問題詳情


(C) At the beginning of the 21st century, the world is changing in important ways. Until recently, nations acted independently. Each country did its business and tried to solve its problems alone. But now, the economy is worldwide and communications technologies have connected people all over the globe. Many problems are global, too and can no longer be solved by individual nations.Environmental destructions is one of these problems. As the world’s population has grown and technology has developed, the environment has suffered. Some nations have begun to try to stop pollution and environmental destruction. But the environment is global—the atmosphere, the ocean, and many forms of life are all connected. Thus, the solutions require global thinking.The problem of ocean pollution is a good example. All the oceans of the world are linked. Pollution does not stay where it begins. It spreads out from every river and every harbor and affects bodies of water everywhere.For centuries, people have used the oceans as a dumping place. Many cities take tons of garbage out to sea and dump it there. The quantity of garbage that ends up in the water is incredible. Five million plastic containers are thrown into the world’s oceans every day! Aside from plastics, many other dangerous substances are dumped in oceans. These include human waste and chemicals used in agriculture. And every year, oil tankers accidentally spill millions of gallons of oil into the sea.Some people believe that the oceans are so large that chemicals and waste will disappear. However, many things, such as chemicals and plastics, stay in the water and create problems. They eventually float to shore and are eaten by tiny sea creatures. Then the large animals that eat tiny creatures are poisoned and die. Harbors and coasts around the world have become unsafe for humans and animals. The world’s fish population is rapidly shrinking.
