CO2 must be causing some form of pollution as it is the biggest contribution humans are releasing into the atmosphere. There has to be a reason why global warming is happening. LaurenAL (talk) 18:54, 16 March 2012 (UTC)[reply]

Humans may not be completely to blame but they are definitely contributing. CFC's are proven to contribute to global warming and have already been banned. We (humans) are still producing N2O and N2O, once it reaches the stratosphere, releases ozone depleting chemicals. The human population still needs to reduce the amount of damage we are doing considering that the earth naturally contributes to this as well. --Randana (talk) 00:19, 11 April 2012 (UTC)[reply]
