Haha, apparently there is a positive side to acid rain... Apparently it's helps
Acid rain is the result of industrial pollution, which causes rainwater
to carry small quantities of acidic compounds such as sulphuric and nitric acid.
Contaminated rainwater can upset rivers and lakes, killing fish and other organisms
and also damage plants, trees and buildings.
But the new study shows that sulphur in acid rain, may have benefits, limiting
global warming by counteracting the natural production of methane gases by microbes
in wetland areas.
