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.

Most scientists agree that human interference in the environment has something to do with the recent trend of rising temperatures on the Earth. If we got ourselves in this pickle, what can we do about it?

Though not everyone agrees why the Earth is getting warmer, temperatures are inching up worldwide. A couple of degrees doesn't seem like such a big deal. What difference can a subtle change make?

Recycling proponents tell us that everything that can be recycled should be. Some items, however, can use more energy to recycle than it would cost to make new ones. Are we better off throwing some things away?

The U.N. World Food Programme says more than 1 billion people don't get enough to eat every day. Are crops genetically modified to generate better yields the answer to the world's hunger problems?

If we all paused to look around before beginning to read this article, chances are our eyes would land on plastic. Or our hands would be resting on it as we glanced around. Will anything ever take the place of plastic?

The mighty Romans certainly never thought it would happen to them, but the sun eventually sets on even the most powerful empires. Is there more to the story than war?

Relief wells made the news as a possible method to cut off the Gulf Coast oil leak, but that's not all they're used for. How do these wells prevent and stop dangerous overflows?

Landfills around the world are overflowing with the refuse of daily life. Can we shrink our trash heaps by means other than composting or recycling?

Ocean waste like this discarded net often works its way across thousands of miles, photodegrading and ultimately converging into a swirling vortex big by any standards. Is it possible to clean up the world's biggest landfill?

The ozone layer prevents much of the sun's ultraviolet light from reaching the Earth. But there's a problem: a gaping hole the size of Antarctica. What can we do about it?

Biodynamic viticulture can get downright spiritual with its attention to lunar cycles and other cosmic forces. So why would a vineyard need to pay attention to such things, and what do manure-filled horns have to do with it?

Artificial light lets us stay up through the night or feel secure in the dark. But those midnight noons push our bodies out of whack and confuse the natural world. Is there a fix for light pollution?

Good solutions for congestion are hard to come by. But by using the principles of supply and demand, variable congestion pricing might just be able to clear things up.

Net metering could turn your home power setup into a money maker -- that is, if your state allows it. How can you start charging the electrical grid?

It's the largest machine in the world. Yet despite the sheer size of the U.S. power grid, a few outages can cost Americans at least $150 billion dollars annually. What are we to do? Could the smart grid be the answer?

We're currently suspended between two ages: a time dependent on fossil fuels and a future dominated by renewable energy sources. Yet not everyone is sold on this vision, so a number of myths about renewable energy persist.

They may seem like a fun water sport or a noisy nuisance, but whatever your stance on personal watercraft, there's no denying they pollute. So how bad are they?

Most folks are trying to green their driving to help out the environment (and their wallets). But what is NASCAR doing to clean up its image?

Plastic bags are generally unsustainable. Even if they are biodegradable, they take roughly 1,000 years to fully break down. Minnesota company NatureWorks has come up with a green plastic bag, but how eco-friendly is it?

You'll see biodynamic farmers consulting the moon and scattering the ashes of burned pests and weeds on their crops. Is this alternative type of farming alchemy or a sustainable extension of organic?

Prizes are great way to address technological hurdles -- what with all the recognition, the thrill of the race and the sometimes huge payouts. What are five environmental prizes still up for grabs?

Irish pinot noir? Finish Shiraz? If the world's wine-producing regions start to seem a bit odd, it might be because of global warming's effect on terroir.

Disturbing new reports suggest we've reached the point of no return when it comes to global warming. Are we past a tipping point, or can our efforts still make a difference?

When you're camping, it's nice to have a light in your tent. But lanterns can catch fire and flashlights eventually run out of batteries. Does the sun offer a better solution?

Earth Day 1970 didn't have the low-key feel of today's celebration. It was a time for protest -- some of it violent. How did Earth Day transform from a day of dissent to one of public service?
