Disappointing to see you downvoted on hacker news of all places. Cmon, have some ambition.

A bunch of people here have no idea how bad the water crunch is. The oogala has been overdrawn for decades, and is a major source of agriculture water for much of the west and Midwest.

CO, UT, AZ, CA, NV etc all dramatically overdraw the Colorado river snopack and will have a reckoning soon enough. The west is also prone to mega droughts, making the problem much worse

Building a $100bn pipeline to irrigate the west absolutely should happen. We can pump it with miles of solar power, build enormous desalination plants, dramatically increase agricultural productivity and provide water to fight the heating effects of global warming.
