I need a better name for this, but this is a project I was daydreaming about today: the Human Constraint Project. The goal is to form a group for the massive reduction in human population in a healthy way (psychologically, sociologically, intellectually). It is perhaps unrealizable, but you can never tell what you can accomplish until you try. It would be a group dedicated to studying ways in which one can get humans to voluntarily massively reduce their numbers in a peaceful, constructive way that greatly increases both the standard of living and the standard of living for the rest of the ecosystem.

Over-population is the one problem which, unless it is tackled, all other problems are unsolvable (global warming, despeciation, deforestation, pollution, etc).
