Composting is our way of imitating nature. On earth, when plants die, they start to decompose. Microbes, bacteria, and other living organisms (like worms) eat the decaying matter as food. Their digestion turns nature's "waste" into nutrients that plants need to grow!
The soil food web is complex, and it is hard to know how humans fit into it, but we have to learn! Right now, our waste system is linear; this is the opposite of nature. Humans are the only living things on this planet that generate "waste". We can change that in our lifetime by changing the value of "waste" to organic gold (aka nutritious fertilizer).
If we can see waste as a valuable resource rather than as "waste" we can generate a circular food system. This means that most resources are reserved and can be reused and restored through natural processes. We never have to contribute "new" materials into the system (such as inorganic fertilizer, or GMOs), nature takes care of that for us.
One way to achieve this is through composting. Nutrients in our food waste can be conserved and returned to the soil through composting organisms such as wormies! After they process their food, the nutrients they leave behind are absorbed by plants. Plants can grow to be more nutrient rich this way compared to with inorganic fertilizers, which are designed to make things grow fast, not strong.
If we eat more nutritious, local food, we are not only fueling ourselves, but also the soil and the local economy! If each of us composted and used our compost to grow our own food, we could reduce food waste, reduce the use of harmful fertilizers, and we could contribute to the circular food system!
In case you needed another reason to start composting, here is a very catchy song that can get stuck in your head for a week! Enjoy!
