問題詳情

四、閱讀測驗In recent years, various factors have threatened coral reefs and the life that depends on them as their home. Blast fishing is an illegal fishing method which involves setting off bombs in the water to kill as many fish as possible. Its negative effects on a reef are significant; it kills most living things and causes great damage to the reef’s structure.Fishing with liquid cyanide, a very dangerous and deadly material, is another threat to reef ecosystems, particularly in the Philippines. Fishermen release liquid cyanide into the reef and collect the stunned fish, which are then sold for big money to the aquarium market, or for consumption in restaurants. The fishermen often break apart the reef to look for hiding fish. The cyanide also kills large numbers of coral polyps, leaving large areas of the reef dead.Reefs are also damaged when coral is taken for building material, jewelry, or aquarium ornaments. Water pollution also results in damage. In addition, the recent warming of the oceans has caused areas of many reefs to turn white. Biologists are concerned that coral may be negatively impacted by further warming.Threats to coral reefs are serious, but there is reason to hope that they will manage to survive. If we take steps toward coral reef conservation, it is likely that these tiny creatures, which have survived natural threats for millions of years, will be able to rebuild the damaged reefs that so many ocean animals and plants depend on.
