People hold different opinions about what exactly today’s biggest environmental problem is – whether it is the fact that some animals and plants species are disappearing or that there more serious problems. Notwithstanding the severity of the former problem, I believe that there more significant issues regarding environment such as global warming, fresh water deficiency and forest fires.
To begin with, the loss of some species of plants and animals is undeniably a serious issue to ponder on, for it does effect food chain in the world. Nature has always kept the balance well between prey and predators, thus preventing one species from completely disappearing. However, the strongest predator in the history of earth, humans, may have distorted that balance, which is in turn threatening some species with complete eradication. Undoubtedly, the loss of one particular type of animal or plant could be detrimental since even the smallest, seemingly useless species, may have a crucial role in food chain. For example, the decision made by chairman Mao of communist China to completely wipe out all the swallows in the country resulted in the increase in a grasshopper population. As a result, huge number of grasshoppers, main diet of the swallows eradicated, ate all the crop produced by people causing the greatest famine in human history, claiming roughly 30 million lives. Given the historical evidence, the loss of a particular animal or plant is indeed a very serious environmental problem.
However, there are more serious environmental problems that people should be worried about these days. Firstly, global warming that is getting more acute year by year affecting the lives of millions. It most importantly melting ice glaciers in south and north poles, which therefore is causing an increase in sea level, jeopardizing coastal cities. Also, there is more precipitation now than in the past due to the change, and it is putting the lives of many who live in mountainous areas in danger as more snow and rain increases the chances of landslides and floods. Secondly, shortage of drinkable water in many parts of the world is yet another more important problem regarding environment. It is estimated that more than a third of world’s population suffers from fresh water deficiency. Finally, forest fires, which have risen in frequency over the last 2 decades, are another serious environmental problem we have to deal with. Not only are they destroying many habitats but also adding to the carbon dioxide emission. It comes as no surprise that trees filter the air by taking in CO2 gases, which are poisonous to people, and releasing oxygen. These are, in my opinion, more serious problems people need to worry about, for they are literally killing us.
To conclude, by no means is the loss of a particular species not a serious issue because it can destroy food chain which may kill millions like in the case of famine in China. Nevertheless, global warming, water deficiency and forest fires seem more serious because they are already affecting people by destroying the homes and depriving them of oxygen.
