No, you are completely wrong.
You asked a specific question: what happens if an environment changes and the population hasn't time to move somewhere else. In that case, the population dies. This has in fact happened in the past, we can find evidence for it. But each time that has happened, other populations were able to survive, and thrive in the new environment.
The history of life on the earth is dominated by extinction. Millions of species have gone extinct. In every case, however, other species moved in. There are massive amounts of evidence to show that this took place. This extinction of one species doesn't necessarily lead to the extinction of another species.
If the environment of the entire planet were to change in such a way that no life could survive, it would become a dead planet. That obviously hasn't happened.

Howling about evidence is a conversation stopper, and it never stops to think if the claim could possibly be true -- foreveryoung
