“Each of the global problems we face today is the result of too many people using too much of our planet’s finite, non-renewable resources and filling its waste repositories of land, water and air to overflowing.” Business Insider quotes Paul Chefurka (Population: The Elephant in the Room). “The true danger posed by our exploding population is not our absolute numbers but the inability of our environment to cope with so many of us doing what we do. It is becoming clearer every day, as crises like global warming, water, soil and food depletion, biodiversity loss and the degradation of our oceans constantly worsen, that the human situation is not sustainable. Bringing about a sustainable balance between ourselves and the planet we depend on will require us, in very short order, to reduce our population, our level of activity, or both…. Populations in serious overshoot always decline. This is seen in wine vats when the yeast cells die after consuming all the sugar from the grapes and bathing themselves in their own poisonous alcoholic wastes. It’s seen in predator-prey relations in the animal world, where the depletion of the prey species results in a die-back of the predators. Actually, it’s a bit worse than that. The population may actually fall to a lower level than was sustainable before the overshoot. The reason is that unsustainable consumption while in overshoot allowed the species to use more non-renewable resources and to further poison their environment with excessive wastes. In the case of humanity, our use of oil has allowed us to perform prodigious feats of resource extraction and waste production that would simply have been inconceivable before the oil age. If our oil supply declined, the lower available energy might be insufficient to let us extract and use the lower grade resources that remain. A similar case can be made for a lessened ability to deal with wastes in our environment.”
