TED- We’re covered in germs. Let’s design for that.

Our bodies and homes are covered in microbes — some good for us, some bad for us. As we learn more about the germs and microbes who share our living spaces, TED Fellow Jessica Green asks: Can we design buildings that encourage happy, healthy microbial environments?

TED- How we’re growing baby corals to rebuild reefs

Kristen Marhaver studies corals, tiny creatures the size of a poppyseed that, over hundreds of slow years, create beautiful, life-sustaining ocean structures hundreds of miles long. As she admits, it’s easy to get sad about the state of coral reefs; they’re in the news lately because of how quickly they’re bleaching, dying and turning to slime. But the good news is that we’re learning more and more about these amazing marine invertebrates — including how to help them (and help them help us). This biologist and TED Senior Fellow offers a glimpse into the wonderful and mysterious lives of these hard-working and fragile creatures.

 

TED- Climate change is happening. Here’s how we adapt

Imagine the hottest day you’ve ever experienced. Now imagine it’s six, 10 or 12 degrees hotter. According to climate researcher Alice Bows-Larkin, that’s the type of future in store for us if we don’t significantly cut our greenhouse gas emissions now. She suggests that it’s time we do things differently—a whole system change, in fact—and seriously consider trading economic growth for climate stability.

 

TED- Why climate change is a threat to human rights

Climate change is unfair. While rich countries can fight against rising oceans and dying farm fields, poor people around the world are already having their lives upended — and their human rights threatened — by killer storms, starvation and the loss of their own lands. Mary Robinson asks us to join the movement for worldwide climate justice.

 

TED- The state of the climate — and what we might do about it

How can we begin to address the global, insidious problem of climate change — a problem that’s too big for any one country to solve? Economist Nicholas Stern lays out a plan, presented to the UN’s Climate Summit in 2014, showing how the world’s countries can work together on climate. It’s a big vision for cooperation, with a payoff that goes far beyond averting disaster. He asks: How can we use this crisis to spur better lives for all?

 

TED- Let the environment guide our development

Human growth has strained the Earth’s resources, but as Johan Rockstrom reminds us, our advances also give us the science to recognize this and change behavior. His research has found nine “planetary boundaries” that can guide us in protecting our planet’s many overlapping ecosystems.

 

TED- Debate: Does the world need nuclear energy?

Nuclear power: the energy crisis has even die-hard environmentalists reconsidering it. In this first-ever TED debate, Stewart Brand and Mark Z. Jacobson square off over the pros and cons. A discussion that’ll make you think — and might even change your mind.

 

 

TED- The science behind a climate headline

In 4 minutes, atmospheric chemist Rachel Pike provides a glimpse of the massive scientific effort behind the bold headlines on climate change, with her team — one of thousands who contributed — taking a risky flight over the rainforest in pursuit of data on a key molecule.
