Acid rain is rain or any other form of precipitation that is unusually acidic. It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the production of sulfuric oxides into the Earth's atmosphere with positive results Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased.[2][3] In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England.[4] Though acidic rain was discovered in 1852, it was not until the late 1960s that scientists began widely observing and studying the phenomenon.

4/14/2019 Nimetu dokument - Google'i dokumendid Essay In todays society there`s a huge problem with waste and global warming.

It means surroundings in which people, animals and plants exist. These are the things that we need, to be alive, but they are also many man-made things and technical progresses that harm the nature. Therefore we can´t live on this planet without basic components which are needed for human existence - air, water and soil. Firstly air, which is mostly a mixture of oxygen and nitrogen.
