We all need oxygen. Every living thing needs oxygen, except plants, because they need carbon dioxide and release oxygen as a waste product. For people, breathing dirty air will have negative side effects. The question is, what are we doing to make the air cleaner? According to EPA.gov, the Clean Air Act, which was passed in 1970, has "lowered levels of six common pollutants -- particles, ozone, lead, carbon monoxide, nitrogen dioxide and sulfur dioxide -- as well as numerous toxic pollutants." Progress has definitely been seen: the hybrid car, which uses less gas and reduces the user's carbon footprint. However, we can still see that many areas around the world do not meet their air standards. Many provinces in China have very bad air, for example, but that could probably be due to a high population. Places like in Indonesia do not have a good air quality, and that also has to be fixed too. The country is not highly populated like China, so what is it now? Air quality is a very important thing, as bad air can have terrible health effects. Things are being done right now to improve the air standards. It is true that we can never have pure air like in labs, but we need to have air in a state that is half by for everyone to breathe, no matter where people are. This is why I think that air standards everywhere need to be imposed or improved.
