[1] It relies on predation , parasitism , herbivory , or other natural mechanisms, but typically also involves an active human management role.
Biosafety, in medicine and health care settings, specifically refers to proper handling of organs or tissues from biological origin, or genetic therapy products, viruses with respect to the environment, [7] to ensure the safety of health care workers, researchers, lab staff, patients, and the general public.

Mosquito-control operations are targeted to multiple problems: Nuisance mosquitoes bother people around homes or in parks and recreational areas;
Homochirality is an obvious characteristic of life on Earth, yet extraterrestrial samples contain largely racemic compounds. [7] It is not known whether homochirality existed before life, whether the building blocks of life must have this particular chirality, or whether life must be homochiral at all. [8] [9] What do all the unknown proteins do?
A biological hazard, or biohazard, is a biological substance that poses a threat (or is a hazard) to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other living beings. [a]

Biological pest control does not seek to eradicate pests, but to keep them to economically ...
