JAKARTA, Nov. 10 (Xinhua) -- Greenpeace activists on Monday prevented shipments of tens of thousands tons of palm oil from departing from Indonesia to Europe, as a protest against the ongoing destruction of Indonesia's rainforest, an activist said.

    The activists hanged on the chains of the anchors of three ships which are scheduled for departing on Monday, at the Indonesia's main export port of Dumai in Riau province, Forest Campaigner Greenpeace Southeast Asia Bustar Maitar said.

    Two of the three ships were loaded with over 27,000 tons and 2,600 tons of palm oil, he said, adding that all the ships are still at the port.

    On their action, the activists painted the ships with the words "Forest Crime and Climate Crime" on the hull of the three palm oil tankers, Maitar said.

    "Today Greenpeace is taking action to expose the disastrous impacts of the palm oil and logging industries on Indonesia's peatlands, forests and on the global climate" said Maitar.

    Indonesia along with other tropical countries is homed to twenty percent of the world's forest.

    The Indonesian government has struggled against the problem by planting tens of millions of trees and implementing strict law enforcement.

    The archipelago country has also mobilized other countries including Malaysia, Brazil, Congo, Cameroon, Costa Rica, Gabon, and Papua New Guinea, in a move to protect their rainforests.

    Indonesia is the biggest palm oil producer.

    The action is the second time carried out by the organization, as it blocked shipment of the palm oil last year at the same port.
