The world is becoming hotter and more crowded, as our engines continue to pump out filthy emissions, while half the world has no access to clean fuels or technologies. The air we breathe is rather polluted. Research demonstrates that nine out of ten people breathe polluted air, which kills millions of people every year.
The ramifications of air pollution are serious. Studies indicate that one-third of deaths from stroke, lung cancer, and heart disease is because of air pollution. Microscopic toxins in the air can glide past our body's natural defenses.
These pollutants infiltrate deep into our respiratory and circulatory systems, and they cause damage to our heart, lungs, and brain. The lack of visible smog is no indication that the air we breathe is healthy.
