Every year air pollution is responsible for the premature deaths of over 3.7 million people worldwide, particularily because of its destructive effects on the cardiovascular system, and it is hence thought to be the primary cause for heart attacks. Most populations exposed to concentrated air pollution are often associated with increased heart attacks, lung cancer, DNA mutations, and premature births and deaths.
A recent test conducted on 38 U.S. streams has revealed the presence of over 350 chemicals in water supplies all across the nation. Even the most remote streams that remained untouched by developments contained at least one of the chemicals tested for, and some even carried up to 162. The effects of these chemicals is yet to be determined; however, many could be potentially detrimental to aquatic lifeforms, human health, and the overall food chain as a whole.
