I imagine the same thing happened in large parts of the U.S. and now it's a Ag superpower.

One day, perhaps, we'll meet all our needs with indoor hydroponics and let the land return to its natural state.

Need to manage it well so it isn't completely destroyed in the meantime.

For the near future this will be a huge boon to the Brazilian economy and global food supply.

Unless we start building tons of fission plants or "solve" fusion power, 95% of our staple crops will be more efficient to grow directly with the sun. So maybe indoor in a greenhouse sense, but not an artificially lit warehouse.

The only plants that need less sun are shade tolerant herbs and leafy greens which are already a very tiny portion of our agricultural land usage.

Thanks for the reality check. Urban vertical farms are such a great visual, but you are right, obviously they can't compete with actual staple crops on vast farmlands.

I wondered about growing crops in space with endless solar power.. the next frontier in monetizing access to space? Where would the elemental inputs come from? Not much C, O, N, or H to go around.

Just another raspberry pie in the sky for now..

Interesting reading about developments in space farming tho.

I see a good use of hydroponics, growing herbs indoors. Every kitchen having something the size of a fridge, for growing things like fresh basil, and sage.
