Wolves Revive Yellowstone
Wolves were hunted out of Yellowstone and without them the entire ecosystem suffered. When they were reintroduced after being absent for nearly 70 years, a remarkable "trophic cascade" occurred.
On the island of Madagascar, we can see one of the main factors driving the loss of tropical forests: the growing demand for land. We need to understand biodiversity as a world resource, otherwise ⅔ of species-including the lemurs-may be gone by century's end.
Keepers of the Prairie
Prairie Dogs are essential for the preservation of the vast American Prairie. They are prey for others, their towns provide habitat for up to 150 other species, and they maintain overall grass health.
Elephants Without Borders
Elephants Without Borders scientist Mike Chase puts a radio collar on an elephant, and explains how tracking helps define areas that need to be protected and connected for elephant survival.
Whales Help Climate Change
When whales were at their historic numbers, they may have been responsible for removing tens of millions of tons of carbon from the atmosphere every year. If they are allowed to recover, it could undo some of the damage we as humans have done.
Create a Pollinator Refuge
A native plant garden helps recover endangered pollinators threatened by human development. Not only are these species important for overall ecosystem health, but they are also responsible for pollinating 1/3 of all the food we eat.
