Can you please try to add sources? The majority of what you're arguing goes against everything I've learned. Also, saying tilling alone turned the Fertile Crescent into Iraqi deserts is absurd. There is myriad evidence of climate change playing a big part in that over the last few thousand years. I'm not saying it didn't perhaps contribute, but stating it's the direct cause is ridiculous. Also, not for nothing, but you're comparing soil recovery times in Saskatchewan (far from ideal growing conditions) to anywhere else as though the less than ideal growing conditions there are a representative sample of conditions worldwide, which is misleading at best.
