Our Earth is a 4.6 billion year old Planet. It is a storehouse of 17,19,183 known species of plants and animal and bears the pressure of 7.5 billion human beings. Since the antiquity of man, plants and animals have played a dominant role in meeting manÔs needs and greed.
Diversity of plant and animal life formulate the support structure. Civilizations of the world have used this support structure for their growth, progress, development and advancement.
Resources available for the human consumption are highly limited whereas the population of the world is increasing at an alarming rate. Humans thrive on less than 17 percent of the earthÔs surface and only 4 percent grow crops. As a result of this, there is a mismatch between food available and consumers.
According to World Food Summit (1996), food security exists, when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preference for an active and healthy life.
