Ending The Protection Of Grizzly Bears
Grizzly bears, also known as North American brown bears, once roamed much of North America and symbolized the continent’s untamed wilderness. But hunters and trappers nearly wiped them out across most of the Lower 48 states by the late 1800s.
Drones And Wildlife Preservation
We hear more and more about drones these days. There is plenty of controversy about their use in warfare. Drones are also used to snoop on construction projects. Drones are spotted at the beach being used as high-tech toys. And drones are becoming a powerful tool in wildlife protection.
Fungal Diseases And Wildlife
Since the late 1990s, there has been an unprecedented global wave of virulent fungal infections that has been decimating whole groups of animals from salamanders and frogs, to snakes and bats.
Food Waste And Wildlife
We have talked quite a bit about food waste and in particular its impact on world hunger and on the economy. The world wastes more than $750 billion worth of food each year and 1.6 billion tons of food is left in fields, sent to landfills or scattered about the landscape. Another 7 million tons of fishery discards are dumped in the sea.
Beware The Blob
There has been plenty of discussion of El Niño, the periodic weather phenomenon in which prevailing easterly winds in the Pacific Ocean weaken, allowing warm water to move eastward and wreak havoc with the weather in North and South America. The current El Niño is a particularly strong one; some say it may be one of the strongest ever and are calling it the “Godzilla El Niño.”
Road Salt
Snow season is here. The chances are good you’ll find yourself behind a truck spreading salt on the roads in an attempt to deice them. You may even try a little salt on your own front porch. Annually we spread about 20 million tons of road salt in the U.S., and we’ve been doing it since the late 1930s.
Beavers: Nature’s Nitrogen Busters
Beavers are one of nature’s most industrious engineers. Using branches and mud, the intrepid animals create dams that slow moving water. In New York’s Hudson Valley, their constructions are a common sight on streams and in wetlands.
Noise Pollution And Wildlife
Traffic noise is something nobody likes. We shy away from homes too close to highways and major roads. We soundproof our houses. We build noise abatement walls.
Mercury And Selenium Pollution In The Grand Canyon
The Grand Canyon Reach of the Colorado River is breathtaking and remote. For hundreds of miles, the rugged landscape renders the river virtually inaccessible to people. Those intrepid enough to explore the area are treated to red rocks, blue skies, and meandering waters.

We Need More Free-Range Kids
Once-upon-a-time, kids were expected to amuse themselves outdoors. Today, fears of shady neighbors and bodily harm have led to a nation of parents who appear content to keep their kids inside, playing computer games, surfing the web, texting, and watching TV.
The Complicated Case Of Cecil The Lion
The recent killing of Zimbabwe’s Cecil the Lion sparked a world-wide reaction and has focused a great deal of attention on the ethics of trophy hunting. There is no question that trophy hunting is an extremely polarizing issue and there are demands around the world to curtail the practice.
Tech Advances Provide Window Into Wildlife
Since the evolution of our earliest ancestors, people have looked to clues – such as footprints in the mud or rubs on trees – to gain insight into wildlife behavior.
