The effects of human population size on our standard of living, our environment, and our prospects for long term sustainability

Our Society Is Not Sustainable by Brishen Hoff

Our society is not sustainable. Our goal is to grow the GDP from one year to the next. GDP is the total dollar value of goods and services consumed. So our goal is to consume an ever increasing amount of goods and services on a finite planet. This is outrageous! Opening a new landfill, building more houses, spilling oil into the ocean, building a new mall with parking lots on farm land, manufacturing cars, etc all serve to grow the GDP. Size of economy or GDP = (# of people) X (average person's consumption) The more people there are, the more economic activity, the higher the GDP. Because resources per capita declines as the number of people increases, I think GDP per capita is quickly becoming inversely correlated with GDP. The more people there are, the poorer each person becomes on average (of course this doesn't affect the major CEOs atop the economic growth pyramid scheme) One way the Canadian, US, Australian, UK, etc governments have been trying to grow the GDP is to bring in hundreds of thousands of immigrants for exponential population growth. This also brings cheap labour for CEOs. In the USA, a new study shows that immigrants quadruple their greenhouse gas emissions upon arrival: This doesn't seem to bother the CEOs. To further illustrate how unsustainable our society is, in the USA there were more babies born in 2007 than any other year in their history. There was a record 4.315 million babies born in the USA in 2007 which is more than any year of the so-called baby boom. According to the latest WWF Living Planet report, humanity is consuming natural resources 30% faster than the earth can produce them and by 2030 we will need 2 planets. The report says that from 1970 to 2005, global biodiversity has declined by 33%. If you want to live in a sustainable society, you cannot have population growth of any kind. Population growth is simply not sustainable. Humanity is already in ecological overshoot. SOLUTIONS: (If you want to live in a sustainable society...) 1) Do not reproduce and tell others why that is important. 2) Advocate reducing immigration intake so that our population can decline to a sustainable level.

On The Brink Of A New Agricultural Revolution?

An article quoting Dr Brian Keating speaking at the Australian Society of Agronomy Conference under the title "On The Brink Of A New Agricultural Revolution" says:

"In a keynote address to the Australian Society of Agronomy Conference, the Director of CSIRO's Agricultural Sustainability Initiative, Dr Brian Keating, said there is evidence that rates of increase in agricultural productivity are easing both in Australia and overseas."

The .

That doesn't sound like a "revolution"... The article then states that...

"With the United Nations predicting the world population to increase by 2.5 billion by 2050 and with dramatic changes in food consumption patterns associated with economic development in Asia, there is an urgent need to face up to the challenge of doubling food production over the next 50 years."

Uh, huh. World population now about 6.72 billion.

says the world population in 2050 is likely to be:

Median variant: 9.191 billion

Low variant: 7.792 billion

Personally, I'll put my money on the low variant.

How cheery do we feel about economic development in Asia to 2050 and the "dramatic changes" it will bring in food consumption patterns?

We then read...

"We are going to need a 'revolution' in agricultural productivity over the coming decades to meet these challenges - particularly in terms of the efficiency with which we use land, water, nutrient and energy resources in agricultural production," Dr Keating said.

Well, we could be adding a little over a billion people and we could have a food consumption revolution in the direction of eating less animal protein. That's just as probable a prognosis for 2050, isn't it? In that case, productivity might have to increase, but production would not necessarily have to. So I agree with the mentioned efficiencies, but the article doesn't say very much about how Dr Keating thinks they will be achieved, except to say that, "he is optimistic that agricultural science and industry innovation is up to these challenges."

That's reassuring. Since in a world where apalling hunger and mass over-consumption of food exist almost side by side one of the most serious problems is how to distribute food more equitably, perhaps we could also come up with some social policies to deal with this issue. If not, even if we double the food supply by 2050, what's going to prevent a doubling of the number of starving while we get a doubling of the obese at the same time?

Dr Keating might benefit from a reading of The Final Energy Crisis (2nd Ed.), published recently, as he will find that he really should introduce a few more variables into his equations in order to get a more realistic approximation of where humanity is headed this century.
