Famine-the major Cause of Malnutrition:

Famine is the lack of enough food to feed all the people living in an area. It is a social and economic crisis that results in malnutrition and increased mortality Historically, famines have occurred because of drought, crop failure, and because of man-made causes such as war or misguided economic policies. The most terrible famines of the twentieth century include the disaster in Bengal (1942-1945), famines in China (1928 and 1942), and famine in Ukraine (1932-33). The last great famines of this century were the disaster in Cambodia Ethiopian famine (1983-85) and the North Korean famine (the 1990s). Famine may be due to unequal distribution of flood, drought, flooding, or increasing population.

Unequal distribution of food:

The achievements in science have enabled human beings to produce better food in terms of quality and quantity. Today the agricultural practices produce more than enough food that can be supplied to everyone on earth. But due to political and administrative problems, the food is not equally distributed to the different regions of the world. The result is that there is always surplus food in countries like America, the UK, Canada, etc, and at the same time people have nothing to eat in countries like Ethiopia, Somalia, etc.
