Every time an old computer breaks down, it needs to be dealt with safely. What is worse, at present, broken computer parts are usually buried. It may be hundreds of years before they are really gone in the earth.Many places in China are polluted by ewaste. Guiyu in Guangdong Province is one of them. This town is named as “the ewaste capital of the world〞. It has to deal with 1.5 million kilograms of ewaste each year, from which it makes 75 million yuan. But it comes at a cost. Many of the poisons in ewaste find their way into the environment. An environmental group has found the air, the earth and the rivers in Guiyu are badly polluted.Luckily, the Chinese government wants the country to change the situation. China has passed a new environmental protection law, the strictest one we have ever had. Computer companies like Lenovo and Dell are asked to take back their old computers.

This famous and expensive dish is especially popular in southern China. But do you realize that you’re killing a whole shark each time you enjoy a bowl of shark fin soup?When people catch sharks, they cut off their fins and throw the shark back into the ocean. This is not only cruel, but also harmful to the environment. Without a fin, a shark can no longer swim and slowly dies. Sharks are at the top of the food chain in the ocean’s ecosystem. If their numbers drop too low, it will bring danger to all ocean life. Many believe that sharks can never be endangered because they are the strongest in their food chain. But in fact, around 70 million sharks are caught and traded in this industry every year. The numbers of some kinds of sharks have fallen by over 90 percent in the last 20 to 30 years.Environmental protection groups around the world, such as Wild Aid and the WWF, are teaching the public about “finning”. They have even asked governments to develop laws to stop the sale of shark fins. So far, no scientific studies have shown that shark fins are good for health, so why eat them?
