The sustainability of human life on Earth in the future is in danger. Human actions are producing many harmful and possibly irreversible changes to the environmental conditions that support life on Earth. This article summarizes major threats to Earth's environment, including global warming, ozone layer destruction, exhaustion of fisheries and agricultural land, and widespread exposure to toxic chemicals. Unless they are overcome, these changes will make human life increasingly miserable and eventually may make Earth nearly uninhabitable for future generations. These threats are caused by patterns of human behavior, particularly over-population and over-consumption. Urgent changes to human lifestyles and cultural practices are required for the world to escape ecological disaster, and psychologists should lead the way in helping people adopt sustainable patterns of living. Specific steps toward that goal are proposed in this and the following four articles.
