Current mega extinction |
is caused by a species compared to some major external force |
|
|
What's happening to Tropical Rain Forest |
-tough environment to live in for humans - continues to decline 1) Ecosystem destruction 2) ecosystem degradation -also includes climate 3) direct hunting and harvest 4) introduced species |
|
|
ecosystem destruction |
-destroy it and let it come back -houses, roads, lawns, mining, nuclear bombs |
|
|
ecosystem degradation |
-disturbances; road salt, light messes with animals biorhythm (light should only be in the day), pesticides, fragmentation (fencing), ozone depletion |

|
speed of climate change |
is currently very fast life wont have time to adjust and adapt & migrate for example, everglades climate park will be flooded in a century because of climate change |
|
|
direct hunting and harvest |
- demand for a resource -rosewood, ebony, mahogony, ivory - people collect rare things -ex: had to get rid of buffalo for trains -buffalo--from pop. 60 mill-->85 -passenger pigeon-- from 5 nil--> extinct -species need a certain amount of pop. to survive |

-invasive species change landscape, they have no competition, so they explode 1) Laws to protect endangered species and threatened -have to document and prove your case, if its not abundant, can be considered endangered orphin--species nobody cares about ex: bee 2) ecosystem protection-- more broader view 3) CITES (treaty): protect species species 4) Educate people on value of biodiversity -human centered argument --free services, meds, food/flaws. aesthetics, biophilia (hardwired to interact with natures spiritual |
