The Organization for Economic Cooperation and Development (OECD) has 30 member states and Korea ranks #1 in terms of energy used in proportion to the Gross Domestic Product (GDP). Not only that, but also the quantity of carbon dioxide emitted by the country is at the top of the list.
The environmental evaluation report was done from 1997-2005. Korea uses more energy per GDP unit than the United States.
The report singles out excessive amounts of: water usage, chemical fertilizers and pesticides.
Korea is a very polluted country. This is not to say that Canada and the United States are not polluted - because they are - but Korea is a small country, with little arable land and pollution will utterly destroy this country.
