Plastic's handy, hardy stuff, but we don't want to leave piles of old forks and water bottles for future generations to trip over. Can special additives that break down plastics faster save the day?

You may have heard of absorbents before, like sponges and paper towels -- but what about adsorbents? And how can they help clean up environmental disasters?

Invasive species are found around the globe, and their presence outside of their native areas is damaging the world's ecosystems and threatening biodiversity. Some -- like the five on this list -- seem almost unstoppable.

If you're like most people, you probably assume "organic" means no insecticides. But it's not really like that. What do organic farmers use to kill pesky insects?

When you think about it, space travel requires an energy-efficient approach, especially if you're going to make it to another planet. What green technologies are essential for space travel?

Sunlight can break plastic down but not very fast. Is there a way to speed up the process so that natural environments like this one aren't cluttered with plastic debris for centuries?

The green movement isn't going to die just because the world ends. In fact, sustainable types might even have a leg up post-apocalypse. Here's how.

There's no way around it: The world is currently gripped by a global energy crisis. As scientists scramble for answers, hydrogen energy has emerged as a great, yet flawed solution.

As two of the most important elements to the sustenance of life on Earth, the sun and water are forever intertwined. Just to name one example, the sun's energy can be used to make water palatable to those who wouldn't be able to drink it otherwise.

Researchers have been working hard over the past several years to develop new forms of alternative energy that are both cheap and environmentally friendly. Is there one fuel in particular that will save you the most?

In the wake of the financial crisis, the corporate sector has turned its eye towards green energy -- the kind that's clean and sustainable. What steps have businesses taken to drive the growth of this new market?

U.S. President Barack Obama has cited clean energy as the key to economic recovery, but how is the nation promoting clean energy research domestically? It turns out that there's a government office that's already on the case.

If you've ever held two magnets close together, you've probably felt their surprising force. Has anyone figured out how to convert that energy into an alternative power source?

Tourism is one of the world's largest exports, but it can often leave the locals with the short end of the stick. Sustainable tourism helps visitors use their vacations to have fun in ways that benefit the local economy and ecology.

As the world deals with a global food crisis, farmers need to figure out how to grow crops in a clean and sustainable way. What does sustainable agriculture accomplish that conventional farming can't?

The world's forests hold some of its most precious natural resources -- its trees. Sustainable forestry encourages attention to the forests' long-term health so they retain their value.

In the race to find alternative energy sources, wind power is a strong contender. In fact, it's already making its mark. How much do you know about this up-and-coming energy source?

Not only do cars produce a large portion of the world's pollution, but airplanes, boats, trucks, trains and buses also contribute to pollution. Is there one magic solution to pollution?

That's the goal for these minuscule technologies with their array of seemingly miraculous materials, supernatural conductivity and paranormal photonics. Can you name one?

While the specifics vary from one industry to the next, there are several generally accepted principles of green engineering that are universal. How much do you know about the discipline of green engineering?

Most scientists agree that man-made climate change is a real phenomenon, but most people respond to their dire warnings by figuratively sticking their heads in the sand. Could the problem lie in the severity of their message? In other words, are we scaring people into inaction?

Shopping may put a dent in your wallet, but it doesn't have to harm the Earth. Here are tips on keeping the environment in mind as you roam the grocery aisles.
