on the shore and destroy the ecosystems along theshore, including birds.
Everyonewho cares about the environment should pay more attention to protecting theocean, and all of us should do something for the protection of the ocean.
