How The Clean Air Act of 1970 reduced ozone pollution

As a result of the industrial revolution, the time had come to start getting serious about protecting the environment. There were many events that had influenced the Clean Air Act of 1970, such as the Donora Smog in 1948, and the Great London Smog of 1952. These events and many more, alerted people the potential effects that pollution can have on human health.

The Clean Air Act of 1970 is a federal law that allows the Environmental Protection Agency to set limits on certain air pollutants. It also gave the Environmental Protection Agency the power to limit emissions of pollutants coming from chemical plants, factories, and steel mills and to set national emission standards to be achieved. One of the most important ways this law created limits on air pollutants was that it set maximum levels for six pollutants – lead, solid particles, sulfur dioxide, carbon monoxide, nitrogen oxide, and ozone.

The reduction of ozone pollution has significantly increased since this law was passed. Since 1970, the six most common air pollutants have decreased more than 50%, air toxics from the large industrial sources have reduced to nearly 70%, and new cars are now more than 90% cleaner then ever. Clean fuel was one of the main problems addressed in the act since more than half of the nations air pollution comes from car, trucks, buses, boats, airplanes, etc. These vehicles are major contributions to the formation of ground level ozone, which is smog. Congress endorsed the President’s goal of setting tough standards for the revision of gas.

Due to the Clean Air Act of 1970, Americans breathe less pollution and face lower risks of premature death. It also reduces the environmental damage and thousands of peoples lives have been saved from skin cancer and cataracts due to the protection of the ozone layer. Since many of the regulations the EPA has issued have reduced the amount of emissions that go into the air, the quality of the air has improved and there is fewer air pollution among us. The Clean Air Act of 1970 was a major turning point when it came to reducing the air pollution and environmental situations in the country.

In 1990, the president, George Bush decided to take more comprehensive action for clean air. The Clean Air Act of 1970 had started to fall from its objectives and many areas failed to keep up with the required air quality standards. Bush, proposed a bill that would reduce smog causing pollutants by placing stricter auto emission standards. This would reduce 75% to 90% of the chemicals that are being released into the air. The bill that he signed permanently reduced sulfur dioxide emissions by 10 million tons permanently.
