Dear EarthTalk: I can’t seem to find any natural bug repellents that really work so I end up using the harsh, chemical varieties. Are there any really effective bug repellants that aren’t chemically based, or other strategies we can use to keep bugs at bay? -- Melissa Armantine, New Paltz, NY
Dear EarthTalk: American farmers are an aging population. Is anyone doing anything to make sure younger people are taking up this profession in large enough numbers to keep at least some of our food production domestic?-- Beverly Smith, Milwaukee, WI
Giant and colossal squids can be more than 40 feet long, if you measure all the way out to the tip of their two long feeding tentacles. But it's their eyes that are truly huge — the size of basketballs.
Now, scientists say these squids may have the biggest eyes in the animal kingdom because they need to detect a major predator, the sperm whale, as it moves toward them through the underwater darkness.
This year, the New Hampshire Department of Environmental Services turns 25 years old. Its Commissioner, Tom Burack says that over that time a lot of progress has been made in terms of clean water, air and land, but there’s still a long way to go. “This legacy,” Burack says “requires vigilance and maintenance”. Those are tough goals, and with recent budget cuts to his department it makes it even that much more tough.
The man who warned us that aerosol spray-cans could destroy the earth's protective ozone layer has died.
F. Sherwood Rowland, better known as Sherry Rowland, was a Nobel-prize winning chemist at the University of California, Irvine. And he didn't just keep to the laboratory: He successfully advocated for a ban on ozone-destroying chemicals called CFCs.
For tens of thousands of years, humans relied on animals to sustain life: their skins kept us warm, their oils provided fuel. But the 7-billion of us stomping the earth today? Our relationship with the creatures around us is vastly different. Around the globe, species big and small remain under intense threat of extinction. A new book, ‘Wildlife Heroes’ tells the story of forty leading conservationists who are fighting behind the scenes to save these animals.
In New Hampshire we value rural character—a value that's reflected in a strong history of land conservation. Central to that history is conservation of privately owned land by means of what's called a "conservation easement deed" that limits future development. It's typically a family decision. A family chooses to conserve their land so that future generations will know the land as they do. The property stays on a town's tax rolls and its natural resources are protected in perpetuity. Land conservation benefits the public, and in most cases landowners are entitled to an income tax dedu
If you head to Yosemite National Park this time of year and stop by Horsetail Fall at just the right time, you might see something spectacular: As the sun sinks low in the sky, the waterfall glows with streaks of gold and yellow — and it looks just like molten lava.
Photographers like Michael Frye flock to the park every February to try to capture the phenomenon. Frye, author of The Photographer's Guide to Yosemite, describes the sight to NPR's Audie Cornish.
Mother and calf common dolphins are transported to the beach by a team from the International Fund for Animal Welfare and the New England Aquarium before being released back into Cape Cod Bay on Jan. 14. So far, area rescuers have counted 147 dolphin strandings this winter alone.
Dolphins have been stranding themselves along the shores of Cape Cod, Mass., since the Pilgrims' times, and this winter is no different. What is different is how long the latest round of strandings has lasted — almost a month. So far, rescuers have counted 147 strandings and 38 successful rescues and releases.
Dear EarthTalk: I was horrified to read recently that our oceans are actually becoming acidic, that the continued burning of fossil fuels is changing the chemistry of our seas. What’s going on? -- Kim Richardson, San Diego, CA
Dear EarthTalk: Is it true that cable and other pay TV boxes that sit atop television sets consume massive amounts of energy, in part because they are always on, even when the TV is off? -- Sam Winston, Metarie, LA
