Remediation technologies work to decrease pollutants in the air, soil and water. Learn how we may be able to undo some of the damage that we've done to the environment.
The controversial technology of reflecting sunlight away from the planet could help blunt the worst impacts of climate change. Harvard University climate scientist David Keith weighs in.
Coral grows faster when it's cut or broken and scientists are taking advantage of that to replenish depleted reefs.
As sea levels rise with climate change, beaches are losing ground against ever-encroaching waters. Trucking in sand may seem like a good idea, but the evidence, while not yet conclusive, may show otherwise.
People have floated the idea of towing icebergs to drought-stricken parts of the world for years. Sounds like a good idea, but how viable is it?
There's no easy fix for climate change so scientists are playing with altering the Earth's natural systems in hopes of slowing it down. What could possibly go wrong?
Human attempts to alter the Earth's natural systems could either successfully avert climate change or fail and cause even greater harm.
Scientists are tickled pink about all the environmental uses for the orange peel.
For plenty of people, getting a drink of water on the hottest of days is not as easy as filling a glass at the tap. The Slingshot aims to do something about that.
If the planet is truly warming, we could be in for some catastrophic results, according to some scientists. It's no wonder that a few are theorizing some dramatic methods to cool the Earth's surface.
Many of us take clean water for granted, but hundreds of millions of people have no access to it. Luckily, technologies like LifeStraw can help make water safer for individuals and families who desperately need it.
Gleaming from beneath the water's surface, you spy a large fish speckled with scales of sapphire. What could it be? Would you believe a pollution-sniffing robot?
There's nothing that innovative about a tricycle or a water filtration system -- but when the two are combined, it's a different story. The Aquaduct Mobile Water Filtration Vehicle might be the answer to water scarcity and contamination.
