This document discusses why students should study environmental science. It notes that Nepal's population has grown enormously over time from 1.45 million years ago to nearly 30 million currently, placing increasing pressure on natural resources. Charts show declines in some wildlife species in Nepal, like tigers dropping from 155 to 98 from 1995 to 2010. The document advocates for sustainable livelihood activities, like mentha and marmelos juice production, and alternative energy sources to reduce pressure on forests while improving health. It concludes by asking students to consider which future world they want and their role in shaping it through environmental science.
