Second Major in Sustainability
We live in a time of large-scale challenges, where climate change, deforestation, biodiversity loss and ocean acidification are no longer only considered from an environmental perspective, but also in terms of social justice, economic development, technological adaptation, and political will. The survival of our growing population depends on the natural resources we continue to overexploit, but there is increasing awareness on how the concept of sustainability strives to address this. By understanding how our environment, economy and society interact, applying this to technological innovation and communicating readily with decision makers, we can maintain the health of our world for the benefit of current and future generations.
