I have a mild form of it - I recognize family and friends, but I will not recognize an acquaintance on the street even if I've met him or her ten times before. I also mistake unknown people for acquaintances.
There is an interesting counterpoint to the disability - some people are "super recognizers" and can identify someone instantly that they've met (or seen) only once twenty years ago. All traits lie on a bell curve, I guess.

So, assuming you can plant trees in the desert, napkin calculating with figures from the linked article and assuming that drip irrigation of trees requires 4 m3/acre/day, this would need 60 000 new desalination plants and power installations delivering 2x12 TW/day (2x b/c night production is 0, otherwise assuming 100% efficiency). The solar panels would cover around 29 million acres (roughly 1.5x Tunisia, and 170x the current world yearly production of solar panels).
Desal plant cost ~$18 trillion, power plant cost ~$36 trillion. World GDP is ~$80 trillion. I like trees, but one percent of this goal would still be a moonshot project.

3 billion acres is roughly the area of South America. You do realize that finding that much previously unplanted acreage is completely impossible, right?
