One man's lonely quest to save the world's corals draws a following

Tottenville, on Staten Island, will get oyster-friendly breakwaters and a dune system as part of post-Sandy rebuilding efforts. The oysters will help revive the ecosystem and sustain the long-term fishing economy.

Warming water has led to the collapse of coral reef systems in the western Indian Ocean, essential to fisheries, protecting shorelines, and reducing beach erosion and sea-level rise. Marine scientists from Nature Seychelles, as part of an international project to protect and restore the reefs, are promoting varieties of coral that they have found to be resistant to the rise in temperature.

Concerned with colony collapse syndrome in honey bees worldwide, scientists, farmers and tech companies teamed up in Australia to create a micro-sensor that collects data on the bee's environment.

The World Conservation Union estimates that 40 percent of the more than 40,000 species it tracks on its Red List are close to extinction and this problem requires humans to change their behavior to fix it. Rare’s the Pride Campaign uses social marketing to attract attention and communicate the conservation message between local communities and government entities. The Pride Campaign has been replicated around the world for different conservation efforts to protect biodiversity.

A robust population of grizzly bears can be an indicator of healthy land; however, the bears also can destroy grain bins, consume vegetation, and kill livestock. Ranchers work with the Canadian government and local conservation groups to protect their resources with bear-proof grain bins and electric fences.

In California some farms lose up to 10 percent of their crop due to coddling moths. Davis University is measuring the impact bats have on various walnut farms, such as potential savings from reduced insecticide use and crop loss to insects.

When cattle die on ranches in Montana, they can attract grizzly bears that can come dangerously close landowners, ranches, and living livestock. Blackfoot Challenge, a coalition of ranchers and landowners who work with the government, collects and composts dead cattle into odorless woodchips. These woodchips are effective at repurposing carcasses into high-way side revegetation projects.

Often it is faster and easier to harvest molecules for medical purposes from nature than to make them in a laboratory. A scientist is looking for cancer-fighting molecules in coral and sponges in the tropical Pacific.

Many wildlife are killed each year as they are hit by cars when crossing highways. Montana built crossing structures over high risk sections of highways, such as grass covered tunnels, for animals to cross safely and reduce car accidents.

Wolves in western America were once hunted to near-extinction but have now been reintroduced into certain territories with notable success. More wolves often means more attacks on ranchers' livestock, however, so cowboys are working to track wolf packs by computer to reduce conflicts.
