For my canadian history assignment why did groups such as pollution probe and greenpeace form? what are their main objectives?

Pollution Probe was formed in 1969 by a group of University of Toronto students concerned about some environmental issues that had no defense at the moment. In this time is a national nonprofit, nongovernmental environmental organization, its mission is to achieve tangible and positive environmental change.

Greenpeace was founded in 1971 by Irving Stowe and Dorothy Stowe, Canadian and US ex-pat environmental activists. They began with the concern of the US nuclear testing in Alaska and were called, "Don't make a wave committee". In this time is an independent, nonprofit, global campaigning organization that uses non-violent confrontation to expose global environmental problems and their causes, this to create a positive change through action to defend the natural world and promote peace and confront environmental abuse by governments and corporations around the world.
