Re: Is it fair to ask developing countries to go green?
You are right on! You are the first person to address the real issue! What we call development and what human development should be are not the same thing. If we are saying that the undeveloped countries should just start gobbling up resources this human population of ours will not last much longer! … Read More

What about the irreplaceable species that are being lost through habitat destruction by the growth of human population. I assert that this is a resource depletion that is not thought of typically as needed natural resource for human survival but is essential to the health and future evolution of this planet. How can this be measured and when will humans see and feel this mass extinction effect of the growth. Have the "10 billion number" people added this to their calculation. I think that the calculations have only been done looking at immediate survival resources and not long term sustainability concerns.

I did not mean to disagree with you!

Well said.The "Greenwash" problem is a real threat. It has been done with organics. Free Range livestock need only have access to a small door to the outside that is opened only for short times. This definition is an altered form, (altered by special interest groups),and has lost the spirit of the original definition. We need, some how, to keep special interest out of congress from trying to change the definition of green to suit their needs and keep "Greeness" reliable and measurable. How do we do this?

"Survival of the Fittest" does not dictate that all mutations lead to evolutionary benefit. It could be that Homo sapiens' large brain size could function as the mutation principle to arriving at an evolutionary dead-end, as did the large antler size of the Irish Elk cause its extinction. The extent to which we have the information to understand how our selfish-survival behavior coupled with our intellect, affects the evolution on Earth, is limited by the lack of long-term natural history of our species (and funding). Hopefully, we have a couple more million years to learn how to sufficiently extend life and stop causing mass extinction.
