How did birds survive the environmental changes that have occured on the Earth?

Biology

It was probably because when a area had too much pollution, they could easily migrate away somewhere else by flying, while humans have to stay everywhere. Another reason could've been that birds can adapt to places quicker than other animals.

Hope it helps!
