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
• 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 is the third largest continent in area and is fourth in
population, with 74% of its population living in urban areas
• North America holds about 13 per cent of the world's renewable
freshwater (excluding glaciers and ice caps)
