@tavelarocque: Day 90 of the @HigherUpWellness speak your mind challenge. a man trying to make the world safer poisoned more of the planet than anyone who ever lived. thomas midgley was one of the most celebrated inventors of his time. engines were destroying themselves, so he found an additive that fixed it instantly: lead. he swore it was safe, he once washed his hands in leaded gasoline and inhaled the fumes in front of reporters to prove it. then refrigerators needed a safer gas, so he invented one: cfcs. he was hailed as a hero of progress, twice. and here's what nobody saw coming. the leaded gasoline poisoned the air of the whole planet for generations and lowered the intelligence of hundreds of millions of children. the cfcs floated up and tore a hole in the ozone layer. one historian said midgley had more impact on the atmosphere than any single organism in the history of the earth. good intentions don't make a thing safe. what you build is measured by what it does, not just what you meant to. #History #unintendedconsequences #Science #thomasmidgley #fail
