I have heard the term "biodynamic" and wondered what was involved. Some consider biodynamic gardening or farming as voodoo science and quackery — or simply a scam. Others feel it is holistic, natural way of gardening leveraging mystical forces. The description I like is defines it as organic permaculture with a spiritual twist.
Most environmental activists focus on top down policy changes to combat global challenges like climate change. But to enact real change, we need to look inwards. The environmental challenges we face in the 21st century are outcomes of who we collectively are as individuals. The best ways to help the environment is to better ourselves.
