Making compost is gratifying and wonderfully filthy, since it turns garbage into gold. Food waste, yard waste, and even human waste can be made into compost that boosts the fertility of gardens and farms, removes biodegradable matter from landfills, and helps reduce climate change. It’s a winning trifecta.
How can funky, mucky compost help us build a better climate? Let us count the ways:
- Reducing food waste: Composting helps reduce the amount of food waste and green waste headed to landfills. Both food and green waste breaks down into methane, a potent greenhouse gas. NRDC says that the average American wastes 40% of food grown and produced each year. Learn more about food waste here.
- Compost reduces the need for water and synthetic fertilizers: A healthy, compost-rich garden or farm can improve moisture retention, saving water and reducing runoff. Beneficial microorganisms and nutrients within the compost will ensure plant health by boosting nutrients and deterring pests.
- Compost can build and maintain healthy soils: Due to monocropping, over-application of pesticides and other agricultural missteps, soils around the world are being depleted of their natural components. Compost can help bring balance and restore farms and fields to a healthier state. Compost also functions as a major carbon sink: compost adds carbon back to the soil and, with increased plant growth, pulls more carbon from the atmosphere in a virtuous cycle.
- Compost is FREE and EASY: Like most of our Actions, composting is accessible to everyone, whether you’re a townie or living off the grid in the forest. Compost can be as complicated as a DIY compost bin for a big yard, or a small worm compost bin for your apartment balcony. Many cities offer green waste and food waste collection too, making it easier than ever.
