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.


Polystyrene -- the plastic used in items ranging from plastic forks to take-out boxes to life rafts -- can be recycled, but not without costs. What does it take to recycle polystyrene?

What's the smartest step you can take to help reduce pollution and live in a more sustainable way?

Global warming, fueled by greenhouse gases such as carbon dioxide, is as real as a Texas-sized drought. While the planet’s temperature has increased just 1 degree Fahrenheit during the past century, Earth’s coldest regions have warmed significantly more.

These days, concerns about health, responsible farming techniques, fair trade practices and genetically modified organisms are just some of the reasons why making your weekly grocery list may seem to require a degree in geopolitical economics or chemistry.

Environmental awareness is at an all-time high. We've moved beyond the message that littering is bad -- today we have Web sites, television programs, documentaries and books examining our impact upon the environment.

There was a time when eggs were eggs, beef was beef and grapes were red or green. Eating locally meant going to the restaurant down the street. Now, farming isn't even just farming – it's industrial or sustainable.

The automobile is one of the most important inventions of the past 150 years. This is not only because it provides convenient personal transport and great independence through mobility, but also because of the problems it can cause.

Transportation is one of the world's leading causes of pollution. In many urban areas, as much as 90 percent of the pollutants in the air come from motor vehicles alone.

Landfills have long been the final destination for garbage, but as they start to fill up, we're left to find ways to reduce our waste. What challenges are involved, and why isn't reducing waste as easy as it sounds?

Greenhouse gases, CFCs, oil guzzling cars and smoke-belching industry. We don't lack examples of environmental threats that have occupied the previous generations.

Although a certain amount of carbon dioxide (CO2) occurs naturally in the Earth's atmosphere, there are several human activities that increase levels of the greenhouse gas.

What is green noise and how could we use it? Learn more about green noise and how we use it in this article.

No one would blame you if you're sick of hearing about carbon. Every day it seems there are news stories about rising carbon levels, carbon emissions and even the search for new carbon-based life forms

What is waste heat capture and how is it saving the planet and our pockets? This article breaks down waste heat energy and exactly why it's so important.

Found in everything from plastic shopping bags to water bottles to adhesives, paints and DVDs, industrial resins tend to have a bad rap when it comes to their environmental impact. Can new, sustainable options turn their image around?

Look around you. How many things that you see have some kind of paint, varnish or finish? Coatings are everywhere -- and getting greener by the day.

There's almost always a "yuck factor" involved when you're talking about reclaimed water. But how does that factor change when we add food into the equation?

You may never have heard of rare earth elements, but they're the force behind today's high-tech gadgets, plus a lot of green technology. Are there any environmental downsides to their use?

Bioplastics, or plastics derived from plant materials, can help alleviate many of the pollution problems that regular plastics create, but this eco-friendly alternative isn't an environmental panacea.

You probably think all parasites are disgusting little critters, but that's not always the case. Several are actually critical to the planet.

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?
