Your not really listening to me here. The damage was done in the period in which populations rose from 3 billion to 7 billion. Any reasonable estimate says we will hit 10billion - that a further 3billion in an already stressed environment. Ecosystems degrade to the point where they cannot bounce back - they permanently change and there is evidence for this in every part of the globe - especially the oceans. You do not seem to understand the significance of the next 30yrs - its absolutely crucial to the survival of humans as a species - and all the evidence suggests that we will not manage it successfully.

That would be a shame; but a logical, natural consequence of our behaviour. I do all I can, personally, to prevent it; but on the other hand I have faith in human science and technology.
I think we will not only survive, but pass into a period of sustainable comfort never seen before on earth, for all human beings. before reaching out to space to expand. My home state is working towards almost total use of renewable energies, for example. And we just dont know what advances will be made in technologies in the next decade or two, although we do know they will be exponential compared with present progress.
Wind Power 'The New Baseload' In South Australia
by Energy Matters

Achieving 20% renewable energy in Australia by 2020 isn't impossible - in fact, South Australia has already blown past that goal courtesy of wind energy primarily, with a helping hand from residential solar panel installations.
According to a report from EnergyQuest, wind power derived electricity generation grew by 24% (300 GWh) in the March quarter, contributing just over 3% of east coast generation; with the highest level occurring in South Australia (942 GWh), representing 31% of the State's grid generation.
"In South Australia wind appears to be the new baseload," says EnergyQuest Chief Executive Dr Graeme Bethune.

An additional 4 % is provided by solar power meaning that over a third of our energy is now renewable We are also trialling hot rocks and wave energy.
Ie we will change the ecosystems back ourselves, not wait for, or rely on, time and evolution. Our abilty to create is just as great as our abilty to destroy. This is already happening on a small scale in places like australia, and will begin in the west where populations are diminishing and technolgy is the most advanced.
As the third world becomes more "modernised", and its own fertility drops to replacement level, as is occuring even now, along the model of population transition theory, they will follow suit.
Ps not all estimates go to 10 billion. There is a lot of different modelling. Some shows the pop falling back to about 6 million by 2100

World population estimates from 1800 to 2100, based on
UN 2010 projections (

US Census Bureau historical estimates (

You are a child of the universe, no less than the trees and the stars; you have a right to be here. And whether or not it is clear to you, no doubt the universe is unfolding as it should.
Therefore be at peace with God, whatever you conceive Him to be, and whatever your labors and aspirations, in the noisy confusion of life keep peace with your soul.
With all its sham, drudgery and broken dreams, it is still a beautiful world..
Be cheerful.
Strive to be happy.
