You raise the point of habitat destruction from global warming This is media hysteria, exaggeration and deception.

The Mediterranean area used to be forested now it's desert.
Where I live there were glaciers within that last 10-20,000 years, now it's farm and ranch country.
etc, etc.

The Mediterranean area was not destroyed, it changed. The forest loving animals moved out and the desert loving animals moved in.

Change is inevitable. Any particular piece of habitat is going to change over time. The question is whether their is another piece of habitat available for those critters to go to. The spot that is vacated in turn will be just right for some other critter that is migrating.

There has to be habitat of all kinds everywhere set aside today to insure that species have locations for migration in the future.

A particular species may become locally extinct, however, somewhere else it will become abundant, as long as there is a somewhere else.

I believe global warming is happening and that human activity is accelerating the pace of change.
