Because it causes acidification of lakes, soil and ecosystems and can impact human health.

Explanation:

Acid rain used to be a local, regional issue that was largely confined to say Europe or North America. Acid rain in these two regions is actually getting better with governments passing regulations against emitting SO2 and Nox gases from industrial facilities.

However, a lot of the world's manufacturing and industrial facilities have shifted to China and S.E. Asia and so this is where the acid rain problem is now. But it isn't staying in China and is increasingly drifting across the Pacific Ocean, back to North America - its now called "The Asian Brown Haze"
