What would you do with out your synthetic materials? Synthetic materials are man made, so basically you wouldn't have items such as: shoes made out of synthetic materials, water bottles, and phones, etc...
Compare the man-made items on the left, then look at the non-man-made items on the right.
Where on earth is our stuff, this is all natural stuff there is not 1 man-made item.
If there wasn't any synthetic materials in the world, how would you live? How would you survive the night without your secured house.
This beautiful, secured, warm house, compared to that log cabin.
Where's my warm, cozy, secured house?!
This is why synthetic materials made life so much more easy. Natural items also help life out by doing a LOT of things. Except you can't have these new items like electricity and stuff.
All of these pictures are pictures of man made things, how would you react if you didn't have any of this?
