In terms of how we affect the Lithosphere, we do many things. Some behaviors are inherently natural, like building places to live. Cities are not necessarily destructive places. If you have 1 million homo sapiens living on 20,000 sq miles of land, is it better to have 50 people on each acre, or a city with 200 per acre, 5,000 acres of farms and 10,000 acres preserving biodiversity?
Homo sapiens is a species which has developed here on the Earth and thus are a natural part of it. We differ only in our ability to understand the changes we affect. There are other species which have exacted larger changes in the planet then we ever could (micro algae in the primordial sea altered an oxygen free environment to one with over 35% oxygen, making the atmosphere explosive!).
As to the changes we make in the lithosphere, consider mining as a biggie. We are extracting resources at an amazing rate and these changes are visible from space! Also, as a sub component to farming, the use of atmospheric nitrogen to manufacture ammonia fertilizer greatly affects the land. It is estimated that half of all the nitrogen incorporated in your body was artificially fixed. The largest pollution problems that exist today are the release of too much carbon from the ground into the air and too much nitrogen from the air released into the ground.

Here is a link to NASA's Earth Observatory. You will find spectacular photos and articles on how man is changing the Earth. Good Luck!

lithosphere: the forged outermost shell of a rocky planet. on the earth, the lithosphere includes the crust and the uppermost mantle. hydrosphere: otherwise commonly used using fact the hydrocycle, it describes the collective mass of water discovered on, under, and over the exterior of a planet. It includes water in it particularly is distinctive kinds and their interactions with one yet another. environment: a layer of gases that could encompass a textile physique of sufficient mass. The gases are attracted via the gravity of the physique, and held speedy if gravity is sufficient and the ambience's temperature is low.
