Amy Miller: “An interactive map that shows you where your town was in relation to landmasses and oceans millions of years ago has been making the rounds of social media this week. What begins as a fun diversion—‘My house was beachfront property in the Late Cretaceous!’—becomes an existential rabbit hole when you start reading the descriptions (lower left corner) of what was happening on the planet at that time. At many times, what was happening were mass extinctions. Pondering the massive die-offs and how many millions of years it took for life to rebound each time, and how often that has happened—it’s a staggering, sobering perspective. I probably learned this all in school, but I was young and it didn’t stick. It’s sticking now.” (web)
