Ozone pollution is the biggest problem. Ozone pollution is really an increase in the concentration of ozone in their air at uv ground level. Because the sunlight has a critical role in its formation, ozone pollution is principally a daytime problem in the summer months. Ground-level ozone is produced when sunlight combines with hydrocarbons and nitrogen oxide, two compunds produced by cars, trucks, factories, and power generating plants and found wherever gasoline,diesel or natural gas are combusted. So these gases are going to affect our life.
Another effect is that the nature is dying. Some air pollutants harm plants and animals directly. Other pollutants harm the habitat, food or water that plants and animals need to survive. When air pollution causes acid rains, plants that rely on rain water to live and grow are endangered. However all these pollutants are causing changes to the places where plants and animals live around the world.
The next effect are illnesses. People have no choice but to breathe the air around them. When it is polluted, they breathe in ozone, particles, and harmful gases that can hurt their lungs, heart and overall health. Air pollution can cause burning eyesand breathing problems, such as asthma or severe bronchitis. Also ultraviolet radiation causes skin cancer.
In conclusion, pollution is really a big problem in the world beacuse it is causing ozone depletion, nature dying and many different illnesses. People are creating new projects that will be good for the humanity. But If we dont take conscience about these problems, maybe in the future we will have more problems. So we need to try to avoid pollution.
