World Population Options

The Path to an Ideal World

It seems that our species is driven to try to attain total happiness, which corresponds to maximum life expectancy. Unfortunately, given limited resources, doing so most severely limits the amount of time that resources will last.

Target for Survival

One way to avert a population collapse due to exhaustion of resources is to hold consumption (the mass consumed per year) constant and convert from using non-renewable resources to using renewable resources so that we are consuming more than 99% renewable resources by the end of this century. Starting at the end of 2010, the annual rate (applied to the fraction that is non-renewable) would need to be at least 5.1%:

Milestones

The following world milestones assume business-as-usual behavior:

2004 Peak growth rate for per-capita consumption and population.
2010 Oil consumption (demand) exceeds supply.
2021 Peak per-capita consumption and population.
2027 Population crashes.

Commentary

Projections of U.S. income and cost of living based on the population-consumption model suggest that last year's recession was a consequence of the world's depletion of resources, and that income will grow just barely faster than expense until the world population crashes.

On health care reform and global warming, our leaders have confirmed that they are capable of only halfway measures to deal with the most critical issues of our time. While it is tempting to blame individuals and alliances, the real problem is that as a culture we value individual power above the survival of all, and some lives more than others based on how successful they are at catering to our basest wants rather than our basic needs.

Perhaps the best world we could hope for is one where people cooperate much like the species in a healthy ecosystem. This will perhaps require siphoning energy from our current efforts into building new relationships, with an uncertain result.

The book "Plan C" by Pat Murphy lays out in great detail how we came to reach peak oil and what we can do to alleviate its effects, especially from the perspective of the United States. Statistics quoted in the book suggest that there is 80% of consumption not accounted for in this site's population-consumption projections which is attributable to global warming carbon dioxide emissions. See the blog entry "Plan C-B."

Key Relationships

The longevity of a population -- how long it takes to deplete a fixed amount of resources at a fixed rate -- is proportional to the amount of resources and inversely proportional to the square of per-capita consumption.

Population is proportional to per-capita consumption.

Life expectancy and happiness vary as the logarithm of per-capita consumption.

These relationships are embodied in the current version of the Population-Consumption model.

Longevity Map

By changing three variables, humanity can potentially determine how long it will survive: minimum life expectancy, maximum life expectancy, and total resources. This is illustrated by the longevity map (below), which shows how long the world's current population would take to consume all of its resources. See Comfort.

Now available: "Lights Out" is a novel that explores the consequences of the resource depletion over the very short term, as a fictional electromagnetic pulse disables technology on the Hawaiian islands.

Recommendations

In an ideal world, life expectancy and population size would be maximized for as long as possible. To do this, all consumable resources must be renewable.

Step 1: Identify, retrieve, and enable the use of new, preferably renewable resources.

Step 2: Reduce (or, ideally, eliminate) growth in the amount of resources consumed.

Step 3: Minimize waste by increasing efficiency and recycling as much of everything as possible.


Analysis of population growth and resource use shows that they are intimately connected.

This site explores the relationship and its consequences for the future of humanity. Among them:

  • A long-lived society depends on a very large or almost entirely renewable and reusable resource base
  • Usable natural resources are being rapidly depleted
  • The world's population may crash in this century without drastic action
  • For a better future, we must learn to reconcile the wants of individuals with the needs of society.
