In discussions like this, people often drive by each other talking about different things. Most people don't know what capitalism is, or what socialism is, and argue with ideas that don't fit each other's ideas of what's being discussed. There are people who think capitalism and socialism were around 1000 years ago. Neither is true, or possible.
Nor is it possible to look at how societies have developed over recent history on a fish forum. By recent, I'd start in the 1600s... It's complex stuff that too easily becomes labels flying around rather than serious discussion.
The tragedy happening in Amazonia is driven by a lot of human social forces, with a primary one being market forces. There's also population expansion, ideology and greed. Some think that's great, some don't, but none of us hold any power in the debate.
You're a good bunch of people, but we live in a time where some countries are crippled by labels and polarization. There's no use spreading that around when we sought out this place to discuss fishkeeping. The article linked to is horrifying, and those who bother to read it should be shaking their heads. If we want to make or support changes, we aren't going to manage that on a fish forum. The solutions ARE politics. I'm all in favour of people getting involved there. But here, I don't want to know your approaches. They don't matter here.
