Planet Health

It was the Christmas of 2009. My brother gave me a book as a present, whose picture you can see below. I loved that book so much that I participated in the Human Document Project in 2010. That is another story, and shall be told another time. Today, I would like you to understand the concepts presented in this book.
James Lovelock formulated the hypothesis of Gaia, which proposes that organisms interact with their inorganic surroundings on Earth to form a synergistic self-regulating, complex system that helps to maintain and perpetuate the conditions for life on the planet [Wikipedia]. In order words, a new vision about out planet Earth, considering it as a self regulator system.
Gaia for me was the idea of considering the Earth as an alive system. When I read this book, whose original title is "The Revenge of Gaia: Why the Earth Is Fighting Back", I discovered this vision of the climate change as never heard before. If we considered Gaia's homeostasis, maybe the fate of humanity could be less devastating by providing some positive feedbacks into the system.
There is a wide room for discussion here. In my opinion, you should read this book if you are really interested in global warming, future of human kind and the planet Earth.
However, the topic of my post today focuses on the idea of planetary health. Let's called it Gaia, or Earth, at the end the question is: how can we diagnose the health of our planet, and what are the measures to "cure" it?
The Rockefeller Foundation–Lancet Commission on Planetary Health was launched in 2015, and its mission is to take care of that.
I invite you to read more in the foundation website, and also a general article about planetary health can be found HERE.
