In big cities and rural towns, many communities are beginning to use a concept called “Complete Streets” to make neighborhood and commercial streets friendlier for people. The policies behind these changes are new, but the problems and complaints they are addressing are often as old as the roads they aim to fix.

“Complete streets” look different in different places, but the idea is simple: Make transportation systems about people, so there is equal access for all forms of travel.

Summer in southeast Alaska is salmon season. As the days grow long, the iconic pink fish begin to run up rivers and streams, and the fishing economy jumps to life. But this summer, fishermen are worried that new mining development could put their livelihoods at risk.

Illegal trafficking of animals for Asian medicine is a rampant problem. Despite international protections, poachers slaughter millions of elephants, tigers and rhinos a year and sell their parts as cures for ailments ranging from headaches to cancer.

Now international groups are seeking to protect a small mammal that's trafficked more than those three combined and is on the brink of extinction: the pangolin.

The Hillary Clinton campaign goes solar

With polling that suggests two-thirds of voters want the next president to address climate change, Hillary Clinton has laid out an ambitious renewable energy plan while campaigning in Iowa and New Hampshire.

The present front-runner for the democratic nomination declared she would take action on day one of her presidential term.

An ecosystem is like a giant game of Jenga — remove the wrong piece and the entire structure can collapse. The history of the black-tailed prairie dog and how its elimination altered the landscape of Mexico and the American West powerfully illustrates this principle.

Black-tailed prairie dogs once numbered in the billions across the grasslands of the Western US and Mexico, but ranchers essentially exterminated the rodent to make way for livestock.

To avoid catastrophic global warming, scientists say the world must drastically cut greenhouse gas emissions — and that means slashing the use of fossil fuels. New numbers indicate that the change is already underway.

For the first time in history natural gas is now generating more electrical power than coal in America — a major milestone on the way to rebuilding the energy economy.

Why dying bees may cause a public health problem

Aug 6, 2015

A new study examines the death, disease, and health issues humans might face if a worldwide decline in animal pollinators continues. 

Fruit, vegetables, nuts, seeds, honey: these are all nutrition-rich foods that are produced with the help of animal pollinators, especially bees. In fact, an estimated 35 percent of the world’s food is dependent on animal pollinators.

Mosquitoes are developing resistance to insecticides

Aug 4, 2015

Humans have used everything from screens to chemical repellants to protect themselves from mosquitoes and the diseases they carry. Now, however, scientists say mosquitoes are finding ways to adapt to insecticides and other recent changes in their environments.

A new study on mosquito adaptability has big ramifications for public health workers, and for anyone out on a warm night, trying to avoid both mosquito bites, and the itchiness and disease those bites might bring.

Pacific Northwest sturgeon suffer as worldwide demand for caviar soars

Aug 3, 2015

Caviar, prized as a luxury food, can sell for as much as $200 an ounce. Most caviar comes from the Caspian Sea, but the decline of sturgeon there is driving fishermen and poachers to fish populations in the Pacific Northwest’s Columbia River.

Despite active policing and catch limits on sturgeon, poachers and traffickers still manage to pull black gold from the riverbed, threatening the fish’s survival. Global demand for black market caviar is putting the whole sturgeon population at risk.

Water supply in the West isn’t only about rain, or the lack thereof. A good deal of water scarcity issues have to do with decades-old policy on water issues and entrenched infrastructure.

North America is on fire. Nearly five million acres in Alaska have burned in 2015, and the wildfires are on pace to become the largest ever in Alaska’s history. More wildfires are spreading across Canada, California, Oregon and Washington. Climate change, scientists warn, will only continue to make the wildfires worse.

Nicky Sundt, a climate policy analyst at the World Wildlife Fund, used to work as a smokejumper in the 1980s. He has seen wildfires in North America get continually worse over the last three decades.
