It is very important to define biodiversity prior to define agro-biodiversity, therefore,  Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems.

Agro-biodiversity is an important part of biodiversity, and the source that provides food for humanity. It includes all the creatures that are related directly or indirectly to the Agricultural process of producing our food from fruit trees and field crops and farm animals as well as pastures and forests in addition to fishes, birds, insects (including pollinators) and fungi and other materials that are used by humans. Moreover, pests that cause damage to agricultural products can also be included. In other words, Agrobiodiversity is the result of a combination of natural selection processes and the careful selection and inventive developments made by humans since the beginning of farming and domestication of plants and animals over millennia.

Protecting the wildlife in the natural habitats might be of benefit to the future humanity in conserving a resource that has not yet been used for economical reasons, but might be in the near future. This will be the case when our knowledge on the many secrets of Mother Nature are being revealed with the advance of science of using and benefiting directly or indirectly from such components.
