Biodiversity describes the variety of life in an area, including the number of different species, the genetic wealth within each species, the interrelationships between them, and the natural areas where they occur.
Biodiversity is not evenly distributed across the globe due to variations in climatic conditions and topography. For instance, South Africa contains almost 10% of the world's total known bird, fish and plant species, and over 6% of the world's mammal and reptile species.
Unfortunately, this natural wealth is threatened by the combined actions of our society. There is pressure from growing human populations and their demands on the environment. Major threats are from unsustainable socio-economic development, agricultural practices, rapid urbanization, illegal trade in biodiversity materials, and most recently climate change phenomenon
