Bethel College Professor of Mathematics Kevin Drury recently collaborated with a team of biologists and economists from various universities to research “tipping points” appearing in the environment. Their research will appear in the Proceedings of the National Academy of Sciences (PNAS).
The authors define “tipping points” as qualitative changes in an ecosystem that often result in reduced ecosystem health and are difficult and costly to reverse. This is increasingly concerning for environmental scientists. The team suggests that people, governments and institutions that shape the way people interact may be just as important for determining environmental conditions as the environmental processes themselves. The authors point out many instances of tipping points that resulted in catastrophic changes in ecosystems, such as climate change, collapsed freshwater and marine fisheries and changes wrought by invasive species.
