Learn about animals, both domestic and wild, who have become heroes when they came to the rescue of humans.

With their long tusks, narwhals are unique whales that live in the Arctic Ocean. But as climate change causes global temperatures to rise, less and less sea ice is covering the Arctic Ocean each year. Narwhals are left vulnerable without the ice, which historically provided them with safe areas to roam out of reach of their natural predators, killer whales. And humans are taking advantage of the clearer water, searching and drilling for oil and hauling cargo.

At one time, red wolves roamed the US from southern New York to as far south as Florida and as far west as Texas. But as European settlers moved in, these wolves began losing their home range and were hunted as a threat. Red wolves became so rare by 1973 that they were given protection under the US Endangered Species Act. Then scientists came up with a daring plan: round up all remaining red wolves, launch a captive breeding program, and once the captive population was large enough, release red wolves to roam free in protected areas.

Honey bees are among the world’s most important insects. They help pollinate many of the crops we depend on for food. Without them, the global food supply would be in great danger. In 1998, beekeepers in Europe made a shocking discovery—almost all of the honey bees had disappeared from their hives. Several years later, beekeepers in the United States found that many of their honey bees had vanished too. Scientists called this disappearance colony collapse disorder (CCD), and at first, no one knew why it was happening.
