The Great Lakes are Stressed

• Aquatic habitat alterations: Changes to aquatic habitat from diverse causes, such as shoreline hardening and erosion control structures, port and marina development, and tributary dams
• Climate change: Changes to seasonal, average, and extreme temperature, precipitation, and ice cover
• Coastal development: Land-based human development near lake margins, such as residential and commercial development and industrial activities
• Fisheries management: Changes to Great Lakes ecosystems resulting from fishing pressure, stocking activities, and aquaculture
• Invasive species: Changes to Great Lakes ecosystems from invasive and nuisance species in abundances not previously seen
• Nonpoint source pollution: Nutrients, sediments, and waterborne contaminants transported from watersheds to the Great Lakes by streams and rivers and atmospheric deposition
• Toxic chemical pollution: Chemical pollutants from industrial and agricultural sources

West Michigan Beach in Winter

Pictured is a snow fence to keep sand and snow from blowing across the road.  Fierce winter winds whip the snow and snow plows try to keep up with clearing the roads.  There is so much snow today that school was cancelled in many areas of West Michigan.

Read about weather and the Great Lakes in my book, The Dynamic Great Lakes.   Available at bn.com, Amazon.com, Amazon's Kindle reader and many fine bookstores.

Swan

I have seen swans around Lake Michigan.  They are quite lovely to see but quite feisty when approached.
