Following are some key events from 1945-2002 in the emergence of an international system for protecting the global environment – and a consciousness of the interrelationships among environment, natural resources, population, development, culture, economics, and politics.

1948 

IUCN: The International Union for the Protection of Nature is founded at Fontainebleau, near Paris; in 1956 it will be renamed the International Union for Conservation of Nature and Natural Resources. IUCN is a unique partnership of governments and non-governmental organizations, will become a keystone of the global environmental community. It is now known simply as IUCN or the International Union for Conservation of Nature. For a number of years, until March 2008, it used the awkward names "IUCN – The World Conservation Union," and then "The World Conservation Union (IUCN)."

First Photos of "Spaceship Earth": The U.S. Lunar Orbiter takes the first photographs of Earth from the vicinity of the moon, revealing the finite and frail nature of the biosphere. As the physicist Fritjof Capra has written, these pictures "became a powerful new symbol for the ecology movement and may well be the most significant result of the whole space program"

1967

Torrey Canyon: A tanker carrying 118,000 tons of crude oil, the Torrey Canyon, is wrecked off Land’s End, England. This is the largest oil spill to date and raises public awareness of hazards to the environment

The Limits to Growth: The Club of Rome, a group of leaders and thinkers from 40 countries, issues this report written by Donella and Dennis Meadows. Based on a pioneering U.S. project of computerized global modeling, it argues that if present population, food, pollution, and resource trends continue, the limits to growth on the planet will be reached within the next 100 years; like the "Blueprint," it calls for a state of global equilibrium and stirs much controversy

Stockholm Conference: The United Nations Conference on the Human Environment is held in Stockholm, Sweden; it results in creation of the United Nations Environment Programme (UNEP); Maurice Strong of Canada chairs the conference and will be appointed UNEP’s first Executive Director.

Water Conference: The United Nations Water Conference, held in Mar del Plata, Argentina, sets a goal of providing clean water and adequate sanitation to all in the world by 1990; this will prove to be far from realistic, but the meeting points attention to the central role of water in public health and environmental planning

1979

Greenhouse Effect: A World Climate Conference in Geneva, sponsored by the World Meteorological Organization, concludes that the "greenhouse effect" from increased buildup of carbon dioxide in the atmosphere demands urgent international action.

Montreal Protocol: A protocol designed to reduce depletion of the ozone layer is negotiated in Montreal under UNEP auspices; it sets limits on production and consumption of certain chlorofluorocarbons and halons.
