Human Impact The human population is increasing at a rapid rate This can cause other species to go extinct Other species are disappearing 1000X faster than they ever have Humans deplete resources
3
Habitat Loss 1970’s-1980’s Amazonian rain forests were cleared to create farmland. Land became worthless because rain forest soil has little use Clearing land erased habitats Coral Reefs-Disease and changes in water temperature can kill coral
4
Habitat Degradation Habitat degradation is damage to a habitat by pollution Acid Precipitation Ozone Depletion Water Pollution Land Pollution As human population increases we must destroy ecosystems to build homes, buildings, factories, etc. Damages biodiversity
5
Hunting Unregulated hunting can lead to extinction American Buffalo were nearly hunted to extinction in the 1800’s Due to newly passed laws they have not been hunted and have now grown to almost 200,000 Poaching-Illegal hunting
6
Habitat Fragmentation Separation of wilderness areas from other wilderness areas Effects: Increased extinction Disruption of ecological processes Biodiversity is decreased
8
Endangered Species in NC 1 out of every 5 species in North Carolina is either threatened or endangered Habitat Loss- People begin to build on undeveloped areas which kills habitats
9
Endangered Species in NC Reptiles-Loggerhead Sea Turtle Mammals-North Carolina Flying Squirrel Insects-Spruce-Fir Moss Spider Birds-Red-Cockaded Woodpecker
