What are truffles, and why do they cost so much? - Carolyn Beans

Dig into the truffle’s unique and mysterious biology to find out what makes them so rare and the limitations of farming them.--Truffles are one of the world’s most expensive foods— in part because global demand often outstrips supply. And truffles are becoming even more rare and more expensive as deforestation and climate change shrink their suitable terrain. But why are these fungi so rare?

Carolyn Beans digs into the truffle’s unique and somewhat mysterious biology.Lesson by Carolyn Beans, directed by Denys Spolitak.Support Our Non-Profit Mission----------------------------------------------Support us on Patreon: http://bit.ly/TEDEdPatreonCheck out our merch: http://bit.ly/TEDEDShop----------------------------------------------Connect With Us----------------------------------------------Sign up for our newsletter: http://bit.ly/TEDEdNewsletterFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagram----------------------------------------------Keep Learning----------------------------------------------View full lesson: https://ed.ted.com/lessons/one-of-the-worlds-most-expensive-foods-carolyn-beansDig deeper with additional resources: https://ed.ted.com/lessons/one-of-the-worlds-most-expensive-foods-carolyn-beans/digdeeperAnimator's website: https://vimeo.com/denysspolitakMusic: https://www.workplaywork.com----------------------------------------------Thank you so much to our patrons for your support!
