Today is Earth Overshoot Day, but it's not exactly something we should be celebrating. It's actually a wakeup call for humanity.

Population growth is in fact slowing down but everyone is using more of everything.

If the latest projections prove to be accurate, we need to plan for about a 10% increase in the needed supply of food, drinking water, and energy, and in carbon dioxide emissions by 2050.

Annual growth will soon be negative everywhere except Africa.

The number is probably far higher than you think.

Pollinator power, y'all.

Many vegans don't realize that there's 'meat' in their electricity supply.

The Bay Area needs affordable housing. And it needs clean energy. A new campaign supports both.

Move over, regular solar panels.

Primary energy consumption was down, too.

There's symbolism here. Let's hope there's substance too.

Buying products from solar farms is just one more way to support clean energy.

Now that's progress...

It's an important inflection point. But a lot of work still remains.

Home owners are going solar, without having to put anything on their roof.

Stanford scientists figure out a way to get hydrogen out of seawater. Does this matter?

In the first half of 2019, Scottish wind generated enough electricity to power the equivalent of 4.47 million homes, almost double the number of homes there.

Sometimes we should just let a bad idea die.

After all, who wouldn't want a glass of "pure glacial water filtered through lava"?

Thirty bottles will buy you a ticket on the subway or bus.

The styrofoam substitute that they grow into packaging and insulation is the next big thing in building.

Combining computer-aided parametric design and the design principles of tensegrity (tensional integrity), this experimental pavilion tests the boundaries of building a stronger structure with less material.

Domes are tough. Here is a design that tries to make them comfortable. Does it live up to its billing?

Bourgeois / Lechasseur architects figure out how to square the circle.

A new kind of food label hopes to fight obesity by stating how much exercise is required to burn it off.

Every company should have to do this– more useful information that consumers need.

Some useful tools for working on a 1.5 degree lifestyle.

A taste-test between the two kinds of fat had a surprising outcome.

The gaze between human and dog can share physiological properties similar to that of mother and infant, a new study finds.

The last of these dog-like animals, also known as Tasmanian tigers, was thought to have died in 1936. But might they still be lurking elusively in the wild?

The mapping technology will eventually be used to get precise solar power potential information for any location around the world.

This new map uses satellite technology to display the world's vegetation, and can be used for everything from weather predictions to deciding best land use practices.

The new map was created from a study of over a decade's worth of Landsat satellite images and is the first to show in fine detail land use changes around the globe.

The software lets you virtually float down the Yampa River, which has been largely unchanged by man.

The overhaul now includes the Voyager feature for deep exploration, not just satellite views.

A concept water bottle pulls water from the air like the Namib Desert Beetle.

One solution for purifying water in remote off-grid areas comes in the form of a wagon, complete with solar panel and water purification system.

As you can see in the satellite photos above, California is experiencing a massive drought over most of the state. The most visible aspect from space is the snow cover (or lack thereof) over the Sierra Nevada mountain range

The ÖKO Odyssey water bottle actually has six functions!

California has been going through a drought for about 3 years now, with 2013 being the driest year on record.

It's time we made water bottles part of our every day carry (EDC) kit. This handy little bottle squishes down small enough to go everywhere you do.

You may think you're ingesting a safe, clean product, but you're really putting synthetic microfibers into your body.

Times they are a changin'

Why are we wasting such a valuable resource? Where will it come from if we don't drill for natural gas?

We are by no means helpless in the face of climate change.

A new study suggests we look to the past for guidance on how to cope going forward.

With a warming climate, the remains of unlucky mountaineers are beginning to rise from the ice.

In which we tackle one of life's more pressing queries.

What's in a cricket's song? And how do they do it?

George Monbiot wades into the meat-and-climate debate by explaining how 'ethically' raised meat is actually worse for the planet than those raised in confined spaces. It leaves omnivores in an awkward position.
