Hi, I'm Lindsay.

And I'm Marshall.

Welcome to tumble the show where we explore stories of science discovery.

This is our fifth and final episode of Life Lab, our series about how tiny life can change

everything.

In the last episode, we heard about a future where we wear wild new clothes made by biology.

We're talking spider silk and mushroom leather.

So listen to that episode if you haven't already.

But fashion is only one piece of how we could make a better future on our planet.

In this episode, we'll tackle the big one, climate change.

And we'll find out how a bacteria from a bunny's belly could turn our worst waste into our

greatest resource.

We made it to the final episode of Life Lab.

And now I've taken my team of Crack Square astronauts to Mars.

We've got mushroom pants.
