Reversing Climate Change

Reversing Climate Change

 Reversing Climate Change. I’m Greg Martin with today’s Line On Agriculture.

I recently saw an old science fiction movie that showed a future earth ravaged by climate change. That got me thinking about whether we can really do anything about it and that’s when I saw a talk by Zimbabwean biologist, farmer, Allan Savory.

SAVORY: The most massive tsunami perfect storm is bearing down upon us. This perfect storm is mounting a grim reality, increasingly grim reality, and we are facing that reality with the full belief that we can solve our problems with technology, and that's very understandable.

Savory says this perfect storm is the result of a rising population, land that is turning to desert, and, of course, climate change.

SAVORY: Now there's no question about it at all: we will only solve the problem of replacing fossil fuels with technology. But fossil fuels, carbon -- coal and gas -- are by no means the only thing that is causing climate change.

According to Savory something called desertification, a fancy word for land that is turning into desert, is a major problem.

SAVORY: But if you do not look at grasslands but look down into them, you find that most of the soil in that grassland that you've just seen is bare and covered with a crust of algae, leading to increased runoff and evaporation. That is the cancer of desertification that we do not recognize till its terminal form.

More tomorrow on this fascinating subject.
