*Alien/Invasive: Species
The introduction of species into a habitat that wasn’t originally found in that area
-
-
Ex. Asian beetles, zebra mussels, water milfoil, buckthorn
Habitat loss:Universally accepted as the primary threat to biodiversity.
Habitat Fragmentation: the division of a large habitat area into smaller areas. Affects the amount and type of species that live in the smaller areas.
-Roads, building, urban sprawl, deforestation
-Species to suffer the most are migratory animals & large predators
Air Pollution: Consists of chemical substances and particles released into the atmosphere, mainly by human activities
Major cause: burning of fossil fuels
Fertilizers, farming (dust), fumes from chemicals
Overpopulation: Human population continues to increase therefore, habitat is lost due to human expansion for housing/buildings, land converted for agricultural use, hunting, fishing, etc…..
-
Climate Change:CO2 from burning fossil fuels increases the greenhouse effect
Gases in atmosphere radiate heat back to Earth’s surface (like a blanket)
Preventing Biodiversity Loss:Is the use of natural resources in a way that meets the needs of the present and preserves the resources for the future
Farming practices
Forest use
Umbrella Species: A species that, if protected, also provides protection to other organisms by default.
Ex: If you protect the prairie for the Sage Grouse, ALL other organisms that live there are now also protected (350 other species).
