We Need Better Planet Management Skills
The first thing we should do is to start saying to ourselves and our children: “We live on a planet that is a spaceship with limited supplies.” The human passengers have to live off the supplies of our spaceship has grown too large and too rapidly. There were 800 million people in 1800, 1.8 billion in 1900, and 6.5 billion in 2000. There will be perhaps as many as 12 billion of us in 2100. We humans are big eaters and garbage producers. We are starting to be in serious trouble as result of all the resources we consume. An even larger problem is all the waste that we are producing in the form of greenhouse gases that we cannot easily offload into space.
