It is a common belief that the major environmental problem is the loss of particular flora and fauna. However, I firmly believe that there are more important environmental issues, such as a air pollution by emitting gas from vehicles.
On the one hand, some people argue that the loss of specific plants and animals is the main environmental problem. This is because people think the nature is the solution of air pollution or global warming by producing the fresh air. For example, there are many floras and faunas in Amazon. Therefore, it makes lots of oxygen and helps to alleviate the air pollution happening all over the world.
Nevertheless, I support the idea that there are more important environmental problem, since people make lots of toxic substances in their life such as exhaust gasses and industrial wastes. Furthermore, today vehicles have become an essential part of our life. This is because the cars are highly involved in our livelihood. Thus, even though these motor vehicles emitting great amount of CO2, it is difficult to stop using them immediately. According to many statistics, there are lots of smog in the cities where many people live. The temperature of the globe also rises year by year.
To sum up, while it is apparent that the flora and fauna is the main factor for the environmental problems. However, it is undeniable that using cars, factories and so on are more harmful for nature. Therefore, people should find a better way to resolve this problems.
