Thank you for expressing your clear lack of understanding of the issue.

Animals migrate, I understand it might be hard for you to know this as, given your statement here, your education is lacking, but they will always migrate somewhere where they can survive.

And, wouldn't you know it, humans can migrate too.

Also, given your statement indicating a clear lack of knowledge on the matter, the earth was objectively warmer prior to the snow age we're still in, and just because the snow age is ending doesn't indicate that life is going to end, it means anything that's not resilient enough to survive the changes will end, and everything else will continue as normal.

It would behoove you to educate yourself on topics before you talk about them.
