Is this true？ Will we run out of fish one day？ Humans began overfishing(捕捞过度) in the sea in the 19th century. Today， there are too many fishing ships in the world. In other words， we are taking away too many fish from the sea. The fish can’t grow back fast. So， the number of many kinds of fish is dropping rapidly. Some kinds will soon be in great danger. 返回目录 上一页 下一页 To stop overfishing， many areas have started to do something. The governments have put up “No fishing” signs near some rivers and lakes. The fish in these areas are probably under protection. When the fish in a certain area start to lay eggs(产卵)， the governments will announce(宣布) the beginning of the closed fishing season. People can’t catch fish until the young fish grow up. All living things here depend on the sea. And fish are very important to the health of the sea. Let’s work together to protect our friends in the sea. 返回目录 上一页 下一页 4. When did human begin overfishing？ (不超过5个词) ⁠ 5.
