That's one of several conclusions reached by University of Nebraska - Lincoln ecologist John DeLong, who has co-authored the first study to quantify the relationship between human population growth and energy use on an international scale.

«Social and economic equality empowers societies to engage in sustainable pathways, which includes, by the way, not only the sustainable use of natural resources but also slowing down population growth, to actively diminish the human footprint on the environment.»

««The arid lands of southwestern North America will imminently become even more arid as a result of human - induced climate change just at the time that population growth is increasing demand for water, most of which is still used by agriculture,» said Richard Seager, Senior Research Scientist at the Lamont - Doherty Earth Observatory and one of the lead authors of the study.

If a large section of the population says that a particular releaser is good and that they look and feel better after using it, then the chances are that you can trust that human growth hormone releaser to be genuine.

The women you see who have absolutely huge muscles are professional bodybuilders, which means they: train for about 4 hours in the gym per day, often use performance enhancing drugs (human growth hormone, steroids, etc.) and are often genetically predisposed to muscle growth (which is rare in most populations).

This single, elegant work raises complex questions — which continue to resonate — about land use, food production, population growth, migration, labor, power structures, and human engagement with the natural world.

However, there are certainly forms of «economic activity» that don't require either human population growth, or increased use of physical resources.

flxible wrote that «running an advanced civilization on solar etc only» can only happen if we «accept that growth must end, in «economic» activity, all energy use, and particularly human population».

Zero population growth reduces demand pressure, less pollution, less resource use, less human conflict, and when there are so many positives and no strong argument that the world needs 12 billion people, it is «case closed» as far as I'm concerned.

Alternatively, we could describe climate change as one aspect of a system of human growth (in population, energy use, resource use, economic activity, etc) and the many ways in which that growth is constrained on a finite planet.

What we need to be careful of is thinking that a majority of our fellow humans agree with us on such crucial issues as the need to slow or even reverse population growth or the need to decrease our use of fossil fuels.

It is therefore essential to understand how energy use patterns affect the growth and structure of the global human population [1].

Using a cross-country data set, we show that human population growth rates are negatively related to per - capita energy consumption, with zero growth occurring at ∼ 13 kW, suggesting that the global human population will stop growing only if individuals have access to this amount of power.

First published in 1975, Worldwatch Reports (formerly Worldwatch Papers) use the best available science to focus on the challenges that climate change, resource degradation, and population growth pose for meeting human needs for energy, food, and livelihoods.

Atmospheric CO2 is likely to increase to around 640 ppmv *, assuming — There will be no global Kyoto type climate initiatives — Human CO2 emissions increase with human population — Global per capita human fossil fuel use increases by 30 % by 2100 (it increased by 20 % from 1970 to today)-- Population growth is estimated to slow down sharply, with population reaching 10.5 billion by 2100 (* Note that this could be lower by around 60 ppmv if there is a concerted switch to nuclear power instead of coal for new power plHuman CO2 emissions increase with human population — Global per capita human fossil fuel use increases by 30 % by 2100 (it increased by 20 % from 1970 to today)-- Population growth is estimated to slow down sharply, with population reaching 10.5 billion by 2100 (* Note that this could be lower by around 60 ppmv if there is a concerted switch to nuclear power instead of coal for new power plhuman population — Global per capita human fossil fuel use increases by 30 % by 2100 (it increased by 20 % from 1970 to today)-- Population growth is estimated to slow down sharply, with population reaching 10.5 billion by 2100 (* Note that this could be lower by around 60 ppmv if there is a concerted switch to nuclear power instead of coal for new power plhuman fossil fuel use increases by 30 % by 2100 (it increased by 20 % from 1970 to today)-- Population growth is estimated to slow down sharply, with population reaching 10.5 billion by 2100 (* Note that this could be lower by around 60 ppmv if there is a concerted switch to nuclear power instead of coal for new power plants)

One of the most important projects humans can pursue is — as Jeff Bezos has argued and committed billions to — to use the resources of space (which are approximately ALL resources in the solar system) to alleviate earth's problems, and the logic of energy and population growth is to shift towards heavy manufacturing in space while Earth is «zoned residential and light industrial».
