Economy on our planet is a key element to the survival of billions of people. The word itself comes from the Greek “oikonomia,” meaning management of a household. In that context, economy would include not only financial exchanges, but also a range of social and environmental transactions people undertake to make a living. These external transactions may include industrial output and energy consumption, as well as the unpaid work of women and children hauling water or fuel-wood, the burning of rainforest to clear land on which to grow food

Clean drinking water and food are things some people take for granted, yet others pray and plead for. An estimated 2 billion citizens of the world lack access to adequate nutrition, and nearly 800 million are chronically hungry. Our supply of fresh water is also severely limited: 31 countries are currently suffering from scarcity or stress and for more than 1 billion people clean drinking water is simply unavailable. Drastic shortages of food and water heighten the gap between rich and poor and often lead to conflicts on all sides. Water wars are almost inevitable, as more people compete for that scarce resource. The push for increased agricultural production to meet growing needs leads to environmental degradation from habitat destruction, chemical pollution from fertilizers, and over-fishing. River systems and aquifers have been seriously depleted by water withdrawals. The introduction of genetically modified organisms in an effort to increase food production has potentially negative environmental and health implications. Not having sufficient amount of food and hygienic drinking water can and will affect most of the people in the global community.<
