Most of us can agree that reducing greenhouse gas emissions is a must given the rapid warming of the planet; just how to do it best is another question entirely.
Solar desalination is a technique used to remove salt from water via a specially designed still that uses solar energy to boil seawater and capture the resulting steam, which is in turn cooled and condensed into pristine freshwater. Salt and other impurities are left behind in the still.

But if paint can no longer be used, what are some safe, environmentally-responsible ways to dispose of it?
While no one questions that California is in the midst of one of the worst droughts in recent history, the jury is still out as to why, at least according to some conservatives like former Hewlett Packard CEO and 2016 Republican Presidential hopeful Carly Fiorina.
Non-human rights is a term coined by animal welfare activist and lawyer Steven Wise, who has campaigned for three decades to achieve actual legal rights for members of species other than our own.
Ah, the summer road trip, that classic American experience. But long drives through steamy weather can burn through a lot of gas and cause untold wear and tear on your car’s engine and systems while putting you at risk for overheating.
Junk mail has increased to a massive scale in recent years, with the average American receiving 16 pieces each week. While this might not seem like much, it adds up to weigh an estimated 41 pounds each year, according to leading anti-junk mail organization, 41pounds.org.
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.
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.
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.
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. T
April 22, 2015 is the 45th annual celebration of the first Earth Day in 1970, when 20 million Americans took to the streets, parks and auditoriums to demonstrate for a healthy, sustainable environment in massive coast-to-coast rallies.
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.
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.
Most if not all deforestation is ultimately driven by our consumption, so avoiding products and companies responsible for deforestation is the logical first step.
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.
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.
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.
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.
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.
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.
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.

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.
Fuel cell cars have not caught on and skeptics wonder if they ever will. One big hurdle is that creating hydrogen fuel turns out to be highly inefficient compared to other readily available fuels.
Dr. Henry I. Miller, former director of the Office of Biotechnology at the U.S. Food & Drug Administration, argues that conventional farming—which uses synthetic pesticides, herbicides and fertilizers and often genetically modified (GM) seed stock to maximize yields—is actually better for the environment, producing more food and using less water compared to organic farming.
Hydroelectric sources of power dwarf other forms of renewable energy, but wind power has been a dominant second for years, and continues to show “hockey stick” growth moving forward.
Kids today may be more eco-savvy than we were at their age, but complex topics like climate change may still mystify them. Luckily there are many resources available to help parents teach their kids how to understand the issues and become better stewards for the planet.
Carbon dioxide emissions are indeed lower than at any time since 1994, according to data recently released by the U.S. Energy Information Administration (EIA). But if you think that the rise of the hybrid car, our embrace of public transit, walking, biking and those new windows on the house are behind the trend, think again.
