The Exterminations of Animals and Plants

Bhattacharya (2004) states in her article that global warming is being accelerated in the world. Chris Thomas at the University of Leeds and Stuart Pimm at Duke University warned that global warming can affect extinction of animal species and plants. Thomas and Pimm consider the problem of global warming is very serious. Climate change will result in loss of ten to thirty per cent of species due to destruction of their habitats. Thomas’ study says every species needs environment that is fit for its issues such as temperature and rainfall. As the earth is warming up, species are migrating to new place that are suitable for them. However, some species are not able to migrate because of their physical issues, thus we will lose a lot of species. Both Thomas and Pimm say we need powerful action to prevent global warming.

Global warming has come up as one of the biggest concerns of human society. As global warming is getting worse, animals and plants species are doomed. The earth is warming up day by day, so the habitats of species are disappearing. Global warming is definitely baleful for both human society and our nature. We should obstruct global warming by regulating some substances.

First of all, using fossil fuel can be replaced. Fossil fuel accelerates global warming. Fossil fuel is one of necessary elements of human life- for transportation, heating, and generating of electricity. It’s a properly important element of human life, but it can be replaced by other types of energy. For example, solar energy is the one of alternatives. It heats your place without any fossil fuels. You can also use wind-force. Wind-force is one of method to generate electricity. It is beneficial in a few ways. Wind-force is nature-friendly because it doesn’t hurt nature, and can generate electricity. Changeover of energy resources can help to obstruct global warming.

Moreover, every country must have a severe law to regulate using CFC. CFC is one of the fountainheads of global warming. Refrigerators used to have CFC for cooling. Many countries regulated using CFC in refrigerators, but a few countries are still using it. CFC is the deadliest mischief in hurting the ozone layer. The function of the ozone layer is sunlight filter. As ozone layer is becoming thinner, many problems- including global warming and skin cancer-have come up. Therefore, CFC has to be replaced with other materials.

In conclusion, global warming is a really serious problem that we have, but it can be prevented essentially. Global warming has been caused by humans, so it can be stopped by humans, too. We have to change our lifestyle- using fossil fuel less, and using invention and incitement of alternative energy. On the other hand, lack of concern for nature and animals made us use fossil fuel and CFC, and they have been accelerating global warming. At this time, everyone knows what is helpful for us, and what is harmful. We must bring out our prior surroundings. We can do it.
