How do humans spoil the natural landforms? Please tell the answer fast i have exam tomorrow

1)  Humans have been living on different kinds of landforms in different ways.

2)  Life is difficult in mountainous areas. Plains provide much better living conditions.

3)  Sometimes, we waste the resources of land thereby making them dirty.

4)  For example, we use fertile lands by constructing houses, residential complexes etc. We throw garbage on land and water thereby making them polluted and not usable.

5)  We should avoid using such important gifts of Nature in a careless manner.

6)  These resources are not only for us but also for our future generations. Hence, it is our duty to make Earth a better living place for them
