Significance of Biodiversity
indicates healthy functioning of the earth's many ecosystems
3 Aspects of Biodiversity

Spesies Diversity
the variety of living organism estimated 5 and 50 million or more
Genetic Diversity
sum total of all the genetic information carried by individual organisms.
eye colour, colour of skins, susceptibility to cancer
6 Categories of Genetic Resources

Wild Relatives
Primitive Cultivars
Modern Cultivars
Advanced Breeding Lines
Genes from other species
