"Your idea of zero footprint deserves debunking. I had implied that with my habitat displacement comment early on. No biologist or ecologist I know of would agree with your claim. It is widely known in the life sciences that humans are a "Patch…"
"And when the rate of growth reaches zero, the growth also reaches zero.
So you seem to agree, as I do, that population growth has declined due to environmental pressures, but the story will be different as we increasingly eliminate our…"
"Unlimited energy, by itself, would be a problem, especially if it is inherently dirty. That is essentially the problem with fossil fuels in the early days when it appeared to be an unlimited supply. We would be a lot better off if the…"
Sure the RATE of growth is slowing. Attrition includes myriad feedback loops including reduced fertility, both intentional and not. (chemicals lowering sperm counts, malnutrition lowering fertility, etc) But when a species is in hundreds of…"
"If the energy you claim is available, then there is a quote you should see:
Stanford biologist Paul Ehrlich: If we were to tap cheap, inexhaustible energy, he said, it would be "like giving a machine gun to an idiot child."
"Well, I can say the same. You haven't replied to my points, except to be merely dismissive, which is not an argument. Not helpful.
Most of what I said in my reply was in direct response to your claim that "Every human, no…"
"I believe it is essential to understand our relationship with the environment in terms of whether we are net positive or negative. How can it not be so?
I don't mean that we should consider this in isolation, as if we are just…"
"You haven't replied to my points. Also, you obviously believe that homo superstitious is capable of behavior unlike anything evidenced in thousands of years to date. I wager on future outcomes for charity at
"Do you believe it is impossible to achieve the goal of Zero Footprint? I suspect you do, and hence people become a problem just by the numbers. But it is relatively simple to show that we can achieve Zero Footprint, and we must do so if…"
"Huge problem for whom? ;-) Every human, no matter how simply she lives, displaces habitat for other life forms except human parasites and those that thrive on our waste. A robust, diversified biosphere provides the best long term habitat for our…"
I'm unsure if classifying resource usage as being net positive or negative is the right approach. In our lifetimes we will leave some resources depleted (breathe in oxygen) and leave others more plentiful (breathe out CO2). A…"
