THE EXTINCT THE ENDANGERED THE THREATENED
2
DEFINITIONS???? EXTINCT ENDANGERED THREATENED VULNERABLE
3
Facts & rates 99% of all species that have ever existed on Earth are now extinct Natural rate of extinction is 1 species/day Man-accelerated rate of extinction is 137species /day (that’s 50,000 sp/year) –current updates say it’s now 20 species an hour. That’s # / yr? _____________ #1 reason organisms are endangered is habitat destruction ! 150 acres of rainforest are destroyed each min (that’s like 1-2 football fields a sec!!!) For every keystone species that disappears, soon follow) 175,000!

Cheat sheet of facts on species (status & reasons)
dinosaurs Extinct Meteor theory Birds of prey Endangered to threatened DDT & biological magnification Piping plover endangered Wetland destruction spotted owl threatened old growth forest destruction Panda bear Endangered/vulnerable Habitat fragmentation + breeding + food issues Swamp pink + pitcher plant Endangered wetland destruction Florida manatee Red tide +boats, Ms. Waldron’s red colubus Extinct?(not seen since early 2000 Habitat fragmentation & overhunted
32
species status reason Metalmark butterfly threatened Global climate change Rhinos, grizzly, & tiger endangered Poachng and aphrodisiacs quetzal Global climate change + nonnative species Passenger pigeon extinct overhunted Red wolf Hunted & poisoned(govt extermination) California condor Hunted & poisoned and related complications frogs Parasite and pollution
33
ANY LAWS ON THIS STUFF? ENDANGERED SPECIES ACT
ENDANGERED SPECIES PRESERVATION ACT CITES (CONVENTION ON INTERNATIONAL TRADE OF ENDANGERED SPECIES)
34
DO YOU REMEMBER WHAT YOU SAW IN THE EFFORTS TO SAVE THE RED WOLF?
35
This is a coyote!
36
What ethics exist in saving these species?
(as a team list pros and cons….use specifics as best possible. esp for wolf populations) Which values are anthropocentric? Which biocentric?
37
In a "closed" system..... like Earth.....
38
