My immediate thought every time I hear about water shortage in California is that if they were to kick out the millions of illegal aliens, they’d have plenty of water. They refuse to, so they can be thirsty. Actions have consequences.
Here in the NYC metro area we occasionally have water issues because they’ve built no new reservoirs in decades while importing millions of foreigners to fill every available space.
NY state missed out on much of the shale boom that benefited Pennsylvania because they are afraid of the impact on their reservoirs (which are far north of NYC in the mountains).
