Now you’re moving the goalposts. And you’ve moved them more than once already.
First you claimed that it would be sustainable for the over a billion people in India to stay where they were because it’s possible to survive in tundras and deserts.
Then you said that moving them to a place where water exists wouldn’t fix the problem of them dying due to a lack of a water.
Then you asked why water would exist in the new place, which was just a silly question for anyone who understands basic geography.
Now you’re talking about moving all of China, when China wasn’t even discussed.
And at each step, you haven’t gone back to the previous one and acknowledged it was a silly thing to say.
