"Actually, I think pollution from any source anywhere is a part of a whole.  Our planet increasingly is polluted and, to some extent, we are all to blame.  There are little adjustments, though, to our lifestyle that could help--avoid plastic, recycle, recycle, recycle, and so on.  A few weeks ago, a warning was sent out from a country's chemical society (never happened before) that minerals used for I-Phones, Computers, and the like will not be available in a hundred years' time.  If we care about future generations we should heed such warnings by recycling, and refusing to buy the latest models.\n \n"
