Population, Consumption and the Future

As the world population grows toward 10 billion, consumption of water, food and energy is expanding at a rate that cannot be maintained without depleting the planet’s resources. If we fail to address these two issues together, we face a grim future of economic, social and environmental ills, warns a new report prepared by a group of scientists and other experts for the Royal Society.

The report “People and the Planet,” published this week by the London-based society, examines trends in population and consumption and points to some stark realities:

  • While population increase has been declining since the mid-1960s, experts project we will still add 2.3 billion people by 2050, much of it in increasingly crowded cities.
  • Along with an increasing demand for basic needs, the gap between the haves and the have-nots is striking. For instance, the report says, “a child from the developed world consumes 30-50 times as much water as one from the developing world.” By 2025, the report says, 1.8 billion people could be living in areas where water is a scarce commodity.
  • A similar gap holds for food and energy: While average consumption of calories has increased, in 2010 “close to one billion people did not receive enough calories to reach their minimum dietary energy requirements.” Per capita emissions of CO2 “are up to 50 times higher in high income than low income countries, with energy insufficiency a major component of poverty.”

“The world now has a very clear choice,” concluded Sir John Sulston, a fellow of the Royal Society and chairman of the report’s working group. “We can choose to address the twin issues of population and consumption. We can choose to rebalance the use of resources to a more egalitarian pattern of consumption, to reframe our economic values to truly reflect what our consumption means for our planet and to help individuals around the world to make informed and free reproductive choices.  Or we can choose to do nothing and to drift into a downward vortex of economic, socio-political and environmental ills, leading to a more unequal and inhospitable future.”
