The effect of global warming oo coral reefs - summary response #1 -

The Effect of Global Warming on Coral Reefs



In the article, “Global warming may have damaged coral reefs forever,” the author explains what the problem of global warming is to coral reefs and the effect of sea temperature changing on coral and fish communities. According to the author, global warming is destructive to coral reefs. Some terrible examples of global warming include the death of 90 percent of coral reefs near the Seychelles Islands, due to temperature increase. The long-term effect of high temperatures in the oceans is that they cause corals to be unable to reseed and recover. If global warming ruins the reefs, fishes will lose their food and shelter from the reefs, and fishes will suffer local extinction. Moreover, if herbivorous fishes are extinct, the ocean cannot control algae spread problems. After the awful incident, often reefs are recovered, but if structures of reefs fall down badly enough, recovery time will be delayed. Unluckily, many coral reefs are gone; we are too late to save them, but people should try to decrease greenhouse gas and global warming to save other wildlife.

This article explains about the effect of global warming on coral reefs. Coral reefs are very sensitive, so if water temperatures are changing even little bit higher, most of them may die. If coral reefs disappear, the marine fish that lives in the coral reefs and find food in the coral reefs will lose their area. It is too late to restore coral reefs areas that are gone, but to save other animals, people should take care of the greenhouse gas problem, climate change and global warming. Therefore, people have to change their bad lifestyle. Global warming is destructive to coral reefs; some kinds of herbivorous fish are extinct and aquarists take fish and corals from ocean for their fish tank; those things are making oceans devastated.

First of all, coral reefs are gone because of global warming. Some reasons may hurt coral reefs but the biggest reason for ruined coral reefs is global warming. The author says, “global warming has had a more devastating effect on some of the world’s finest coral reefs than previously assumed” (2006, para. 1). That is a long-term effect; the ocean’s temperatures are slowly going up, and that is killing off many corals in the ocean. It is caused by global warming, so if people are aware of that problem, they should take care of our environment for the nature.

Second, herbivorous fish become extinct from the dead coral reefs and the effect of this spreads. Many herbivorous fish need a hiding place and take food from coral reefs, but if the reefs are gone, they cannot live anymore. So it will affect the carnivorous fish; it may make them die because carnivorous fish need herbivorous fish to live to eat for food. According to the author, “the collapse of the reefs removed food and shelter from predators for a large and diverse amount of marine life” (2006, para. 6). So global warming will cause ecological disorder; first it makes coral reefs go away, and takes herbivorous fish’s area, after this effect, the carnivorous fish die.

Finally, some saltwater aquarists also waste coral reefs and fish species from the ocean for their own fish tank. After the showing of the movie “Nemo”, many people have an interest to marine fish tanks and made it their hobby. Marine fish and corals are gorgeous to look at, so after that movie the demand for ocean species was increased by people. That also ruined coral reefs and marine fish; many people’s self-centered mind made them sick. I heard about marine fish from Korean experts. In my case, I had a fish tank in Korea. So I usually visited fish experts' house to have a piece of advice and talk about fish. One piece of his advice was very interesting to me. He said, “Marine fishes and coral’s are hard to breed” so the marine fish costs are expensive and unique. But freshwater fishes are not much like that. That is why fish demands are increasing, so marine fishes are in danger. For saving those species, the government which has popular fish in their country, should make a limit to protect their fishes or try to make a fish farm and breed fish system activity.

In conclusion, global warming wastes our living things in the ocean; for example, coral reefs are gone; fish species have changed and been devastated. The cause of global warming is people’s using fossil fuels, cutting trees and similar activities. Those things cause the greenhouse effect, so the earth becomes warmer. That is not just one country’s problem, it is every country’s problem; if people want to solve their problems with our natural species, they should get together and take care of them.
