Whale oil provided the lighting to read the breakthrough novel of 1870, the story of Captain Nemo in 20,000 Leagues Under The Sea. That was also the year of the foundation of Standard Oil. The result of that foundation is that we didn’t hunt the whales to extinction, but instead turned to kerosene to light the latter part of the 19th century, moving to electricity only in the 20th.
It really isn’t hyperbole to insist that John D. Rockefeller saved the whales by his making mineral oil products so much cheaper than the cetacean-derived equivalent. And that’s really all you need to know to understand Earth Day and what to do about it.
If you’re not a capitalist free-marketeer for Earth Day, then you’re not being serious about the environment, are you? And that would make Gaia sad and Mother Earth cry.
