The Problem of Pollution

Recent years have witnessed increasing attention to the problem of pollution across the world. With social and economic progress, increasing numbers of technology-based products have flooded the world. Along with convenience, they have generated a lot of waste harmful to the environment and life. Today, clear skies and clean rivers are more like a legend passed down from old generations. This suggests the impending seriousness of environmental problems.

In terms of particle pollution PM2.5, studies have shown that half of the year is filled with poisonous gases. People who work in such environments are likely to suffer from various diseases or cancer. PM2.5 gets into the body by the nose and enters the lung, gradually accumulating to a point that could cause a fatal disease. This indicates a need for a better understanding of environmental pollution and strategies for more effective environmental conservation.

People are to blame for air pollution. People cut down many trees to heat homes or make paper. Trees absorb carbon dioxide and other greenhouse gases and release oxygen. They also protect land from soil erosion. Without trees, the environment has little protection. Greenhouse gases can disrupt weather patterns and reduce air quality.

The most important contributor to air pollution is the use of automobiles. With rapid economic development, many people now own cars for daily use. However, few understand the serious implications of using cars in terms of air quality. Cars account for a large portion of fossil fuel use, which is a key factor behind global warming and air pollution. That is, cars produce poisonous gases and carbon dioxide, and the worst part is the chemical reaction in the engine that makes gases even more lethal. Pedestrians are exposed to these gases and thus are at a greater risk of developing a fatal disease. In addition to personal cars, countless trucks and other commercial vehicles further exacerbate air pollution. For example, emissions from low-quality trucks are 500 times those from cars.

Studies have shown that strict compliance with rules and regulations would cut emissions by up to 60%. However, it is difficult to enforce such compliance, particularly because most people depend on the industrial sector for their livelihood. In this regard, the problem, unless appropriately mitigated, is expected to worsen over time.

In sum, it is now time for people to do something about protecting the fragile environment by controlling air pollutants such as PM2.5.This is the only way to leave behind a better world for future generations.
