That was the topic of the season finale of Institute on the Environment’s Frontiers in the Environment lecture series on Wednesday, May 7, on the University of Minnesota’s St. Paul campus.
In “A Watershed Approach to Understanding Urban Eutrophication,” Sarah Hobbie, an IonE resident fellow and professor of ecology, evolution and behavior in the College of Biological Sciences, discussed how nutrients from lawns, pets and boulevard trees contribute to excessive algal growth in urban water bodies.
Last fall, 10 other people and I paddled more than 2,000 miles in canoes. Our trip was called Paddle Forward, and we were on a mission to paddle the length of the Mississippi River.

I spent the majority of college learning about environmental issues surrounding climate change, such as energy usage, water depletion, resource extraction and decreases in biodiversity. Alone, secluded in serene wilderness, you are less likely to think about difficult climate issues. However, while paddling a river that more than 50 cities depend on for daily water supply, you can’t escape noticing the effects humans have on the fourth largest watershed in the world.
