OVERPOPULATION AND OVERCONSUMPTION: WHERE SHOULD WE FOCUS? An NPG Forum Paper by Michael G. Hanauer WE HAVE SO MANY CHOICES There are many pieces to our environmental perhaps because these are the problems we each see in puzzle, which when assembled can ensure that our our own backyards. To those with a more overarching planet and everything on it have a joyful ride now and view, consumption and population issues stand out into the indefinite future. We call that sustainability, because they are largely local and because they are and this is our work, our goal and our passion. But that causal, that is they occur at a community level and tend sustainability can and must be achieved without each to underlie or exacerbate many individual problems. of us manipulating all of the puzzle’s pieces. Each Both of these pieces are important to our ride toward of us must decide which pieces to focus on – which sustainability. Where should we place our emphasis ones we feel are overarching in their effect, which and our resources? ones we as individuals and organizations can impact, and which are most overlooked. In science, there is HOW DO WE CHOOSE FROM a rule of thumb called the 20-80 rule which says that THE CAUSAL TWO? 20 percent of the underlying problems often cause 80 There are many widely read books with titles percent of the significant effects. To be successful in like Fifty Easy Ways to Save the Earth. Almost all of the longer term, an individual or organization needs these books approach issues from the point of view to choose carefully. of reducing (over)consumption. We often hear how the U.S. has 5 percent of the world’s population, 20 percent of underlying problems yet consumes 25 percent of its resources. It’s also cause 80 percent of significant true that the developed world, with 23 percent of the population, uses about 66 percent of the Earth’s effects. resources. Yes, it can sound like just a consumption problem, but the magnitude of this consumption Because the United States so severely aggravates actually makes population even more important to so many of the world’s environmental problems, preserving our environment and quality of life! because of our responsibility to set an example for the In many environmental and population circles, world, and because this is my home, I believe that we the traditional thinking dictates that the problem should place a significant emphasis on our domestic in developing countries is overpopulation, while problems (but certainly not entirely). All solutions in the developed world the bulk of the problem is require support and action at the local level, whether overconsumption. This oversimplification, that the you consider local to be a nation, or an individual U.S. has mainly a consumption problem, purveys community. “Think Globally, Act Locally” makes a easy, feel-good answers to many environmentally lot of sense from any perspective. conscious individuals and organizations. Such feel- Much of the environmental movement has chosen good answers are dangerous because they lead to to pursue specific issues such as pollution, forests, incomplete actions by masking the enduring effects global warming, species diversity or open space – of population growth. Let’s explore further. Revised August 2013 Page 2 Overpopulation and Overconsumption: Where Should We Focus? In the developed world, per capita consumption with increasing population, gains from conservation levels are all within the same order of magnitude. Yes, and recycling are likely to be quickly overwhelmed. in highly populated sections of Western Europe and Still, such efforts are an important part of the solution. Japan levels are somewhat lower than ours (often due to smaller and more expensive living spaces, higher Isn’t TECHNOLOGY OUR energy costs, and fewer cars), but not vastly different. ACE IN THE HOLE? On the other hand, most third world consumption Frequently, we believe that technology can solve levels are between 0.5 and 5 percent of ours. This any problem. The inherent fallacy in this approach vast difference is not because these people recycle, is that the greatest cause of new problems is techno- use little plastic or don’t drive a turbo-charged car fix solutions to old problems. Even our present – it is because they have no car, no central heat, no population growth was brought on by technology refrigerator, and maybe no house at all! which prevented or cured disease and allowed large It is this lack of the most basic items, items which gains in food productivity (often by increased use of most of us believe every human should be able to have, fertilizers and pesticides, and cruel treatment of farm which make up most of the consumption difference animals). But, the most important implication here is between the haves and the have nots. In the developed that technology rarely produces lasting solutions, only additional difficult choices and tradeoffs. An example Technology rarely produces is the solar or electric automobile. The batteries are polluting in production and disposal. The solar panels lasting solutions, only additional are polluting to produce, the power generated to charge difficult choices and tradeoffs. the vehicle usually requires power plants, and we still keep gaining more cars. world, even if every effort were made to cut frills and And what about the choices for those power inefficient consumption, these basics still have us out plants?

Reasonable levels of consumption are not involves safety concerns and the problems of spent morally wrong, in fact most of us believe that they fuel disposal, hydroelectric plants and their associated are desirable. We need to allow all of the world’s dams spoil our rivers’ natural beauty and harm wildlife citizens a reasonable lifestyle while at the same time – and raise the question of just how many dams can be heading toward sustainability. This will require a leap built? What about solar, fusion, and power too cheap in consumption for developing countries, a practical to meter?

Today, because of higher population levels, the NIMBY (Not In My Back Yard) syndrome makes it In a broader sense, the idea of reducing consumption nearly impossible to rationally choose – often none can and should incorporate the industrial processes are really acceptable. Almost every choice involves that produce the goods and dispose of the pollutants, leaving something behind in somebody’s backyard. in addition to what and how much is consumed by individuals.

In addition, affecting these Even where new technology or reduced kinds of changes may be done faster than changing consumption might help, consider the following: population trends.
