Food ShortageOne of the most complex problems in the world today concerns the human population. The number of people living off the earth and putting strain on its ecosystem has doubled in just forty years. In 1960 we were 3 billion; today there are 6 billion. We have no idea what maximum number of people the earth can support. Therefore, the first question that comes to people's minds is: will there be enough food for all of us in the future? There is no answer to this. Food shortages have become a serious problem in many countries around the world. There are many different reasons why people are starving all over the world. The lack of economic justice and water scarcity are just two examples among all. Danielle Knight stated that “The real source of world hunger is not scarcity but politics; not inevitability but politics, the real culprits are economies that fail to offer opportunities to all and societies that put economic efficiency before compassion.” The author tries to say that, ultimately, world hunger is mainly caused by us human beings. The world provides more than enough food for every one of us on earth, according to the report "World Hunger: Twelve Myths." The problem is that there are so many people living in third world countries who don't have the money to pay for easily available food. Even though their country has excess food, they continue to suffer from hunger due to poverty. Because people are mistaken in saying that “scarcity is the real cause of this problem,” governments and institutions are starting to solve food shortage problems by increasing food production, while in some countries there is indeed a glut of food. Although the Green Revolution has been a great success globally, hunger still exists in some countries. The author stated: “Big farms, free markets, free trade and more aid from industrialized countries have all been falsely touted as the 'cure' to end hunger.” All this is used to promote exports and food production, but this does not increase the ability of the poor to buy food, he says. What the government should really do is rebalance the economy and allow more people to earn more money to buy more food. Sandra Postel, on the other hand, has a different opinion than Danielle. He proposed that “without increasing water productivity in irrigation, major food-producing regions will not have enough water to support agricultural production”.
