Dear EarthTalk: What is “biomass” and why is it controversial as a potential source of energy?-- Edward White, New Bedford, MA

Biomass is plant matter that is burned as a source of energy. Fallen or cut wood that is burned for heat is one primary form of biomass, but another includes plant or animal matter that is converted into biofuels.

Dear EarthTalk: What are some tips for keeping my dogs and cats healthy?-- Kim Newfield, via e-mail

Believe it or not, our pets may be exposed to more harsh chemicals through the course of their day than we are. Researchers at the non-profit Environmental Working Group (EWG) found that pet dogs and cats were contaminated with 48 of 70 industrial chemicals tested, including 43 chemicals at levels higher than those typically found in people.

Dear EarthTalk: Why is it that airplane exhaust is so much worse for the environment than engine emissions on the ground?-- Winona Sharpe, New York, NY

For nearly a decade, New Hampshire has been seeking hundreds of millions of dollars from oil companies over the chemical additive MTBE, which the state says caused contamination in the state’s groundwater. The legal proceedings originally involved 26 oil companies; as trial began this week, there were just two left, ExxonMobil and Citgo, and now there may be just one.

Dear EarthTalk: I’ve heard of Eco-Tourism, but what on Earth is “Geo-Tourism? -- Sally Kardaman, Sumter, SC

“Geotourism” describes tourism that sustains or enhances the geographical character of a given place, including its environment, culture, aesthetics, heritage and the well-being of local residents. The idea is that tourism can be a positive force that benefits both travelers and local environments and economies.

A proposed wind farm in the Newfound Lake area has once again raised familiar themes in New Hampshire: A desire for the Granite state to use more clean energy, versus local concerns over property values, as well as impacts on the environment and tourism. We’ll re-examine these arguments in light of this new proposal.

In a new book, author David Owen exposes the complexities of what it means to truly be “green”.  He says supposedly earth-friendly ideas like hybrid cars or solar panels create efficiencies which allow us to consume more!   Efficiency, Owen says, once considered the Holy Grail of our environmental problems, turns out to be part of the problem!

Dear EarthTalk: A friend of mine told me that our government kills thousands of wild animals like bears and wolves every year in the name of protecting livestock. How can the government, which is supposed to protect dwindling numbers of animals, instead be killing them?       -- Amy Pratt, Troy, NY

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.

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.
