The Greenpeace ship Esperanza sails to the Amazon Reef, near the coasts of French Guiana as part of the "Protect the Oceans" ship tour, an almost year-long pole to pole voyage from the Arctic to the Antarctic – to highlight the many threats facing the oceans and to campaign for a Global Ocean Treaty and Ocean Sanctuaries covering all seas outside of national waters. The Amazon Reef is an underwater treasure and an unique ecosystem already threatened by giant oil companies that intend to drill nearby.
