<P> The number of people who are overweight has surpassed the number who are undernourished . In a 2006 news story, MSNBC reported, "There are an estimated 800 million undernourished people and more than a billion considered overweight worldwide ." The U.S. has one of the highest rates of obesity in the world . However, studies show that wealthy and educated people are far likelier to eat healthy food, indicating obesity is a disease related to poverty and lack of education and excessive advertising of unhealthy eatables at cheaper cost, high in calories, with little nutritive value are consumed . </P> <P> The Food and Agriculture Organization of the United Nations states in its report The State of Food Insecurity in the World 2006, that while the number of undernourished people in the developing countries has declined by about three million, a smaller proportion of the populations of developing countries is undernourished today than in 1990--92: 17% against 20% . Furthermore, FAO's projections suggest that the proportion of hungry people in developing countries could be halved from 1990--92 levels to 10% by 2015 . The FAO also states "We have emphasized first and foremost that reducing hunger is no longer a question of means in the hands of the global community . The world is richer today than it was ten years ago . There is more food available and still more could be produced without excessive upward pressure on prices . The knowledge and resources to reduce hunger are there . What is lacking is sufficient political will to mobilize those resources to the benefit of the hungry ." </P> <P> As of 2008, the price of grain has increased due to more farming used in biofuels, world oil prices at over $100 a barrel, global population growth, climate change, loss of agricultural land to residential and industrial development, and growing consumer demand in China and India Food riots have recently taken place in many countries across the world . An epidemic of stem rust on wheat caused by race Ug99 is currently spreading across Africa and into Asia and is causing major concern . A virulent wheat disease could destroy most of the world's main wheat crops, leaving millions to starve . The fungus has spread from Africa to Iran, and may already be in Afghanistan and Pakistan . </P> <P> Food security will become more difficult to achieve as resources run out . Resources in danger of becoming depleted include oil, phosphorus, grain, fish, and water . The British scientist John Beddington predicted in 2009 that supplies of energy, food, and water will need to be increased by 50% to reach demand levels of 2030 . According to the Food and Agriculture Organization (FAO), food supplies will need to be increased by 70% by 2050 to meet projected demands . </P>
