Re: Extinction and Loss of Habitat


Ted,

Exactly. 

The dinosaurs did die off because of a loss of habitat caused
by a meteor crashing into the earth. It really destroyed the habitat.

Loss of habitat is another way of saying some parts of the world are
changing too fast
for some plants/animals to evolve to accommodate the change.

I think I am also safe in saying this is science.
