Happy World Overshoot Day!

Renewable energy. 3-D printing food. That will take care of it. SCIENCE!

This!

Luddites deserve the rope.
Condemning all the rest of us to scarcity.

I think 3D printing of food will be the greatest health and environmental development of this century. I typically go here: http://3dprinting.com/food/ to read about it.

[The Minsky Moment]

I don't understand.  There are so many different types of resources.  Timber, oil, coal, fish, you name it.  I don't see how a single number can represent them all.  In this decade we use lots of oil but less coal.  In the next decade we switch to uranium.  How can that number reflect these changes?

It's a PR exercise.
Not to say there is no underlying problem.
