> As global warming progresses, a lot of the seeds that we are used to
being able to grow aren't going to grow anymore, and the land that we
used to grow them on will be turning into a desert.

We can find or develop new drought- and heat-tolerant varieties, like the
tepary bean (Phaseolus acutifolius)[1].

More importantly, we can alter the climate directly though our patterns
of agriculture and horticulture.[2][3]

> Within 50 years there's going to be mass migrations and tremendous
demand for the land that is still viable for growing crops.

FWIW, there's a very interesting talk about that[4] and one of the take-aways
is that we may well see e.g. Bangladesh unilaterally pursuing
geoengineering solutions, not waiting for international consensus.

> GMO definitely isn't the only solution, and it may not even be the best
one but it is one field that we need to deeply investigate and try out if
we want our species to survive with a similar standard of living to what
we enjoy today.

I'm not actually against genetic engineering, I just think we should wait
a few hundred years, until we have a better idea of how life works -OR-
some extra-terrestrial biospheres in which to experiment without risking
Earth at all.

In the meantime, I believe we already have all the biological diversity
we need to tackle the coming challenges already, we just have to
recognize and use it.

In any event, the OP is BS propaganda, not science, eh?

[1] "Phaseolus acutifolius, or the Tepary bean, is a legume native to the
southwestern United States and Mexico and has been grown there by the
native peoples since pre-Columbian times. It is more drought-resistant
than the common bean (Phaseolus vulgaris) and is grown in desert and
semi-desert conditions" https://en.wikipedia.org/wiki/Phaseolus_acutifolius

[2] "Greening the Desert II"

> This half hour video documents the ongoing work of Permaculture Gurus,
Geoff and Nadia Lawton, in the Dead Sea Valley. It begins with the famous
original 'Greening the Desert' five minute video clip, and then continues
into Part II, a 2009 update to the 2001 original.

> When there’s no soil, no water, no shade, and where the sun beats down
on you to the tune of over 50°C (122°F), the word ‘poverty’ begins to
take on a whole new meaning. It is distinct and surreal. It’s a land of
dust, flies, intense heat and almost complete dependency on supply lines
outside of ones control.

[3] "Regreening the desert with John D. Liu" | VPRO Documentary | 2012

> Liu filmed the Loess-plateau in China. He witnessed a local population
who turned an area of almost the same size as The Netherlands from a dry,
exhausted wasteland into one green oasis.

> I talked–actually, the head of the Bangladesh Institute of Strategic
Studies about this (you didn’t even know that existed, did you?). Well,
there is one, it’s quite serious–run by a General, bright guy. I said,
“have you heard about geoengineering?” and he smiled–seraphically–and he
said, “Mmm. Yes. Your question?”

> And I asked the question, “Do you think that this is something the
Bangladesh government might want to do a little bit, before, let’s say,
the US government or the Chinese government?”

> He said, “yes it has crossed our minds.”–and then he stopped talking.

There's a lot of other interesting information in that talk.
