Between the years 2030 and 2050, a quarter of a million people per year will lose their lives to climate change. Blazing temperatures and catastrophic weather are well-known climate change effects, but these simply do not compare with health-related effects: the transmission of water-borne and vector-borne disease. Seventeen-year-old high schooler Arjun Marwaha has committed himself to foster awareness for climate change among the youth of today. In Our Changing Earth, he delves into how our planet will be altered in response to climate change, and why this is relevant particularly to young people. Looking forward, Arjun hopes to promote awareness among all humans for the greatest threat to humanity in the 21st century and beyond: climate change.
