Yes, rainwater is naturally acidic due to the presence of carbon dioxide in the atmosphere .
However, the combustion of fossil fuels emits nitric oxide and sulfur dioxide, also acidic substances, into the atmosphere.
Harmful particles emitted from power plants, cars or mining sites are easily carried hundreds of miles away from their original source and then pollute pristine natural areas.
Throughout the years, scientists have observed numerous examples of this worrisome phenomenon.
The effects of Air pollution are very harmful for health.
It causes different kinds of respiratory diseases like heart attack, Cancer, bronchitis etc.
For example, more than 50 percent of trees in the Black Forest, Germany, died and over 60 percent of the beech and yew trees in Great Britain showed signs of acid rain exposure Eutrophication occurs where an overabundance of plant nutrients (nitrogen, phosphorus) accumulates in freshwater bodies and causes an overgrowth of algae in water.
The excessive algae growth is dangerous for other aquatic organisms, because once the algae die, their decomposition depletes oxygen from water.
As ozone layer will go thin, it will emit harmful rays back on earth and can cause skin and eye related problems. Toxic chemicals present in the air can force wildlife species to move to new place and change their habitat.
The toxic pollutants deposit over the surface of the water and can also affect sea animals. Ozone exists in earth’s stratosphere and is responsible for protecting humans from harmful ultraviolet (UV) rays.
