Jinmoo Yoo explores how commonly held assumptions about the 'keys to climate change' may be holding us back from making real changes. Instead, he demonstrates how a personal project enlightened his belief that data science can lead us towards strategies that are more accurate, specific and effective in remedying human behaviours that damage our environment. Jinmoo Yoo is an IB Diploma student at Hanoi International School, Vietnam, an IB World School. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx
