Wildlife and Habitat
Salt-water fish save water
An estimated 80% of the water used in the U.S. supports crop and livestock production. Resource managers are increasingly concerned about the excessive amount of water required to satisfy our nation’s appetite for beef. Using conservative estimates, it takes 441 gallons of water to produce one pound of conventionally raised beef. [Read more…] about Salt-water fish save water
Evolutionary traps
It’s no secret that humans affect wildlife in a myriad of ways. But scientists are discovering that even seemingly benign human activities can have enormous consequences when they create evolutionary traps. [Read more…] about Evolutionary traps
High tower decisions
Each year, when migratory North American birds attempt their flight to Central and South America, more than seven million die in collisions with communications towers. Only house cats result in more human-induced bird deaths. [Read more…] about High tower decisions
Golfers can breathe easy
A lot of Americans take to the golf course on Saturday afternoons. There must be something about beating on a little white ball and then chasing it across the countryside that is soothing after a week at work. Across the U.S., prodigious amounts of fertilizer, irrigation water, and pesticides are used to keep golf courses green. Today, let’s focus on the pesticides. [Read more…] about Golfers can breathe easy
Consider going DEET-free
[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2014/01/EW-04-02-14-DEET.mp3|titles=EW 04-02-14 DEET]
DEET, also known as N, N-diethyl-meta-toluamide, was developed during World War II to protect our troops during military operations in the tropical Pacific from mosquitoes and the diseases they carry. It undoubtedly saved thousands of lives. At war’s end, it was commercialized for public use. Countless families have slathered on DEET to ward off bugs on weekend picnics, camping trips, and nature walks. [Read more…] about Consider going DEET-free
Dirty drinking water
A new government study is raising red flags about the safety of our drinking water. EPA and U.S. Geological Survey scientists analyzed treated water samples from 25 U.S. utilities. They found that more than 1/3 contained chemicals not regulated by the federal Safe Drinking Water Act. [Read more…] about Dirty drinking water
The U.S. is emitting less carbon
In 2012, carbon dioxide emissions from energy use in the US reached the lowest level since 1994 and were 12% lower than their peak in 2007. This is certainly good news, but just how good? [Read more…] about The U.S. is emitting less carbon
What’s all the talk about mute swans?
In the late 1800s, mute swans were brought from Europe to the eastern U.S. to enhance the beauty of ponds on private estates. Unlike the dark-billed native swans that migrate through our region in the spring and fall, mute swans are easily distinguished by their pinkish-orange bills. They also spend the entire year here. [Read more…] about What’s all the talk about mute swans?
The costs of a warmer Arctic
As the Arctic warms in response to rising concentrations of carbon dioxide and other greenhouse gases in Earth’s atmosphere, some eagerly anticipate the opening of the Northwest Passage for ship navigation. Others applaud the potential to ramp up petroleum exploration and fishery efforts in the Arctic Ocean. But, there are real costs to Arctic warming. [Read more…] about The costs of a warmer Arctic
Plastic bag ban

California is poised to become the first state to enact an official ban on plastic shopping bags, with a measure currently before the state legislature. [Read more…] about Plastic bag ban
Crude oil: It’s not fish food
When British Petroleum’s Deep Water Horizon oil well blew out in April 2010, many of us saw pictures of crude oil pouring into the sea. Much of that oil never made it to the ocean’s surface, where it might have been skimmed or burned off. Instead, it was dispersed using chemicals that were poorly tested for their effect on marine life. It seems we must live and learn. [Read more…] about Crude oil: It’s not fish food
Water supply and beer
Water has historically been undervalued – at least in those regions with a plentiful supply. It’s seen as natural, abundant and limitless. But climate change and human consumption have put a strain on this natural resource. [Read more…] about Water supply and beer
Treating roads with cheese
[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2014/03/EW-03-14-14-Treating-Roads-with-Cheese.mp3|titles=EW 03-14-14 Treating Roads with Cheese]
Local governments across the country are always experimenting with cheaper and more environmentally responsible ways of keeping roads passable during icy and snowy conditions. Rock salt is the long-standing way to get the job done, but it is harmful to cars, washes away easily, pollutes waterways, and kills vegetation. [Read more…] about Treating roads with cheese
Trains and oil spills
[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2014/03/EW-03-11-14-Trains-and-Oil-Spills.mp3|titles=EW 03-11-14 Trains and Oil Spills]
During the past five years, U.S. domestic oil production has risen 50 percent. This surge has outpaced the pipeline infrastructure needed to move oil to consumers. [Read more…] about Trains and oil spills
Cold weather – Warm climate
[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2014/03/EW-03-06-14-Cold-Weather-Warm-Climate.mp3|titles=EW 03-06-14 Cold Weather Warm Climate]
For pretty much everyone living east of the Mississippi River, this winter has been cold, snowy, and icy. We’ve all heard about the Polar Vortex and many of us have spent untold hours with our shovels and snow blowers. All in all, it seems like global warming has gone on vacation. [Read more…] about Cold weather – Warm climate
A mosquito fever expands its range
A mosquito-borne virus that causes fever, headaches, and severe joint pain has spread to the Caribbean. Experts fear it’s only a matter of time before it makes its way to the U.S. Chikungunya gets its name from an East African word meaning ‘that which bends,’ due to the posture of its sufferers.

Growing insects on the farm

The precipitous decline in pollinating insects – particularly bees – has become an issue of great concern around the world. Insects pollinate 75% of the crops that we rely on for food worldwide, and bee populations have declined by as much as 96% over the past century. [Read more…] about Growing insects on the farm
Salty streams and rivers
By the looks of it, we’re in for quite a winter this year. Here in the Northeast, we’ve seen several heavy snowfalls, freezing temperatures, and icy roads. [Read more…] about Salty streams and rivers
