Page 13.

Try it out.

So the people cut down all of the trees. Well, what happened when the people cut down all of the trees?

They disappeared. They died. Why?

There are two main reasons, one result of cutting down the trees was that there was no wood left for making farming tools.

And without farming tools, you have no food. Another effect of cutting down the trees is they had nothing to build houses with and without homes they became cold and sick.

So these two main reasons why these people disappeared.

OK, any question so far?
