Mad Agriculture: link

The health of the land, sea and people is one and indivisible. As we do to one, we do to ourselves. As we do to the Earth, we do to ourselves. The modern tragedy of the Earth system is calling us to heal our relationship to Earth and one another. Mad Agriculture is heeding the call.

“The Harvard Forest Schoolyard Ecology Program brings hands-on ecology research experiences to K-12 classrooms across the northeastern US and was actually the brainchild of our film's protagonist, John O'Keefe” People can donate to support the program at this link: https://community.alumni.harvard.edu/give/51710996.
