Our agriculture is tweaked for a twentieth century climate. Crops are
failing globally. People are dying. More CO2 doesn't mean more crops, it
means more fires and smoke and less vegetation.

Yeah, but Co2 and "global warming" has nothing to do with it, slash and
burn on rainforests, over farming of the land without replenishing the
necessary nutrients, lack of genetic diversity in the plantings, over use
of pesticides with the accompanying increase in tolerance by "the bugs",
over use of herbicides, lack of clean and ample water supplies, etc. are
what we are looking at ... truth is, with ample water and nutrients, the
sands of the desert would be abundant producers of food ...

Sure....for awhile.....then you're going to have problems.

Already in the central valley of California, over farming and lack of care
to the land has found the ground becoming unsuitable to crops, so then
trees are planted, the ground further degrades and finally ends up in the
production of grapes ... Co2 and global warming have simply played no part
what-so-ever in this grim tale of rape of the land ... greed, corruption,
ignorance, laziness, etc. ... your standard culprits ...

So in the end, the desert will once again be desert....so what's your point?

See, trying to create an artificial ecosystem isn't likely to produce a long
term viable ecosystem. If for no other reason than because it lacks the
necessary natural cycles to deal with the accumulation of undesirable
products. Such as salt, which exists in the water you're dumping there.
Without enough water to pick up that salt and flush it into the rivers and
streams and then out to sea.....eventually you will have excessive salt in
your soil and it's going to impact your ecosystem.

Welcome to reality.

We created an artificial growing environment, but because it lacks the full
depth of a natural system....it can exist only temporarily.
