How do humans shape the world in which they live? 

 

Humans change the world to make it more comfortable for themselves, unfortunately this is not good for earth. Humans change the world driven by their needs, or most often, wants. Due to man kinds greed, everything suffers. We have left our mark not only on earth though. The real question should be WHY people change the world, not how. People have become so smart and powerful, that, if they felt like it, they could literally shape the world, like play dough.
