Can a tree help you be smarter? This week we dive into that question and discuss how air pollution effects our brains, and how trees can help keep us operating at our top level. After our rating, we head LIVE to the Grand Finale of the Tournament of Champion Trees with Tobin Mitnick (@jewslovetrees).

7 Deadly Stems: WRATH (Bullhorn Acacia)

The common fig (Ficus carica): one of humanity’s first food obsessions. From covering Adam’s junk to covering other Eve’s junk, this plant has no shortage of cultural import. But does it deserve the valor it’s flaunted for hundreds of years?

7 Deadly Stems: SLOTH (Weeping Willow)

We are honored to be joined by author, illustrator, and overall bird-and-tree-advocate DAVID ALLEN SIBLEY! We talk to David about his process, whether he's an artist first or a bird lover first, and have him describe a bird perpetrator to us as we sketch from his description!
