Factories have done unmeasurable damage to our ecosystem, that is unequivocable. But we had to rename it climate change because people couldn't get over the phrase global warming whenever it was cold so I don't see "Reduce Pollution!" as a winning slogan. People who care, care about the underlying concept no matter what it's called. People who don't care don't believe it's a problem in the first place and won't do anything to reduce pollution.
