Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry, which is operated by multinational corporations that use intensive farming and industrial agriculture to maximize system output.
Food safety and food security are monitored by agencies like the International Association for Food Protection, World Resources Institute, World Food Programme, Food and Agriculture Organization, and International Food Information Council. They address issues such as sustainability, biological diversity, climate change, nutritional economics, population growth, water supply, and access to food.
The right to food is a human right derived from the International Covenant on Economic, Social and Cultural Rights (ICESCR), recognizing the "right to an adequate standard of living, including adequate food", as well as the "fundamental right to be free from hunger".
The Wal-Mart camel is the fossil of a prehistoric camel (Camelops sp.) found at a Wal-Mart construction site in Mesa, Arizona in 2007. Workers digging a hole for an ornamental citrus tree found the bones of two (juvenile and infant) animals that may have lived as long as 10,000 years ago. Arizona State University Geology Museum curator Brad Archer calls it an important and rare find for the area.Wal-Mart officials and Greenfield Citrus Nursery owner John Babiarz whose crew discovered the remains agreed that the bones will go directly to the Geology Museum at Arizona State University where further research and restoration of the fossils could be done. Camels lived in what is now Arizona until about 8,000 years ago.More camel bones were found in Gilbert, Arizona in May 2008.
happy time
