At some point you've just got to decide for yourself. A lot of focus on human lives and especially qualys because they can be thought of as interchangeable but that hasn't stopped some EAs from focusing on animal welfare and other non humanist causes. There's no objective way to value rainforest or animal suffering in terms of qualys, all you can do is thought experiments and read studies on effectiveness of charities focusing on each so that you can decide which is more effective given your ethical framework.
