Question 3

Give several examples of in situ and ex situ conservation.What are advantages and disadvantages of each approach to conservation?

Accepted Answer

Concepts to Consider: In situ conservation efforts include national parks, forests, and refuges--disadvantages revolve around their multiple uses, including allowing hunting, livestock grazing, development for fossil fuels, and military uses, but advantages include large size, and the possibility of conserving biodiversity in the wild; ex situ conservation efforts include zoos, aquaria, botanical gardens, as well as artificial insemination, host mothering, and captive breeding--drawbacks are related to their relatively limited focus on a few species, but advantages allow countries with more financial resources to captive breed endangered species for reintroduction.
