As the number of private cars has increased, so too has the level of pollution in many cities. due to the release of dioxins into the environment and it begins to die, this affects the atmosphere, smog begins. Also, in addition to environmental pollution, they also cause harm to human health and harm to animals, people begin to get sick often and their immunity weakens, and animals begin to die. I think to solve this probem, people need to switch to green energy, since green energy does not harm the environment and is also cheaper than regular gasoline or gas. There are also cars that run on solar batteries, and there are electric cars like Tesla, such vehicles are more environmentally friendly and do not harm the environment. The only catch is that not all countries have electric cars and there are no electric gas stations. I believe that in order to protect our nature, humanity needs to switch to green energy and make electric cars more affordable so that everyone can afford them.
