What are some of the results of the depletion of our natural assets?

The depletion of the natural assets by the humans has resulted only in negative effects. As natural assets we can take the water, forests, grasslands, oil etc. With the depletion of these natural assets, the humans have managed to cause incredibly high damage to the natural cycles, to the environment, to the species. The water for example is crucial for the survival of any organism, but the humans don't seem to take that in consideration, so the water is overused, and lot of species end up dead. Also, the extraction of groundwater causes the land to be unstable, as big gap opens up below the surface, so the surface layers often crumble. The extraction of oil uses methods that directly kill off and badly injure any living organism nearby. The forests and grasslands have been converted to agricultural landscapes, so lot of species went extinct or are endangered because they have lost their habitats.
