"In the world in which we live today, sustainable development is unavoidable. Without sustainable development, the next generation will not be able to have the same living standard which we currently enjoy. Nature suffers from overuse and will be the loser without sustainable development. My goal for the future is that we find a way to live more sustainably and in equilibrium with nature. For those reasons, I decided to study environmental science and have been an active member for the last two years of [project 21], the student organization for sustainable development at the ETH and the University of Zurich."
