Viral Shah, an Indian computer scientist and co-founder/CEO of Julia Computing, highlights how computation, particularly his Julia Language, can solve major climate change issues. Julia, a high-impact language, defies the notion that productivity and performance are mutually exclusive in programming. He encourages students to use computation for social impact and global problem-solving.

Shah's contributions extend to the Aadhaar Project and co-authoring "Rebooting India." His work on the Julia Language earned him the 2019 J. H. Wilkinson Prize, and he received the 2013 SETWG award for co-creating Circuitscape. This talk was presented at a TEDx event. Learn more at https://www.ted.com/tedx.

In her reflection titled "Disconnection," Julia Butterfly Hill introduces "separation syndrome" as the fatal consequence of severing our ties to life. She illustrates this by noting that a plant dies when its roots are ripped from the earth, mirroring how humanity perishes when we detach from our connected consciousness.

Hill argues that this profound disconnection leads to the demise of our planet, our human families, and the entire global family. Her message underscores the critical importance of recognizing and nurturing our interconnectedness for collective survival.
