There are a few reasons for it, I would guess. From conservation being much more mainstream in japan, japan typically being more community-oriented than individualistic, or simply because, for whatever reason, the average piece of Japanese media tends to be significantly more blunt about its messages and themes than the average piece of western media.CoCage said:Minor side rant, but what is up with Japanese media (Americans sometimes too) with the whole badly done Humans Are Bastards or the "Real Monsters". Most of the time it's ham-fisted, barely makes sense, and the writer(s) either come off as misanthropic or delusional acting like they're making high quality art. If anything speaks more about them than any of the problems with humanity society. It's like they have something to say, but in reality the writers don't and come off as know-nothing-know-it-all, petty, try-hard teenagers shouting everyone sucks and here is why.
That said, there are a few anime I've encountered that manage to have green messages and still manage to raise interesting points or complex discussions on the topic. If you ever find yourself lacking something to watch, give "Parasyte: The maxim" a watch. When the series gets to the point where characters ponder the origins of the titular parasitic creatures, it starts to look like the series is winding up for a great big "HUMANS ARE THE REAL MONSTERS" message, but then at the last minute it reveals a message that's actually quite a bit more nuanced and mature, that protecting the world is important, yes, but it's not evil to prioritize protecting the things you care about, and that all aspects of human nature are born from the same drives that inhabit all earth's creatures. Thus one cannot claim to love the earth if in the same breath they espouse hatred of humans, for humans are as much a child of the earth as any other.
I was pleasantly surprised. criminally underrated show
