Do Plants Feel Pain?

I have heard many non-vegans argue that plants feel pain, and that if vegans were so concerned about the suffering of other living beings, vegans wouldn’t murder plants either.  They often go on to say that since humans have no other way than to cause another life pain, then we might as well keep killing animals and plants so we can survive.

“Everyone knows the difference between taking a carrot out of the ground and slicing a pig into pieces.  Everyone knows the difference between mowing a lawn and tossing a live baby male chick (egg industry) into a rendering machine.  If one does not understand the difference, then that person is disingenuous, irrational and illogical.  The fact that some people compare carrots to cows proves how muck-deep in oppressive thought meat-eaters truly are.”  ~Gary Yourofsky, ADAPTT.org
