Ecologist Says Unchecked Population Growth Could Bring Misery

David Pimentel, a Cornell University professor of ecology and agricultural sciences, sees several possible scenarios for the 22nd century: A planet with 2 billion people thriving in harmony with the environment; or, at the other extreme, 12 billion miserable humans suffering a difficult life with limited resources and widespread famine. Pimentel says the next century is crucial because the human population could pass sustainable limits.

'We must avoid letting human numbers continue to increase and surpass the limit of the earth's natural resources and forcing natural forces to control our number by disease, malnutrition and violent conflicts over resources,' Pimentel writes in his report, 'Will Limits of the Earth's Resources Control Human Numbers?' which appeared in the first issue of the journal Environment, Development and Sustainability.

Pimental says the only way to manage the earth's population is to reduce the number of children per couple. He estimates that if people average 1.5 children per couple, the optimal earth population of 2 billion could be achieved in 100 years. Even slightly more children per couple will make the earth's number's swell in short order: 'If we adopted a policy of 2.1 children starting tomorrow, the world population will continue to increase and 60 years from now we will have close to 12 billion people,' he said.

Pimentel says that in order for every person on earth to have adequate resources of food, shelter and clothing, the ideal population on the earth should be about 2 billion -- approximately the number of people living on the planet in the 1950s. These fortunate 2 billion will be free from poverty and starvation, living in an environment capable of sustaining human life with dignity, the report suggests.

But even at a reduced world population -- achieved, ideally, by democratically determined population control practices and sound resource-management policies -- life for the average person cannot be as luxurious as it is for many Americans today, with a standard of living about half of that in the United States in the 1990s, or the standard experienced by the average European today.

In addition to reducing the earth's population, cropland needs to be preserved, and water and energy must be conserved, Pimentel says. 'None of these solutions, unfortunately, will be painless,' Pimentel points out. While Pimentel holds some optimism that if people recognize the problem there will be a movement toward a solution: 'But the question is, when will we recognize that this is a problem? History dictates that we humans never get at a problem until there is a crisis.'

Pimentel concedes that the findings of the report are disturbing: 'I found that it's a lot worse than I had anticipated. I have children and grandchildren and, unless something is done, the future doesn't look too bright,' he said.

Hydroponic Mid-Ocean Tomatoes- In light of land concerns, the answer is boats (ships, really) to grow a percentage of our crops, in the dead zones of the sea; hydroponic with an airtight seal could mean the water could be reused instantly. I believe in NASA and future interplanetary travel, but what if lots of planets have a high water to earth ratio? This solution could perhaps be useful forever.

It is true there are so many people.

According to Donella Meadows the next "revolution" will be the sustainability revolution (Limits to Growth: 30 year Update, 2004). The difficulty lies in deciding what "sustainable" ought to be. I present a possible solution to this problem at: Universal Platform for Developing Sustainable Earth Vision Co-operatively. http://www.modelearth.org/seed.html Thank you, Hearthstone.

David Pimentel and I co-authored a paper in 2001 addessing the underpinnings of human popualtion growth. You can find it at http://www.PanEarth.org -- just go to the "publications" section. When addressing any ongoing and seemingly intractable problem or difficulty, it is vital to have an understanding of the root causes. The variables governing human population dynamics are no different than those governing the population dynamics of any other species. Please go to http://www.PanEarth.org and see the narrated slide show.
