There was a time in Los Angeles when air pollution reached absolutely critical mass. There were too many people driving too many cars. There were plants and factories. There was everything from the movie industry to the City of Industry. And it reached dangerous levels. Even fatal levels. At one time, it must have seemed like Los Angeles had gone too far and shot itself in the foot, creating a poisonous valley for all of its millions of residents. But the city and the state responded by cracking down on emissions from cars and factories. Cars needed to meet certain requirements, and they started treating gas to make it burn cleaner. Now you can easily see the San Gabriel mountains from downtown Los Angeles—a success story that proves that it is possible for even a city the size of Los Angeles to pull away from critical, dangerous levels of air pollution.
In order to reduce the amount of air pollution in urbanized areas, the government on a state and city level must work in accordance with the needs of the city and the people. That means creating a strong public transportation system, as well as offering incentives for local businesses to literally clean up their acts. They can also offer incentives for people who carpool, which Los Angeles has done with the creation of diamond lanes. Not only are they faster than the other lanes of traffic, but in some areas, they are not charged a toll. Air pollution must be reduced, though, because people will definitely suffer, even fatally so, if air pollution is not reduced in a responsible, thorough way.
National Park Preservation
National park preservation protects everything from deserts to forests, from vegetation to the buffalo.
Recycling is beneficial in some instances but shows a net loss in others.
