How is a compost pit environmentally friendly to the world?

Breakdown of organic materials, cost minimization, resource maximization, and sanitation are ways in which a compost pit is environmentally friendly to the world. A compost pit is an example of composting through alternately layering carbon- and nitrogen-rich materials in a hole in the ground. It saves on money otherwise spent for soil amendments, fertilizers, and mulches and on time spent on transporting food scraps and yard debris to landfills.
