The Future of the all Species

Summay Response- Practice

In Bhattacharya’s (2004) article, “Global warming threatens millions of species”, she claims that 25 per cent of the species, especially for land animals and planets, would be extinct by 2050, because of global warming. She quoted the study from Chris Thomas at the University of Leeds, UK, and colleagues that classified the climate change as mild, moderate and severe for all the species. She pointed out that the minimum climate change might drive all of the species to move into a warm area and try to adapt in the climate. It will lead the original habitats of some species to be invaded by alien species and exploited by human’s activities in order to get more land for living. According the article, Stuart Pimm, said that once the habitat has been destroyed, between 10 and 30 per cent of species would face being endangered. Moreover, some species that rely on plants to survive would be dying out.

Today, there are 1103 species that are still alive and most of them are only suitable in special areas, such as the Amazon, which has the biggest rainfall in the world. Although some species can adapt to the climate change, some species can only live in particular environments. It is hard to find the same conditions that provide the same factors to make them grow.

First, it is impossible for all of the species to move into a new place. For example, polar bears only can hunt in the freeze season. Once the Arctic loses its ice cover, they will be extinct. There are rare species that can migrate to a new environment that must be smaller than the old one. All of the clues show that the only way for these species is extinction.

Next, the climate change is related to human’s activities. In order to have the better life quality, people have used natural resources without limits, or have overproduced the greenhouse gases to the atmosphere, which heats up the whole planet. For example, illegal logging is the primary reason that causes the Amazon to lose its rainfall by about 40% in the recently years.

In conclusion, climate change leads to an unavoidable consequence such as decreasing habitats and species extinctions. In order to cut off the bad result for all the species, we should take some actions to stop the global warming that include cutting the emissions of greenhouse gas, which is the primary factor to heat up earth, finding new energy resources, such as solar energy or other nature capitals, and decreasing the discharge of carbon dioxide.
