Nature has been growing massive gardens for a pretty long time. I feed my garden with wood chips, grass clippings, coffee grinds or any other bio-matter that I can get for free, because people would have to pay to get rid of it otherwise. I don’t use any fertilizers or pesticides and I don’t water my garden, even when its 90+ without rain for months. I’m mimicking nature and feeding the bugs & bacteria, which then feed my plants. Our gut works the same way, which is why organic gardening is so important.
If we are not interfacing with our planet at the most fundamental level of our existence, how could anything else work properly?
