Known for obstructing Japanese whaling activities in the Southern Ocean since 2005, Sea Shepherd Conservation Society is a Washington-based marine conservation organization with direct action tactics to save the oceans. Founded by Paul Watson, a former member of Greenpeace, in 1977, under the name Earth Force Society, the organization is involved in a number of 'controversial activities' to protect the ocean and marine life. Sea Shepherd Conservation Society carries out operations that involve direct, non-lethal tactics including scuttling and disabling whaling vessels, intervening in seal hunts and throwing bottles of foul-smelling butyric acid onto whaling vessels at sea, among others. As a response to the organisation's effort, the Japanese government has called Sea Shepherd eco-terrorists for impeding their research. They are active in many regions of the world, including North America, the Caribbean, Europe including Italy, Asia, Australia and New Zealand.
