Canadian Wheat

Rail cars loaded with canadian wheat travel through the Rocky Mountains on the Canadian Pacific railway line near Banff, Alberta, October 6, 2011. Wheat is the most important cereal in the world and along with rice and maize accounts for about 73% of world cereal production. Canada is the world's third largest exporter, producing annually an average of over 24 million tonnes. The world's population will reach seven billion on 31 October 2011, according to projections by the United Nations. While more people are living longer and healthier lives, says the U.N., widening gaps between rich and poor mean more people than ever are vulnerable to food and water shortages.
