Where are the best places to live if global warming gets the best of us?

If temperatures continue to rise in the face of human-induced global warming as climatologists expect, some of the world’s most populous areas could become uninhabitable.


What is the Great Green Wall of China?

Unlike the Great Wall of China, a 5,000-mile fortification dating back to the 7th century BC that separates northern China from the Mongolian steppe, the Great Green Wall of China—otherwise known as the Three-North Shelter Forest Program—is the biggest tree planting project on the planet.


How can teachers integrate sustainability topics into the classroom?

Teaching our kids about sustainability and green living is one of the most important things we can do to safeguard the future of humanity and the planet we inhabit.


Earth Talk: Should I recycle my disposable batteries?

Truth be told, those old used up disposable alkaline batteries (AA, AAA, C, D, 9-volt, etc.) aren’t the environmental menace they used to be before the federal government mandated taking out the mercury, a potent neurotoxin linked to a wide range of environmental and health problems, as part of the Mercury-Containing and Rechargeable Battery Management Act of 1996.

Are we past the point of no return on climate change?

While we may not yet have reached the point of no return—when no amount of cutbacks on greenhouse gas emissions will save us from potentially catastrophic global warming—climate scientists warn we may be getting awfully close.


Is backyard firepit smoke a health hazard?

With summer approaching, many of us are eagerly anticipating the first night we can gather with loved ones under the stars around our backyard firepits.


Helping prevent Amazon deforestation

Most if not all deforestation is ultimately driven by our consumption, so avoiding products and companies responsible for deforestation is the logical first step.


Energy East: Worse than Keystone XL?

The Energy East Pipeline is a $12 billion project proposed by TransCanada Corp. that will combine existing, converted natural gas pipelines with new pipeline construction to carry oil some 2,800 miles across Canada from Alberta’s tar sands fields to export terminals in Quebec and New Brunswick.


Seeding our oceans

Ocean fertilization is a technique whereby swaths of ocean are “seeded” with iron to promote the growth of phytoplankton (microscopic plants that form the base of the marine food chain), and is one of several promising geo-engineering techniques that could help mitigate global warming.


Solar: Uncertain future?

In the U.S., a new solar project was installed every three minutes in 2014, and jobs in the solar industry rose from 15,000 employees in 2005 to nearly 174,000 today.


Earth Talk: Safe insulation

Making your home more energy efficient is certainly good for the planet and will cut your heating/cooling bills, but you’re right to worry about chemical off-gassing.


Earth Talk: Blizzard of e-waste

With a record four million pre-orders for Apple’s best-selling iPhone 6 and iPhone 6 Plus, it’s more evident than ever that consumers want the latest in smartphone technology at their fingertips.


Divestment and fossil fuels

The climate movement has embraced divestment—that is, ditching stocks, bonds or investment funds deemed unethical or morally ambiguous—given how effective the tactic was in helping topple Apartheid in South Africa by shaming the companies still willing to do business there.


Health impact of coal

Coal combustion plants account for more than half of Americans’ electric power generation. According to Coal’s Assault on Human Health, a report by the non-profit Physicians for Social Responsibility (PSR), coal combustion releases mercury, nitrogen oxides, sulfur dioxide and other substances known to be hazardous to human health.


Moms Clean Air Force: Naptime activists unite!

Moms Clean Air Force (MCAF) is a community of 400,000+ parents working to combat air pollution and respond to the climate change crisis.


Sunscreens get safer

The ingredients in some common chemical-based sunscreens are known to cause allergic reactions for some people and have been linked to reproductive and behavioral problems in animal studies.


Televisions bigger and greener than ever?

According to the U.S. Department of Energy, Americans’ 275 million television sets burn through some 65 billion kilowatt hours of energy each year, representing four to five percent of U.S. household electricity consumption.


Microbeads and marine pollution

Can brushing your teeth or using an exfoliating face or body wash be an act of pollution? Perhaps so, because over 1,000 personal care products contain tiny plastic “microbeads,” each about a half millimeter in diameter.


Better living through conservation genetics

Traditionally, conservation biologists have relied on field observation and sample and statistical analysis to help them understand the dynamics behind species loss.


What fish can we eat?

Between mercury poisoning, overfishing and the environmental impacts of fish farms or “aquaculture,” some might expect to see a “Proceed with Caution” sign above seafood counters soon.


What is being done to protect grizzly bears?

Before European colonization of North America, upwards of 50,000 grizzly bears—also known as brown bears—roamed free across what is now the continental United States.


Moving beyond flame retardants

Putting flame retardants in furniture seemed like a good idea back in the 1970s to help protect against the risk of fire, but our insistence on safety has come back to haunt us.


Assessing the risks of genetically engineered crops

Earth Talk examines the potential health and environmental impacts of so many genetically engineered organisms in our food supply.


Earth Talk: Should plastic bags be banned?

California made big news recently when it announced the first statewide ban on plastic shopping bags set to kick in during the middle of 2015. Beginning in July, large grocery stores, pharmacies and other food retailers in the Golden State will no longer be able to send shoppers home with plastic bags, while convenience markets, liquor stores and other small food retailers will join the ranks a year later.
