The Importance of Protecting Our Oceans
As we all know, there are varieties of resources under the sea. However, the past ten years has witnessed that some creatures have died out. Therefore, marine pollution has been greatly concerned by the whole world.
On the one hand, we must make people realize the importance of protecting the ocean. As a matter of fact, to protect the ocean is to protect human beings. On the other hand, the government should take immediate measures to keep the balance of nature. In no way should we abandon protecting the environment. Only by raising people’s awareness of protecting the environment and making great efforts to prevent pollution can the problem be solved.
Thank you ！
