Tali had two assignments for school: Earn $150 towards the school field trip, and support a cause. He decided to try busking, and of course he chose the cause closest to his heart: Trees. He'd never tried busking before, but at the end of this first day he said "I loved it! I don't even care about the money - I just love to see all the people smiling."
When he has busked enough that 40% of his earnings equal $150, he will bring that to his school, and donate the remaining 60% to the Ancient Forest Alliance.
