By Jove my old chap, how would you like to hear about acid rain what-what?

This particular picture here elucidates the way Acid Rain can hurt the little birdies, which make the lassies sad.

Acid rain soaks up all of the hullaballoo and hogwash on the ground, namely CaCO3, a compound needed by the snails that call their home there.

The bird's main source of calcium were the snails, so now that the snails can't get enough calcium the birds can't either.

Dear me old chap, that is quite the sticky wickett!
