1 – John Muir

John Muir’s birthday is today. This is the first of three days corresponding to the three phases of the environmental movement.

Muir is the arch-activist for this “conservation” phase. “Saving” Yosemite is the arch-typical action.

The three phases, with their arch-activists are:

  1. Conservation, John Muir (birthday April 21), starting around 1890
  2. Pollution, Rachel Carson (Earth Day April 22), starting around 1970
  3. Climate Change, Bill McKibben (April 23), starting around 2005

Rachel Carson and Bill McKibben were, like Elizabeth Kolbert, who just won a Pulitzer Prize for The Sixth Extinction, writers for the New Yorker whose activism expanded beyond writing.
