aware? or no?

Bowers' reading of "taken for granted" makes me think of Paulo's reading about connect words and world together. Also, it can be drawn to Kolbert's reading of Anthropocene. Humans from some point in history have escaped from evolution, we invented tools and wrote down knowledge. Still in some point, we started to take things for granted. Then the inventions that are supposed to  help us are actually harming us. (From human ecosystem) So the question I am wondering is, why we are still harming ourselves if we know the things we are using are harming us? Are people aware? Or we just "take for granted"?
