Are sea otters the new global warming warriors? By preying on urchins - which themselves devour kelp forests - sea otters help the plants to flourish. A kelp forest protected by otters absorbs 12 times as much CO2.
Right after the Deepwater Horizon oil spill in the Gulf of Mexico, United States President Obama appointed a commission to come up with a comprehensive strategy for restoring the Gulf's ecosystem.

Floods bring to mind destruction, but the ecosystems of floodplains and estuaries depend on the occasional deluge, so each year the U.S. Army Corps of Engineers times the release of large volumes of water.

In 1963 scientists discovered industrial air pollution was acidifying water that rained down from the sky, killing ecosystems of streams. Fifty years later, there's less acid rain. But rivers aren't neutral, they're alkaline.

Biosphere 2 is a completely enclosed habitat designed to research the interactions within ecosystems and to explore the possibility of colonizing outer space.

Its positive buoyancy prevents the sub from landing on a reef, and its low light and noise emissions ensure the fragile ocean ecosystems remain undisturbed.
If done with no environmental impact study on the unique and delicate ecosystem of a coastal area, this project may result in the destruction of mangrove trees and natural reefs buffers, resulting in extreme beach erosion.
Balls of moss on glaciers, called mice, contain miniature ecosystems. In fact, with inner temperatures warmer than the surrounding ice and a constant water supply, these roving worlds teem with life.

Some biologists are studying how separate species orchestrate different sounds together, and how the resulting soundscape can be used to gauge the health of ecosystems.

A team of Russian scientists is just 100 feet from drilling into a vast Antarctic lake, a primitive and pristine ecosystem that has been untouched for millions of years.
