What are the environmental hazards caused by automobiles?

[AdalineLee]

Automobiles pose the following hazards to the environment: 1. Exhaust emissions issue: While burning gasoline for power, automobiles emit carbon monoxide, which damages the Earth's protective ozone layer. Without the protection of the ozone layer, the Earth's temperature rises, leading to higher sea levels and reduced land area. Scientists refer to this as the greenhouse effect. Although the greenhouse effect may not destroy humanity, it makes human living conditions extremely difficult, and automobiles are a major contributor to the greenhouse effect. 2. Traffic congestion issue: The original idea behind the invention of automobiles was to make transportation more convenient. However, due to the rapid growth in the number of automobiles and inadequate road construction, severe congestion now occurs in major cities nationwide. Often during peak commuting hours, cars that could normally travel at speeds of 100-200 kilometers per hour end up covering only two kilometers in two hours, a tragic scenario that frequently plays out. This significantly reduces social production efficiency and results in resource wastage.
