Poaching and Biodiversity

-Poaching poses an urgent threat to African biodiversity because it leaves many animal populations devastated and unable to survive in the wild. (Unsustainable)
-When a certain amount of individual organisms are removed, a population can no longer sustain itself in the wild.
-The extinction of one species may also affect other local species as species dominance shifts or the survival mechanisms of other species are compromised.

Four benefits of biodiversity
1.       Ethics and respect of life
2.       Economic development: Well managed biological resources can provide food/goods for an indefinite period of time
3.       Maintains natural ecological cycles such as seed dispersal and nutrient cycling
4.       Wildlife, sensitive to chemicals, function as pollutant indicators
