Calamities of fossil fuels

Tak Keung Yiu writes:*

Fossil fuels are the most important resources in the world. However, they are also one of the major contributors to environmental pollution. Fossil fuels consist of non-renewable resources, which mean that they take a long time to be formed and are likely to be depleted before this occurs again. While predictions of the depletion of fossil fuel is subject to change as new sources are discovered, it is already widely accepted that, one day, they will be gone. The global consumption of fossil fuels has increased over the past century, meaning that prices have increased as well. As prices increase, more unconventional fossil fuels suddenly become viable alternatives.

The burning of fossil fuels emits nitrogen oxide emissions. This is a result of nitrogen and oxygen gases in the air combining at high temperatures due to combustion. It has become a major environmental problem. Nitrogen oxides are mainly a by-product of human activities, such as transportation and industry. These gases also cause acid rain which affects the health of forests and lower the pH levels of waterways. This contributes to decreased health in plants and animals that rely on these other natural resources.

It is a growing concern in many countries. China is one such country where increased industry has led to increased pollution. Tiny particles in the air lead to damage in human lung and cardiovascular tissues, contributing to cancer, cardiovascular disease, and asthma.

People must invest into renewable resources in order to lower the use of non-renewable resources. This will also help lower prices and reduce pollution from using Fossil fuels. Technologies should be improved to increase energy efficiency and pollution controls.

Bottom Line: Pollution from burning Fossil fuels can be alleviated by use renewable resources and improve the Technologies to increase energy efficiency.

In this article, the author clearly defines the axiom that overconsumption of fossil fuels will lead to a shortage of that natural resource. The abuse of fossil fuel has brought about diseases such as cancer and asthma, to people around the globe, and has polluted our environment badly. Moreover, the author suggests that, to slow the use of this non-renewable resource, substitution of it with a renewable resource is necessary. However, he fails to provide a real example about the replacement of fossil fuel. From my point of view, the author should suggest the use of solar power or wind power as the substitution for fossil fuel. New technological development concerning energy use cannot only delay the consumption of fossil fuel but also reduce the harm to both the environment and people’s health.

I agree with your opinion. Only the development of both new technologies and renewable resources can alleviate the environmental degradation and resource overuse problems. In order to solve these problems, we also need to come with up a workable, realistic management plan, and implement it in a timely manner
