Like always leave it to Japanese to find the solution. They have found a way to turn poo into edible meat.

I love how the solution is spelled out so clearly...oh wait
This is like saying "we need to develop a warp drive to fly to other stars, so come one science, do it already."

I think Bill Gates is probably one of the greatest people on this planet. Forget Microsoft, what he's done and is doing with their foundation is make a real difference to lives all over the world. I have nothing but respect for the man.

HOw is it a problem?
We shat in the woods for milleniums...
The problems began when we invented the toilet, and plumbing and suddenly all the shit gathered at the same place...
Just poop in the woods!
