A variety of processes, including farming, cropping, transportation, natural waste, animal waste, cooked food, and others, result in the production of agricultural and food wastes. When these wastes are disposed of in landfills, they decompose and produce a variety of greenhouse gases that fuel global warming. Composting is the best solution because it improves soil nutrition, lowers greenhouse gas emissions, and yields biofuels and bioenergy. The environment is kept healthy for farm animals and crop production through proper waste management.
