Welcome back, everybody.

We've actually got some really fun stories for you today.

I'm Callie.

Today, you'll learn about a more sustainable jet fuel made from trees,

how a new process allows you to 3D print glass and why feeding coral reefs might save

them from heat stress.

All right, let's get into it.

By some estimates, for every kilogram of jet fuel burned, over three kilos of CO2 are produced.

Meanwhile, global aviation fuel consumption is nearing 100 billion gallons every single year.

In other words, the fuel that takes us skyward is a pretty huge contributor to climate change.

So I read somewhere that in the past 30 years or so, the amount of flying we do has nearly quadruple.

That includes freight and shipping, obviously, but it is a huge leap. And while fuel efficiency of our jets

has increased pretty dramatically, it's estimated that aviation accounts for around 2.5% of the world's

CO2 emissions. That's why there's been a race to find a new path. Totally. And you can't go on

social media these days without seeing some crazy video of an electric plane prototype or reading
