Document Summary

Conservation biology: integrates ecology, physiology, molecular biology, genetics, and evolutionary biology to conserve biological diversity at all levels. Three levels of biodiversity: genetic diversity, species diversity, and ecosystem diversity. Genetic diversity: individual genetic variation within a population and also between populations that is associated with adaptations to local conditions. Ecosystem diversity: local extinction of one species can have a negative impact on other species in the ecosystem. Many threatened species could potentially provide medicines, food, and fibers for human use like aspirin and antibiotics. Ecosystem services: all the processes through which natural ecosystems help sustain human life. Habitat loss: agriculture, urban development, forestry, mining, pollution by man, this gets rid of tons of species. Introduced species: also known as exotic species, moved by humans intentionally or accidentally from the species" native locations to new geographic regions: these can kill the native species and is not good.
