Composting is not talked about a whole lot, even by environmentalists. Perhaps this is because few people enjoy spending time with their garbage (which is understandable). But composting is just as important as recycling, only it is "recycling" organic trash. Instead of TVs and plastic bottles, it is recycling lettuce scraps and moldy bread. Composting reduces the mass of garbage that will end up in the landfill, and it also keeps the organic matter in circulation. When organic trash goes to the landfill, it may take years or even decades for the matter to decompose and return to the earth. When composted, however, it is returned to the earth in matter of days.
===Energy Savings===
This issue is last because it is least important. The main reason we are told to save energy is to create less CO<sub>2</sub>, but since man-made global warming is by no means proven, CO<sub>2</sub> emissions are not that big a deal. The other reason for saving energy is that fossil fuels are for the most part nonrenewable. We will almost certainly have discovered sustainable renewable energy sources by the time fossil fuels run out, however, so saving energy is good, but is far less important than the other issues outlined.
