How to green the world's deserts and reverse climate change Allan Savory 2013- TED

I would like to see the white race take over the entire Sahara desert and north part of Africa, as well as just the southern tip of South Africa (which they should build a 30-foot high wall around to keep out the blacks..). This would finally put the region in peace and prosperity and prevent the influx of blacks and muslims into Europe. In addition, we should restore the Sahara desert back into the lush 'garden of eden' that it was around 6000 years ago. Doing so would help all of Africa, including the native black and animal populations of the southern half of the continent. We should also do this in the American west, to end the droughts in the western states.
