Biodiversity is a word that describes the variety of living things.
Genetic diversity means that an Ethiopian looks different from a Scandinavian or a Japanese person and that inherited diseases run in some families, but not in others. Genetic diversity is the reason why Siamese cats have different body shape and hair colouring from the black and white moggy next door. There is evolutionary diversity, which has given rise to all the different species of animals and plants on this Earth and is genetic diversity on a wider scale. This is also known as species diversity. Only the human species, through cultural and racial diversity and technology, seems to have adapted itself to survive in almost every environment on Earth.
