The Wealth Gap

The stark contrast between affluent and poor societies causes social and environmental stress.

The richest 20% use 86% of the world’s resources.

Leaves 14%  of the resources for 80% of the world’s people to share

Wealth also produces environmental impacts

The population problem does not exist only within poor countries.

Affluent societies have enormous resource consumption and waste production.

People use resources from other areas, as well as from their own.

Individuals’ ecological footprints are huge.

One American has as much environmental impact as 6 Chinese or 12 Indians or Ethiopians. The earth cannot support our consumptive lifestyle.


The U.S., with 5% of the world’s population, uses 30% of the world’s energy and 40% of its resources.

If the world’s population consumed as much as North Americans, the carrying capacity would be exceeded

And if developed nations do not help…

Then these countries may result in greater population growth, and worsening social and environmental conditions.

A profoundly negative outcome for humans and the environment

Prevention of which is not without its challenges…
