Most Popular Articles of November: Fracking Causes Earthquakes, Lt. John Pike's Pepper Spraying Revolution, and More

We also have the photo of Lt John Pike pepper spraying UC Davis students, a roller coaster turned into a promenade, a surfer nearly swallowed by a humpback whale, and more in our roundup of the most popular stories on TreeHugger this month.
