BIODIVERSITY & HUMAN IMPACT PowerPoint, Notes & Practice Q’s

Biodiversity: all the different organisms in an area HIGH in ocean & rainforest LOW in desert & tundra Stable Ecosystem HABITAT - organism’s environment NICHE - organism’s way of life (role) ADAPT - respond to change RESILIENCE - recover from disasters BALANCE - nutrients & resources

HOW do humans mess up the balance?

H I P O abitat Destruction nvasive Species ollution opulation Grown verhunting

HABITAT DESTRUCTION

Habitat Destruction Activity Examples Reason Effect DEFORESTATION: Clearing trees DRAINING WETLANDS: Filling in ponds/lakes Disrupt food chain Migrate or become endangered/extinct More CO2, Less O2 Space for building Room for crops Food, lumber, medicine, paper

INVASIVE SPECIES

Invasive Species Activity Examples Reason Effect NON-NATIVE: Not originally from area Kudzu, Zebra Mussels, Burmese Pythons NO NATURAL PREDATORS Reproduce quickly Compete with natives for resources Control environmental problems Accident or for exploitation

POLLUTION

Killing animals & plants Activity Examples Reason Effect Pollution Global Warming Acid Rain Killing animals & plants AIR: burning fuels WATER: sewage & runoff LAND: landfills CONVENIENCE More humans = Use more resources

Population Growth 3x amount of people 1950-2000 Activity Examples Reason Effect Population Growth 3x amount of people 1950-2000 URBANIZATION (developing cities) Better medicine & treatments More opportunity in cities Less resources for ecosystems Rise in CO2 levels (global warming)

Overhunting Food, clothing, medicines Fun/sport Biodiversity loss Activity Examples Reason Effect Overhunting Food, clothing, medicines Fun/sport Biodiversity loss Greater risk of endangered / extinct Hunting & Poaching Overfishing
