Dear EarthTalk: What is currently being done in the U.S. to ensure the wise use and safety of our nation’s groundwater?                                          -- Kevin Orr, Baton Rouge, LA

New Hampshire is the second most forested state in the country, but according to our guest today, UNH Professor and Ecologist, Scott Olinger, our forests face serious challenges from climate change to invasive species.  Today on the Exchange, we're looking at what's happening to our trees, what cane be done to protect them and the environmental significance of our forests.

Despite arguments over effectiveness and cost, New Jersey has long practiced what is called “artificial beach nourishment”—importing and pumping tons of sand to build up its shore.  Much of that sand was swept away by super storm Sandy’s massive surge and the one that followed from the recent nor’easter.

A 2004 poll estimated that thirteen percent of American households keep goldfish. Nearly 500 million are sold each year just to feed other pets. How goldfish became America’s go-to pet is a matter of some debate.

Dear EarthTalk: I have heard that fracking is becoming a major environmental issue in the U.S. Which parts of the country are already hosting fracking operations? Are there efforts underway to stop the practice in specific states or across the country?

Generations ago, when people lived closer to the natural world, more outdoors than in, mild October days were called "bluebird weather. "The eastern bluebirds' gentle, quizzical notes were familiar and their distinctive habits recognized. A bluebird family remains together this time of year when most other bird species disperse. They favor field or open habitat, and typically perch on branches at field edge when they feed. Family members take turns dropping down to the ground then return to perch, one after another, most likely in pursuit of grasshopper or cricket.

The Bicknell’s thrush is a migratory songbird that winters in the Caribbean but comes to northern New England to breed.

It's long been hard to find in the region – and conservationists say that’s becoming a big problem. In fact, the US Fish and Wildlife Service announced last week it’s considering the Bicknell’s thrush for endangered species status.

We talk with Pulitzer Prize winning author Edward Humes about his new book, Garbology: Our Dirty Love Affair with Trash. Americans are at the top of the heap for producing waste: over 100 tons per person in a lifetime.

Humes explores why we make so much garbage, the environmental and economic impact of trash…and why he believes this is a problem ordinary people can fix.

Dear EarthTalk: Do environmentalists think the Endangered Species Act has been a success or failure with regard to protecting biodiversity in the U.S.?-- Ron McKnight, Trenton, NJ

While that very question has been a subject of debate already for decades, most environmental advocates are thankful such legislation is in place and proud of their government for upholding such high standards when it comes to preserving rare species of plants and animals.

With a link between extreme weather and rising greenhouse gases, two thoughts are emerging. Many environmentalists say we should work toward mitigating greenhouse gases but others suggest the problems are irreversible and so we have to adapt to inevitable change. But for some this idea is uncomfortable. They worry that adaptation means giving up. Today we look at these two different thoughts around climate change and see where we go from here.

The Future of Great Bay

Jul 23, 2012
Conservation Law Foundation

Often called New Hampshire’s “hidden coast, the Great Bay is considered an estuary of national significance. Yet, its future seems in question both because pollution has taken a toll on its ecosystem and because nearby communities, activists, and officials can’t agree on how best to eradicate it, even as all realize something must be done. We'll look at the Great Bay debate and see if some sort of compromise can be made?

Dear EarthTalk: I was appalled by the pollution haze I saw on a recent visit to Acadia National Park in Maine, and was told by a ranger that it was from smokestacks and tailpipes hundreds of miles away. Is anything being done to clear the air in Acadia and other natural areas where people go to breathe fresh air and enjoy distant unobstructed views?-- Betty Estason, via e-mail
