			CO<sub>2</sub> is not the only greenhouse gas (GHG). Among others are methane (CH<sub>4</sub>) and nitrous oxide (N<sub>2</sub>O), both of which mainly come from agricultural activities.

			The other GHGs described here are methane and nitrous oxide. In fact, there are a few others such as HFCs (refrigerants).

			Methane is released as soon as there is anaerobic (i.e. no oxygen) decomposition:
