I actually know this one!
There's a traditional coconut farming technique in Thailand where they send monkeys into the trees to pick the coconuts. This is like a traditional centuries old thing that doesn't hurt the monkeys at all. Since Thailand is in asia, animal rights groups have been focusing on it the last few years as some kind of issue even though if a monkey doesn't want to do something there's nothing you can really do to make it do that because it's a monkey.
Nonetheless racist "animal rights" groups go around discussing it as though it's slavery or a labour rights issue. Personally I think they're being paid by people who get coconuts some other way but I can't prove anything.
Anyway, it's basically MSG again in that it catches on because of anti-asian stereotyping and none of the allegations are true or really even make sense when you look at them. Animal labour in agriculture is really well-established. That's where we get the term "horsepower". Because horses were doing the. The power. But there are no monkeys in Europe so Europeans didn't do that so it's an evil rights issue.
We domesticate animals and use them for labour. Big if true.
