Many acid rain producers are industries and power producers in the midwest and ontario regions of north america, yet damage from acid rain occurs as far east as the northeastern united states and eastern canada. what conclusion can we draw from this pattern?

The regions that does not have any industries suffer the consequences of the acid rain rather then the producers in the Midwest and Ontario regions of North America.    

Acidic rain is formed by SO2 and NOx produced in industries. The gases mix in rainwater to produce acids and it affects the environment mainly the forests and lakes. Despite the industries based in the United States, the weather shifts pollution towards Canada and northeast of America. It is noted that more than 50%  of Canada's acid rain appears from the United States.
