Fact #1Biodiversity can be measured on three levels: species diversity, ecosystem diversity, and genetic diversity.
Species diversity means the sheer variety of living things, from microscopic bacteria and fungi to towering redwoods and enormous blue whales. Ecosystem diversity is tropical rainforests, deserts, swamps, tundra, and everything in between. Genetic diversity is the variety of genes within a single species, which give rise to the variations that cause species to evolve and adapt over time
