Before I retire from teaching, I wonder if I’ll be able to teach a course called “Lost Environments,” where I tell students about what were once coastal ecosystems that are now under water because of our headlong rush into climate change? I can show lots of pictures of the Everglades and Bangladesh and Louisiana and Pacific Islands. I can talk about all the extinctions that are taking place. Everyone can share stories of how their parents and grandparents homes are now underwater and how their drinking water is now saline. We can tour the multi-trillion dollar seawalls keeping New York dry, seawalls that will inevitably collapse and inundate America’s greatest city. Because this is the future.
