Biodiversity refers to the variety of life forms on this planet. The variety of genetic information contained in all organisms. The variety of different living species. The variety of habitats, the species that live in the habitat, and ecological processes. Biodiversity is invaluable to the process of evolution since it represents the pool of resources from which evolution can select.
Biological diversity is the key to adaptation to changes.
The greater the biodiversity, the more resilient an ecosystem will be to recover from natural disasters or human intrusions. As the human population increase, new breeds of superyielding crops may be needed to meet the demand for food. The biota of the rainforests is likely to be the source for cures of existing and emerging diseases. These challenges can only be met if there is enough genetic resource available and is reason why preserving biodiversity is so vital. Convention for Biological Diversity Efforts to raise awareness about the importance of Earth's biodiversity culminated in the Convention for Biological Diversity in Rio in June 1992, in which 156 nations signed the legally binding pledge.
