I would like to share a press release from the University of Minnesota I received a few days ago announcing a short video on environmental sustainability.
Press release as follows:
Greetings from the University of Minnesota’s Institute on the Environment.
For 10,000 years, our world seemed endless. The sky was the limit. But today’s world looks much smaller. We’ve cleared, consumed and polluted our way across the globe. The planet is shrinking. Have we pushed Earth past the tipping point? That’s a critical issue we explore in our second Big Question video, which draws on research from “Planetary Boundaries: A Safe Operating Space for Humanity,” published this past fall in the journal Nature.
View the video here:
Featured as part of the cover story of Scientific American magazine’s April issue, which hit newsstands on March 24, U of M professor Jon Foley makes the case for why we need to pay more attention to all environmental processes that contribute to the Earth’s health. In his article, “Boundaries for a Healthy Planet,” he argues that while climate change gets ample attention, species loss and nitrogen pollution exceed safe limits by greater degrees. In addition, other environmental processes such as ocean acidification and stratospheric ozone depletion are also moving toward dangerous thresholds.

This is the second installment of the Institute on the Environment’s Big Question series. The first video – titled “Feast or Famine?” – can be viewed here: http://www.youtube.com/watch?v=F1IWkbU0SG4
But just to show I am Fair and Balanced(tm), here is the other side of that debate:
