Acid rain is a rain which pours chemical water instead of a natural one. The main reasons are the emissions of sulfur and nitrogen from big factories. For many years, acid rains caused essential harms to the agriculture. This water can penetrate deep inside the soil and it will further be impossible to grow ecological production.
