Answer 2

Air pollution as we know it today was a product of the industrial revolution, which was when the industrial processing of fossil fuels began. Another great kick was World War II, which drew attention to the dangers of radioactive waste and with it the whole issue of pollution. In 1952, an especially bad bout of air pollution in London killed over 4000 people. The catastrophe, later christened the “Big Smoke”, led to the Clean Air Act of 1956, which is considered  the first example of modern environmental legislation.



What do we have today?

Despite the countless efforts of organizations, laws and individuals, we still live in a world where air pollution is a global problem with multi-faceted consequences. It contributes to the greenhouse effect and global warming, as well as to numerous medical conditions such as lung diseases and cancer. Arguably the most notable pollutant today is carbon dioxide, which contributes to both the environmental and medical problems of pollution.
