It's the first plant plant of its kind in the states that generates electricity from the temperature differences in the ocean.

This short film, while focused on the island of Kauai, highlights the challenges and crises we will all have to face on our island planet.

This is candy in its purest form -- certified organic ingredients, zero artificial colors and flavors, no preservatives or GMOs.

As if to say 'sorry,' Kilauea softens its fury by tossing shimmery green olivine to the humble humans below.

A wholphin? A dolphale? Whatever you call it, the first known hybrid between a melon-headed whale and a rough-toothed dolphin is a wonder.

There are huge gains to be made by boosting efficiency. Even if we can never get to 100% because of the laws of physics, we could get much closer than we are now.

Most of us alive today owe a debt to those who avoided nuclear war in years past, and sadly, there were many occasions when that was necessary.

Tons of jellyfish clog a water intake pipe at the Oskarshamn power plant in Sweden, forcing operators to shut down the reactor.

We still need a ton more renewable energy in order to combat climate change, but the good news is that renewable energy is picking up the pace.

If your price doesn't reflect the true cost of your product, then there's no such thing as a free market.

MIT design cuts fusion reactor down to a size that would be more cost effective and could be built in five years

The number of wolves alone around Chernobyl is more than 7 times greater than can be found in other nature reserves.

Mushrooms and game meat in European regions where Chernobyl fallout was most intense still have excess radiation, but Burgundy truffles get the green light; foodies rejoice.

Earlier research found evidence of a wildlife wonderland at the disaster site, now the first camera study validates an abundance of wolves, boars, foxes and more.

The technology turns the problem of nuclear waste into a source of safe nuclear energy.

Instead of building giant concrete buildings filled with uranium, why not build smaller energy-efficient buildings filled with people.

This is, in fact, one of the things that e-bikes are really good at. Another dumb move.

Eben Weiss, the Bike Snob, is an unexpected source for this proposal to save the environment.

From mislabelling to plastic contamination, eating fish isn't as safe or healthy as most diners would like to believe.

These coolest of sea creatures know what they're doing.

This young startup uses cellular agriculture to grow fish out of water -- delicious, nutritious, and cruelty-free.

Tangled in fishing line with things looking grim, the story of Frito's rescue is inspiring all around.

Company higher-ups sold stocks while telling investors that everything was fine.

Scientists argue over whether some animals have the brains for suffering.

It takes the controversial stance that more fish doesn't necessarily mean better fish.

The recent UN biodiversity report states that overfishing is a bigger threat to the world's ocean than plastic or acidification.

If it weren't for an added colorant, it would be grey or white like most of the other fish on display at the store.

The Guardian columnist and environmental thinker George Monbiot usually manages to provoke a strong debate in our comments sections. Some time ago, our post on his new book Heat raised a fierce exchange of views about the impacts of flying, meanwhile his

In his erudite analysis of the global warming issue, Don Blankenship of Massey Coal expressed his opinion about the future of polar bears:

In the UK and Canada, manufacturers are urging the government to give consumers money to get old cars off the road and into newer, lower emission vehicles and "catalyse a new low carbon transport revolution." George

George Monbiot is at it again, causing controversy by saying "Environmentalism may be emotional but it should always be based on science, not like the wishful thinking behind natural remedies."-Environmentalism must be fact based and there is no room

George Monbiot told us that flying is dying; London artist Richard DeDomenici tells us that a return transatlantic flight is equivalent in CO2 and pollution output to driving a car 30 miles a day for a year. So the artist/humorist has
