I am particularly sad that no one knew how to stop climate change during the 1930s. CO2 was very safe during the Dust Bowl.

“And then the dispossessed were drawn west- from Kansas, Oklahoma, Texas, New Mexico; from Nevada and Arkansas, families, tribes, dusted out, tractored out. Car-loads, caravans, homeless and hungry; twenty thousand and fifty thousand and a hundred thousand and two hundred thousand. They streamed over the mountains, hungry and restless – restless as ants, scurrying to find work to do – to lift, to push, to pull, to pick, to cut – anything, any burden to bear, for food. The kids are hungry. We got no place to live. Like ants scurrying for work, for food, and most of all for land.”

– John Steinbeck, The Grapes of Wrath, 1939
