Wrong. Weather patterns are weather patterns. Is Kansas a dust bowl or not? It isn’t. I’m surprised you know there are only 2 genders, because your “science” isn’t anything confirmed. It looks like you are attempting your very best imitation of Anthony “I am the science” Fauci.
I am willing to concede water use is growing too much in the Colorado river basin because the water allocations are based on a nominal water supply and the river is running below that -- and all 7 states are close or above their allocations, so lake Mead is dropping every year. In 2006 the US population, including illegals was 310 million. 20 years later we are up to 350 million and they all drink water.
Some may be yearning for a time when agriculture and ranching had plenty of water. Not going to happen with all this immigration. The birth rate is less than 2, so the entirety of the growth is immigration. If it comes to people or agriculture, the politicians will choose people every time. Maybe we should turn off the immigration spigot.
Finally, the biggest problem with cattle herds is in Texas and Oklahoma, not the Colorado river basin. Lots of factors, incl they use feed to grow the cattle, not just "free" grazing. Trump has fixed some of the regulations but there is no easy fix to change this. It may be that America will need to start importing more of its beef, we already do it with vegetables and flowers.
(I got my wife "fresh" flowers for her birthday at Alberstons recently and they were from South America! Lots of logistics and air freight to get them to market in 3-5 days. But apparently they are lower cost than locally produced flowers.
Edit: I realize that people are moving to the Southwest voluntarily so it isn't just immigration. But an added 40 million in 20 years is a lot of extra people.
