Earlier quoted context omitted.
Kinda like how whale oil was displaced by dug up hydrocarbons.
Whaling was still happily going until there was an international ban in the seventies or eighties. Despite hydrocarbons whale oil and other products were still used in a surprising range of things. Even now after the "ban" that catch is pushing up near 10,000 a year.
Not sure this is true. This site[0] puts the total 2018 catch at only 1553.
