Composting is not just for gardeners.
It is a climate change reduction strategy.

Americans generate more waste than any other nation. In 2010, the US produced 34 million tons of food waste and another 14 million tons of yard waste. Organic waste is compostable.  In a natural setting, the aerobic process of decay releases sequestered nutrients back into the earth. However, most modern waste is processed in an airless landfill. Food scraps, yard waste and  paper products cannot decompose without oxygen, and the anaerobic decay from buried waste produces a greenhouse gas called methane.  Every time a banana peel or cardboard box goes into the landfill, more toxic gases are produced. 

Composting is a sustainability strategy which benefits the environment, the economy and society. However, a cultural shift is needed before communities, schools and businesses embrace source separation as a way of life. There is already a national movement to support organic agriculture and green infrastructure, yet  the status quo of waste management remains unchallenged.  Activists are needed to make compost second nature.
