The roots of the modern environmental movement can be traced to attempts in nineteenth-century Europe and North America to expose the costs of environmental negligence, notably disease, as well as widespread air and water pollution, but only after the Second World War did a wider awareness begin to emerge.
The US environmental movement emerged in the late nineteenth and early twentieth century, with two key strands: protectionists such as John Muir wanted land and nature set aside for its own sake, while conservationists such as Gifford Pinchot wanted to manage natural resources for exploitation. Among the early protectionists that stood out as leaders in the movement were Henry David Thoreau, John Muir and George Perkins Marsh. Thoreau was concerned about the wildlife in Massachusetts; he wrote Walden; or, Life in the Woods as he studied the wildlife from a cabin. John Muir founded the Sierra Club, one of the largest conservation organizations in the United States. Marsh was influential with regards to the need for resource conservation. Muir was instrumental in the creation of the world's first national park at Yellowstone in 1872.
During the 1950s, 1960s, and 1970s, several events illustrated the magnitude of environmental damage caused by humans. In 1954, the 23 man crew of the Japanese fishing vessel Lucky Dragon 5 was exposed to radioactive fallout from a hydrogen bomb test at Bikini Atoll. The publication of the book Silent Spring (1962) by Rachel Carson drew attention to the impact of chemicals on the natural environment. In 1967, the oil tanker Torrey Canyon went aground off the southwest coast of England, and in 1969 oil spilled from an offshore well in California's Santa Barbara Channel. In 1971, the conclusion of a law suit in Japan drew international attention to the effects of decades of mercury poisoning on the people of Minamata. [2]
At the same time, emerging scientific research drew new attention to existing and hypothetical threats to the environment and humanity. Among them was Paul R. Ehrlich, whose book The Population Bomb (1968) revived concerns about the impact of exponential population growth. Biologist Barry Commoner generated a debate about growth, affluence and "flawed technology. "Additionally, an association of scientists and political leaders known as the Club of Rome published their report The Limits to Growth in 1972, and drew attention to the growing pressure on natural resources from human activities.
Meanwhile, technological accomplishments such as nuclear proliferation and photos of the Earth from outer space provided both new insights and new reasons for concern over Earth's seemingly small and unique place in the universe.
In 1972, the United Nations Conference on the Human Environment was held in Stockholm, and for the first time united the representativ...
