Very dry conditions caused by high atmospheric pressure, deforestation, desertification, overgrazing which rids land of vegetation causing erosion of fertile topsoil, and warming changes due to global climate change.
Erosion i believe is the answer
Your answer is Fault Block Mountains
Fault Block Mountains are created when tectonic plates break apart bed rock. If you've ever seen a picture of Yosemite National Park that enourmous rock is a Fault Block Mountain.

I believe not but it really depends on the person's opinion. On one hand we have further industrialized the world at the cost of deforestation which is good for corporations but on the other hand lots of animals are losing their habitats which is fairly bad.
Hope this helps! :D
