                   The impact of society on the environment. 




Acid rain
  The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rainwater can leach aluminum from soil clay particles and then flow into streams and lakes. The more acid that is introduced into the ecosystem, the more aluminum is released.




Global warming
The planet is warming, from the North Pole to the South Pole. Since 1906, the global average surface temperature has increased between 1.1 and 1.6 degrees Fahrenheit even more in sensitive polar regions. The heat is melting glaciers and sea ice, higher sea level, shifting precipitation patterns, more storms, more floodings, rising of new viruses, and setting animals on the move.




The Rise of Powassan Virus
This virus has been known from 1958 in the USA.The disease had been rare in humans, but ecological changes have resulted in the pathogen spreading to the common deer tick, the same insect responsible for Lyme disease. This change could result in many more human infections.Severity ranges from none to fatal(only 10% of brain infection).No specific treatment, just supportive treatment we could do.
