In this talk, Yun-Tzu (Allison) Lin explains why climate change and nuclear weapons are among the most pressing issues facing humanity. She shares her own experiences to show what young people can do to safeguard our future. Yun-Tzu, a junior at Canadian Academy, is passionate about pursuing climate justice and nuclear abolition. She is excited to speak on the responsibility and power of youth to tackle the pressing issues of climate change and nuclear war. A school strike once sparked her determination to work with like-minded youth to deal creatively and effectively with these existential threats. Since then, through conversations with researchers, policymakers, and atomic-bomb survivors, she has grown increasingly concerned about the urgency of climate and nuclear threats. By sharing her understanding of the two threats and her experiences with youth activism, she hopes to inspire others to find their own motive and confidence to act.
