Trees have proven to decrease carbon in our atmosphere, keep cities clean, and even reduce anxiety … but how exactly do they do it? Dan takes us behind the bark to understand the anatomy of our gentle green giants and how every root, leaf and twig work together to improve our planet, and what we can do to help support them in the fight against climate change. 

TED Climate is produced and edited by Sheena Ozaki, mixed by Sam Bair, and hosted by Dan Kwartler. This episode adapted two lessons originally produced in animated form by the TED-Ed team. “What if there were 1 trillion more trees?" was written by Jean-François Bastin. "What happens if you cut down all of a city's trees?” was written by Stefan Al. Both pieces were produced with editorial support from Alex Rosenthal. Special thanks to Gerta Xhelo, Stephanie Lo, Michelle Quint, Banban Cheng, and Anna Phelan.

What if there were 1 trillion more trees on the planet?

We get it. You care about the climate crisis—but sometimes thinking about it is just too overwhelming. Well, we’re here to help with that. Host Dan Kwartler unpacks the problems and solutions behind big systemic issues in bite-sized episodes. You’ll find out which bag is best for the planet, imagine our world without humans, and follow the international journey of the very shirt on your back. Yes, we’re going to talk about the bleak stuff—it’s a crisis after all—but we’ll also share little ways you can make changes in your daily life, in your towns and cities, and at your workplaces to help change climate change. Ultimately we’re aiming for some HOPE through a focus on solutions, instead of just, you know, tumbling towards inevitable doom.

The single most important thing for avoiding a climate disaster is cutting carbon pollution from the current 51 billion tons per year to zero, says philanthropist and technologist Bill Gates. Introducing the concept of the "green premium" — the higher price of zero-emission products like electric cars, artificial meat or sustainable aviation fuel — Gates identifies the breakthroughs and investments we need to reduce the cost of clean tech, decarbonize the economy and create a pathway to a clean and prosperous future for all.
