U.S. Cities Report Cleaner Air, as Said by EPA

The Environment Protection Agency on Thursday claimed that the air in the American cities is becoming safer to breathe. Due to continued efforts and awareness, momentous growth has been recorded which reveals reduction in the levels of harmful substances in urban air, especially in recent decades.
The most phenomenal aspect is that from the year 1990, there has been a 60% reduction in the levels of mercury from coal fired plants and a 66% decline in Benzene as well as a significant drop in lead which is responsible for brain damage in children.
EPA also claims that a reduction of 3 Million tons of toxins per year from vehicles have been notices that have contributed to the health of the environment. The hazardous air contaminants have also reduced phenomenally from the air which accounts for clean breathing atmosphere. These pollutants that have now been reduced from the atmosphere have been responsible for many diseases like respiratory disorders, cancer, neurological disorder and problems with reproductive systems.
The urban air population has been deemed much cleaner for consumption versus what it used to be. There has been a tremendous success when it comes to effective measures to curb air pollution. All the Americans can take the proud credit of this amazing initiative which has been going on for 40 years and has made people more aware and more responsible towards their environment.
