Also called biological diversity, biodiversity is the great number of different species of plants and animals.

Biological pollution is the movement of living organisms, either accidentally or intentionally, from the places where they evolved to new environments where a lack of natural enemies permits their population to explode.

Biopiracy is the act of exploiting indigenous knowledge of nature for commercial gain with no compensation to the indigenous people themselves.

Bioprospecting is the search for plants or animals from which commercially valuable products can be obtained.

Biotechnology uses biological technology to move or change the genes or DNA inside a plant or animal. It can be used to make a plant more resilient to certain weather conditions, like droughts or floods, or to make high-yielding crop varieties. Biotechnology is also called genetic engineering.
