We don’t have the technology to turn the sahara into farmland, and even if we did, we shouldn’t do it. Deserts are critical habitats, not vast empty waistlands.
Turning them into farmland would wipe out countless species. There’s also a reason little grows there. What we can do, is place solar farms out in deserts. A small fraction of the sahara could power the world. That is within our technological ability. This is where captialism strangles us.
Our food production is just fine. We produce too much. Our distribution system however, is not. It focuses on where the most money can be gained, to hell with everyone else. This is where capitalism strangles us.
We also don’t need to turn salt water into fresh water. We need to manage our fresh water better. Use that tech to clean it, and stop poluting it in the first place with fracking and dumping sewage and replacing lead pipes. And to stop letting one or two conglomarates monopolize them. This is where capitalists strangle us.
The problem is not a lack of resources. We have plenty. The problem is captitalism mismanaging and ruining the plentiful resources we have. By opening up new resources such as “turning the sahara into farmland” or turning salt water into fresh water, we are just giving capitalists more resources to destroy and throttle. And destroying more critical environments. We’re not actually fixing the problems.
