Allan Savory—Halting Desertification

June 13, 2015 by Immanuela Meijer

I don’t know what to do about climate change. Don’t stop reading! I promise this won’t be yet another depressing article about something many of us feel powerless to stop.

Increasing numbers have noticed environmental differences and much of the public’s focus has been on trying to establish the cause. There are some folks who argue that it’s manmade and irreversible now, and others who assert that the irregular weather patterns are part of the earth’s natural, cyclical phases over eons. To me, the why of it is moot. It’s clear that big changes are underway either way.

My concern is how life, with its many human and non-human members, is going to cope with the altered environment, and as such, I am always delighted to see viable, reasonable solutions offered for the some of the challenges that we may face. Check out the TED Talk by Allan Savory below. Clean water, sustainable food production, desertification, and preserving biodiversity are already pressing issues. His proposal tackles all of these:

The surface of Venus is an uninhabitable mix of corrosive chemicals and annihilating pressure. Fifty kilometers above, however, the atmosphere provides protection from solar radiation, milder temperatures, and the pressure is nearly equivalent to Earth’s, unlike on Mars. Dense levels of carbon dioxide in the upper reaches of Venus’ toxic atmosphere would keep an air-filled blimp city afloat. Several sections of the colony could be dedicated arboretums, atmospheric and human byproduct carbon dioxide consumed by the trees while they pump fresh oxygen out. A city of trees in the clouds.Continue Reading
