If it takes 100 or 200 years, we'll still have war.

There is an argument to be had that many of the wars we've seen over the past 25 years, have already been at least in part rooted in access to water. Billions more will get impacted like that over the next century, with tens of millions of migrants a year, every year fleeing from both war and unhabitable conditions, for the next 100+ years.

We've barely seen the beginning of it.
