What are the environmental hazards caused by automobiles?

The environmental hazards include the greenhouse effect, traffic congestion, etc. The following are specific introductions to the environmental hazards caused by automobiles: 1. Exhaust emissions: While burning gasoline to obtain power, automobiles emit carbon monoxide, which damages the ozone layer that protects the Earth. Without the protection of the ozone layer, the Earth's temperature rises, sea levels increase, and land area decreases. Scientists refer to this as the greenhouse effect. Although the greenhouse effect may not destroy humanity, it makes human survival extremely difficult, and automobiles are the main contributors to the greenhouse effect. 2. Traffic congestion: The original intention of inventing automobiles was to make transportation more convenient. However, due to the rapid growth of automobiles and the inability of road construction to keep up, severe congestion has occurred in major cities across the country. During peak commuting hours, it is common to see the tragic scenario where cars that could originally travel at speeds of one to two hundred kilometers per hour take two hours to cover two kilometers. This greatly reduces social production efficiency and causes resource waste.
I think the environmental burden of cars is quite significant. Starting with daily driving, exhaust emissions contain large amounts of carbon dioxide and harmful substances, exacerbating climate change. Global warming is a major issue, and I often see hazy skies in the city, caused by smog and acid rain from these vehicles. Health-wise, the situation isn't optimistic either, as air pollution leads to an increase in respiratory diseases, making children more susceptible to asthma. In terms of resource consumption, the more gasoline we burn, the more natural ecosystems are destroyed by oil extraction, and car manufacturing itself is highly energy-intensive. In the long run, some of the plastic pollution in the oceans even comes from discarded car parts. That's why there's a push now for electric vehicles or greater use of public transportation—every little bit helps. We must act together to protect our planet.
