Loose hairs which can easily be removed by plugging may already be dead with little follicle cells with DNA left one of us: Rare focuses on the human activity that threatens biodiversity and habitats such as overfishing and unsustainable agriculture.

Zoos also use SSPs as research tools to better understand wildlife biology and population dynamics, and to raise awareness and funds to support field projects and habitat protection for specific species.
