Lesson 4 : Nature And Agriculture

We can “save the Earth” if we decided to, as proved by the fact that someone already has. Quite a few are working on the problem we face in climate change, species extinctions and efforts for peace but we need much more clarity at to what’s needed and the involvement not of a tiny minority but of a great majority. Crucial in such an enterprise would be building ecocities. Visions are needed as well as understanding life support systems on a grand scale. Major decisions need to be made such as do we give priority to exploration of outer space or the inner space of the human heart and the grounding of future dreams of ways to build and live here on the surface of a healthy Earth? Good idea for appropriately large projects embracing the enterprise of “saving the Earth” are needed and many examples are provided.
