Nobody is sure whether the simultaneous drop in wildflower diversity is the cause or the effect of the bee decline. But scientists think the overall phenomenon may be linked mainly to loss of habitat for both plants and bees as countryside is plowed over for development--yet another price nature is paying for human civilization...
...trash left in rooms, but he noted that the amount of trash students have left behind “has shrunk significantly in the past five years.” He attributed the decreased amount of trash to greater awareness by students of the option to donate items to Habitat for Humanity and the efforts made by Yard and House personnel to remind students to dispose of or donate their unwanted items...

...Florida to no more than 300,000. Now there are 1 million to 2 million. At the same time, the state's human population has exploded.

Everglades National Park is just one-seventh the size of the historic Everglades swampland, forcing the animals to share territory that humans consider their...
Other birds seem to be in trouble because of habitat loss. The decline of the rusty blackbird, for example-one of the most rapidly dwindling species in North America, says Butcher-may also be due to global warming, but the immediate cause seems to be a drying up of the Canadian wetlands where it breeds. The same may apply to the Canada warbler. The cerulean warbler, also in decline, is losing habitat not because of global warming but because of another human activity: the destruction of Appalachian mountaintop forests by coal-mining operations...
