air pollution in the world

     India accounts for seven out of ten cities in the world with the worst air pollution.  According to Greenpeace and AirVisual, Gurugram is the world's worst polluted city. It's air quality index is three times the level which the US Environmental Protection Agency regards as healthy. Gurugram's air quality level averages at 135.8. Scientists say air pollution will cause around 7 million premature deaths globally and will have a major economic impact. "Air pollution steals our livelihoods and our futures," said Yeb Sano, executive director of Greenpeace Southeast Asia. Eighteen of the world's top 20 most polluted cities are in India, Pakistan or Bangladesh, including the major population centers of Lahore, Delhi and Dhaka. Climate change is making the effects of air pollution worse by changing atmospheric conditions and is increasing the chances of forest fires. The World Health Organization says poor air quality is the greatest environmental health risk. Air pollution kills nearly 10% of children under the age of five. It can increase the risk of strokes, heart disease and lung cancer.

Dual-fuel vehicles

A recent study shows that dual- fuel vehicles are benefiting the population but, turns out they are costing the environment. While substituting gasoline for ethanol gases, it causes an increase of ultra fine particle matter, with a 30% increase of atmospheric concentration. The problem is that they are less then 50 nanometers in diameter. The nano particles are also not track or regulated by the environmental agencies. We inhale these gases everyday, inhaling ethanol. The most practical way to reduce greenhouse gases is using electric, hybrid and biofuel care.   https://www.sciencedaily.com/releases/2017/08/170828124546.htm

Acid Zone in Chesapeake Bay Found

     According to the University of Delaware, the Chesapeake Bay is becoming acidic as it has gone to 7.4 pH from an average of 8.2. The oxidation of ammonia and hydrogen sulfide may be the factor that is leading to the higher acidity levels in coastal oceans, but it can eventually lead to more of open oceans. Naturally the waters of the Chesapeake Bay have a regulatory system that holds back the increase of acidity levels in the area, and this works as the dissolving of living shells, non-living aragonite, and calcite minerals. Though nature has a path to keep the waters in the Chesapeake Bay, humans should take more care of our Earth as we have a role in polluting the water and rising the acidity levels in coastal oceans. https://www.sciencedaily.com/releases/2017/08/170828093737.htm
