Unreferenced date September 2008 World Park Base was a non governmental year round Antarctic base located at Cape Evans on Ross Island in the Ross Dependency . The international environmental organization Greenpeace established World Park Base in 1987 in order to press its demand for the Antarctic Treaty nations to declare all of the continent of Antarctica a World Park. This would make the entire continent off limits to commercial exploitation and pollution, and permit only limited scientific research. Greenpeace closed down and completely dismantled the base in 1992. The official attitude amongst the Antarctic Treaty nations was that World Park Base was to be ignored and that no assistance be given to it, although New Zealand , which claims jurisdiction over Ross Dependency though all territorial claims are in abeyance under the Antarctic Treaty , would have assisted if a life threatening situation arose.

There are coal deposits in Hokkaid and Ky sh close to Nagasaki . Oil wells have been drilled off the west coast of Honsh and Japan has oil concessions in North Sakhalin . Iron is scarce outside of Hokkaid and northwest Honsh , and iron pyrite has been discovered in Honsh , Shikoku and Karafuto . A modest quantity of copper and gold is mined around Honsh , Hokkaid and Karafuto. Due to its abundant rainfall and high mountains, Japan is well placed to exploit hydroelectric power. Japanese used 80 of these energy sources in Asia but only possessed a small proportion of its total of energy sources. Industrial Coal The main industrial coal found in Japan in abundance was not adequate for heavy industry. Production in Japan was 55,000 tonnes. Additionally, Japan obtained other industrial quality coal from Korea , Manchukuo and the Occupied China mainland. Their iron production was low just 2 of the United States regular iron extraction, bolstered by iron pyrite production where Japan had 6 of the world production. There was very little extraction of petroleum. The Japanese generated 8,000 megawatts MW of hydraulic energy, favourably comparing with American electric energy production, and was a valuable energy source for their industries, in particular for textiles.
