Green Science

Green Science is the application of eco-friendly thinking to scientific disciplines. Learn about global warming, pollution and other impacts on nature and the planet, plus what we can do to combat them.

Electrifying dance moves might impress your friends, but they usually don't help power the club you're dancing in. What's piezoelectricity, and how could it help twist the future of energy generation?

Sure, the Emerald City looked green, but you won't need green-tinted glasses to see how environmentally friendly the cities on this list are. What makes a city amazingly green?

Usually we're focused on our personal power consumption -- wondering why our gas bill went up or took a dip. But what if we added up everybody's power consumption? How much would it be?

Many people think that beautiful, blazing sunsets are one upside to living with the smog that hangs over polluted cities. Are they right? Does smog actually enhance sunsets?

L.A. and ancient Rome have more in common than a culture of excess. Both cities turned to complex systems of siphons and aqueducts to solve their water problems.

Depending on who you ask, urban sprawl is either the best thing that ever happened to growing families -- or the downfall of civilization and the environment as we know it. Learn about the history and consequences of this American phenomenon.

There's no transdermal patch to help the United States end its addiction to oil. As gas prices rise and pollution spreads, can anything break our gasoholic tendencies?

A high demand for lumber and paper can lead to deforestation, which can deplete forests, threaten wildlife and contribute to global warming. That's where the Forest Stewardship Council certification comes in.

Are multipurpose plastic bags or those throwback brown paper bags more environmentally friendly? That question could leave you speechless on your next trip to the grocery store.

For those who reduce, reuse and recycle to the beat of their own drum, here are some of the wackier ways to help better the environment and lessen carbon footprints.

For all of its cleanliness, wind power has long been linked to the grisly deaths of birds. Why did one range in California earn turbines the name "bird-o-matics"?

When vying for its Olympic bid, Beijing promised that it could stage a green games. So what makes an international event "green," and what's Beijing doing to prepare for its debut?

As alternative energy sources sputter to take off on Earth, scientists are turning an eye toward space. What are the most promising celestial options, and when could they be in use?

Many oil companies claim to have cleaned up their act. But are they clean enough to set up shop on federal land? What are the risks of opening our preserved wilderness?

What if you could scrub out carbon dioxide emissions before they ever dirtied the atmosphere? This exciting technology could do just that, but will the benefits outweigh the costs?

Some scientists think that the ocean is a potentially enormous storage ground for carbon dioxide. Could thousands of aquatic tubes help sequester carbon, or is it all just a pipe dream?

If, in a few years, you begin to see scores of blimps floating overhead, don't be alarmed. They're MARS turbines, and they could be an aerial solution to the energy problem.

Are wind farms and other renewable energy sources the closest we can come to free energy? Isn't there some crackpot invention out there that you can set up in your backyard?

Environmentalists have found a way to harness the military precision of missile-tracking technology for a decidedly nonviolent mission: replanting forests. So what do C-130 aircraft have to do with reforestation?

In this mass graveyard, workers dismantle 52,000-ton ships using simple hand tools. Why would anyone want to work at Alang? Is this place doing the world a service by recycling obsolete ships?

That water bottle shoved in your bag may be providing you with more than just a cold drink. Do you know what chemical you're washing down with that water?

We know that we fuel global warming with our carbon emissions. What if we could seize all that carbon and squirrel it away in a safe place? Well, we can.

Wetlands may look murky and even creepy, but their value is clear. They soak up floodwaters and filter runoff before it enters our lakes and streams. How can we protect these spongy areas?

Our big cars and big appetites are taking a big toll on the environment. Overconsumption contributes to the depletion of Earth's resources, and some countries are taking more than their share.
