Conservation of biodiversity
What is genetic diversity?
biological variation within a species
What is species diversity?
number + relative abundance of different species in an ecosystem
What is ecosystem diversity?
variety of ecosystems and habitats within a geographical location
What does evidence from fossils suggest?
greater biodiversity of life on earth than at any time in the past
Extinction of species + ecosystems
Give an example of the loss of terrestrial megafauna
North Island giant moas → exterminated by humans overhunting for food
Give an example of the loss of marine species
Caribbean monk seals → exterminated by humans overhunting for meat and
oil, + overfishing of their natural prey
Give 2 examples of ecosystem extinction
mixed dipterocarp in SE Asia → overexploitation for timber extraction,
cleared for palm oil planting
peatbogs in England → endangered bc drained, burned, built on, farmed,
dug up for fuel and garden compost
Biodiversity crisis
What does the Intergovernmental Science-Poly platform on biodiversity and
Ecosystem Service do?
