Climate Change: The Water Paradigm

Climate Change: The Water Paradigm

In this video, we explore why maintaining a healthy water cycle may be much more important for the health of the climate than people realize. In case you are wondering, I'm not suggesting that the greenhouse effect due to CO2 or methane is insignificant. But I do think that the importance of the water cycle has been grossly under-emphasized, and should occupy a more central position in environmental discourse.

What is Regenerative Agriculture?

Regenerative agriculture is an effective way to restore biodiversity and stabilize the climate, but what exactly is it? This video explores three different regenerative practices that have great potential both in food production and in healing the land.
