Big Picture Science – On Thin Ice

Water is essential for life – that we know. But the honeycomb lattice that forms when you chill it to zero degrees Celsius is also inexorably intertwined with life.

Ice is more than a repository for water that would otherwise raise sea levels. It’s part of Earth’s cooling system … a barrier preventing decaying organic matter from releasing methane gas … and a vault entombing ancient bacteria and other microbes.

From the Arctic to the Antarctic, global ice is disappearing. Find out what’s at stake as atmospheric CO2 threatens frozen H2O.

click to listen!

It’s not just tin cans and newspapers. One man says that, from a technical standpoint, everything can be recycled – cigarette butts, yoga mats, dirty diapers. Even radioactive waste. You name it, we can recycle it. But we choose not to. Find out why we don’t, and how we could do more.

Plus, a solar-powered device that pulls water from the air – even desert air.

And, something upon which life depends that seems dirt cheap, but can’t be replenished: soil. What happens when we pave over this living resource?
