The decline in the diversity of crops and animals is occurring in tandem with the need to sharply increase world food production and as a changing environment makes it more important than ever to have a large genetic pool to enable organisms to withstand and adapt to new conditions. Therefore, it needs to strengthen the protection and utilization of these plant and animal species diversity.
