Petroleum is used in manufacturing a wide variety of materials, and it is estimated that the world consumes about 90 million barrels each day. Concern over the depletion of the earth's finite reserves of oil, and the effect this would have on a society dependent on it, is a concept known as peak oil.
The National flag of St. Kitts & Nevis features green for our fertile lands, yellow for our year-round sunshine, black for our African heritage, and red for our struggle from slavery through colonialism to independence. It also displays two white stars on a black diagonal bar, symbols of hope and liberty.
Red represents the blood shed by the Patriots who fought for independence. The colors of the US flag were taken from the colors of the British flag. At the time the flag was designed, the red did not mean anything in particular. Officially the red in the flag does not stand for anything. Since the creation of the flag many have suggested that the red could stand for different things such as the blood shed to bring about independence or courage, but these are meanings suggested after the fact and never officially attached to it.
