the relationship between the human species and its physical environment
human ecology
the results of an action that were not the expected or intended results
unintended consequences
changes in world climate patterns that are directly caused by human activites
anthropogenic climate change
negative effects of deforestation
loss of wildlife, increased erosion, soil desication
events in the Earth’s past when a large proportion of the world’s biodiversity vanished in a geologically very short time period
mass extinction
the hypothesis that human overhunting caused many large Late Pleistocene mammals to go extinct soon after humans moved into the same regions
overkill hypothesis
agricultural fields with only one crop
monocrop fields
most diversity loss today due to:
loss of habitat, invasive species
current population growth rate
about 0.19% per annum
Malthusian population controls
war, famine, epidemic
the total fertility rate at which population remains constant
replacement rate
