"There is definitely a controversy between whether or not Global Warming is happening or not . I know that where I live , the year-round temperature is actually getting colder ! Anyway , even if Global Warming was a proven fact , nothing should change . We should still be trying to create as little pollution as possible , right ? So , what does it matter ?"
"Because global warming changes what we consider to be pollution . CO2 emissions are only really a pollutant because they contribute to climate change , because the levels for CO2 to be toxic to humans are order of magnitude higher than those presently in the atmosphere ."
