The genetic diversity of plants and animals makes them more adaptable to diverse kinds of environmental changes. It is needed to safeguard vital traits that could help them fight unexpected pests and environmental stresses. Seed banks, protected areas, and enabling beneficial traits in crops are all ways in which genetic diversity can be enhanced and preserved. Monocultures, however, are detrimental to genetic diversity. The restricted breeding and planting of a single species can throw the ecosystem out of balance.
