We can't wait for the government to make the changes necessary to solve the ever-increasing warming of the planet and we can't stick our heads in the sand and claim it isn't happening.  We as individuals must lead by example.  We are at 7 billion people on this planet and headed for 10 billion by 2050 when calculations by scientists indicate that a sustainable human population on earth is about 1.5 to 3 billion.  If we don't do something voluntarily now, we are inviting mandatory cutbacks in the future.
