"Normal" Design Life Cycle Assessment, what its doing

Prime to what I think the normal design principles are. We can change this for the better through sustainable design and this life cycle of resources and products can be avidly changed for the better as long as we stick firm to our choices when using the principles behind our backs.

All the negative things that the normal design principles create can be changed but without the humans help, this can really go nowhere so im hoping in my essay to show what this life cycle is doing to our environment.
