NORTH AMERICA

• Canada now ranks in the top three diamond producers in the world (in terms of value) and North America is the second largest oil producing area after the Middle East

• North America is the third largest continent in area and is fourth in population, with 74% of its population living in urban areas

FAO 2005; UNEP-GEO3; USDA 2005; Wikipedia

• In the United States there are 155 national forests (protected forests and woodland areas) containing almost 190 000 000 acres (769 000 km2) of land that comprise 8.5% of the total land area with Alaska alone accounting for 12% of all National Forest land

• North America holds about 13 per cent of the world's renewable freshwater (excluding glaciers and ice caps)
