Air pollution is a horrible thing because people are polluting the environment, we can stop this by shutting down most of the coal fired power plants and lowering how much gases and other harmful things we put into the environment. Polluting the environment is hurting not only us but also the plants and animals. The reason why polluting the environment is bad is because it is putting holes in the ozone layer and is causes people to have major health problems like with their breathing. There are many different ways people can pollute the air. Smog is one of them also, greenhouse gases and carbon dioxide are all causes of air pollution.
        Smog is a major cause of air pollution. Smog is a mixture of fog and smoke or other airborne pollutants such as exhaust fumes. Smog comes from vehicles, machinery, factories, and paints. There are also many ways that we can prevent sit.We can cut back on how often we drive our cars or we can use alternative fuels. We can also stop using fossil fuels as much as we do and that will help out a lot .
        Greenhouse gases are warming up our environment which could lead to global warming. Greenhouse gas is gas that gets trapped. When it lets off heat into the environment that is what leads to the warming of the earth or what we call global warming. Global warming is when earth’s temperatures rise above average.This happens when the greenhouse gases trap heat and light from the sun in the earth’s atmosphere, which increases the temperature.We can stop this by reducing the energy we use at home by turning off lights when you are not in the room.
        Carbon dioxide is colorless and odorless and is not bad for the environment but too much is. It plays many important roles in the environment. Without it there would be no photosynthesis and without photosynthesis there would be no plants therefore no oxygen for us. Many people think that it is bad for the environment because it is a greenhouse gas required by the earth to maintain normal temperatures and sustain life. Carbon dioxide is not bad but too much of it can cause radiation from the sun to get stuck between the atmosphere causing global warming.
         In short, There are many things that people do to cause air pollution but there is also many ways that you can prevent it. Also, air pollution has negative effects on the environment.
