As we all know, there are varieties of resources in the depths of the sea. However,     1     (随着时间的流逝)，some marine creatures have died out. Therefore, marine pollution has been of great global concern.

First of all,     2     (迫切需要) make people aware of the importance of protecting the ocean, because     3     (保护海洋就是保护人类，不定式作主语和表语).     4     (与此同时), we     5     (赞成政府采取有效措施) to keep the balance of nature. No matter how great the difficulty is, we will have the marine resources properly     6     (exploit) and never will we give up protecting the ocean.

One day, while Tom was behind the wheel, some yellow vests     1     (分散了他的注意力). It is some volunteers dedicated to environmental protection work who are cleaning up the garbage on the roadside.     2     (相比) those who spit in public and litter about, these volunteers       3     (激励他做一些促进环境保护的事情). On reflection he decided to join the volunteers since the beautiful environment       4     (依靠每个人的贡献).

Fishing is one of the most     1     (strike) drivers of declines (降低) in ocean wildlife populations. Catching fish is not naturally bad for the ocean and without doubt     2     (accept), except when boats catch fish faster than stocks (储备) can catch up, something called overfishing.

The damage done by overfishing goes     3     (超出……范围) the needless loss of billions of fish. The number of overfished stocks     4     (global) has increased a lot in half a century and today one-third of the world’s fisheries are being pushed over their biological limits, according to the Food and Agriculture Organization of the United Nations. It is shown by a new study that more than one-third of all sharks and rays are now at risk of     5     (extinct) because of overfishing.

Overfishing is closely tied to bycatch — the catch of unwanted sea life while fishing for a specific species. This, too, is a serious marine (海洋的) threat that     6     (导致) the needless loss of billions of fish.

Billions of people rely on fish for protein, and fishing is the main livelihood for millions of people     7     (全世界).     8     (因此), governments and regional fisheries bodies must     9     (采取行动) now to stop overfishing and prevent a global crisis. To our relief, many people who make a living by catching and selling fish are working to promote how the world manages and protects ocean resources. WWF works with a lot of organisations to reform fishery management     10     (在全世界), focusing on sustainable (可持续的) practices that not only protect ecosystems, but also sustain livelihoods and ensure food security.
