Some More Stuff to Know
Effects of Acid Rain
What it Does...
Damage of trees
Pine needles are withered away, leaving nothing but barren branches.
Eroding stonework
Historical monuments are being worn away.
Disrupted chemical balance of soil and water
This includes lakes, rivers, streams, ponds, anything.
Interference in animal reproduction
Animals that depend on unsafe waters have trouble reproducing healthy offspring, if at all.
Human health issues
Levels of Acidity
Not Just Rain
Pure water: 7 on the pH scale (neutral)
Normal rainfall: 5.6
Acid rain: 4
Acid rain in Indiana: 4.3-4.5
Levels of acidity are found by collecting samples of rain and measuring its pH.
Acid rain comes in basically any form of weather, which means snow, fog, dust, smoke, mist, etc. are all potentially harmful.

Discovery
Robert Angus Smith first coined the term "acid rain" in 1852, when he noted the connection between England's air pollution and the acidity of its rainfall.
In other words...
Our air has higher levels of acidity than it should, and this in turn spreads to the rain, spreads to the land, and messes with our environment.
Societal Issues
Caused by...
Even if cities are the primary source of smokestacks, power plants and heavy traffic, the damage from those culprits are carried off by winds and affecting countrysides and even Canada.
In retrospect, no area is safe from acid rain. Just to make it worse, Indiana holds one of the highest levels of acidity in the nation.
Compared to the rest of the country...
What is Acid Rain?
Vegetable decay and volcanoes -- if all causes were natural, then the level of acidity would remain normal.
However, humans burning fossil fuels for daily needs and driving cars that emit heavy exhaust push that pH number lower than what's safe.

"Acid rain is the deposit of wet and dry material from the atmosphere that contains abnormally high levels of sulfuric and nitric acids."
