The core threats to biodiversity are human population growth and unsustainable resource use. Current significant threats to biodiversity include habitat loss, overharvesting/overexploitation, invasive species, and climate change. Conservation biology works to counteract the loss of biodiversity due to these threats. These methods include legislative framework such as the ESA and MBA, setting aside preserves, habitat restoration, and captive breeding programs.
By the end of this section, you will be able to do the following:
Define biodiversity in terms of species diversity and abundance
Describe biodiversity as the equilibrium of naturally fluctuating rates of extinction and speciation
Identify historical causes of high extinction rates in Earth’s history
