These activities are constantly changing the type of tree growth in the forest.
Our original forests which bordered the Atlantic coast line when America was first settled, were dense and impenetrable.

The colonists feared the forests because they sheltered the hostile Indians who lurked near the white settlements.

In time this fear of the forest developed into hatred of the forest.

As a result, the colonists cut trees as rapidly as they could.

In every way they fought back the wilderness.
