Should we make more things out of hair, teeth, and nails?

Often I worry if one day we will deplete the world of all its resources. It never ceases to amaze me how much we consume in America. What's more unsettling is how so few of us recycle. Since there are 300 million of us, why don't we make things out of one another after we die. I'm positive we can produce things out of hair. Who says you can't comb the earth for more resources? It may be a hairy situation, but I'm sure it can be brushed over. Why not put more teeth into new technology? It's certainly worth chewing on. I wonder if we can scratch the surface of more innovations, too. I bet we can make some synthetic material out of our nails. Any thoughts on this?
