Public good tokens aren't meant to be ownership rights to that public good. Instead of tokenizing the Amazon (the rainforest), you'd tokenize an outcome, like the reforestation of the Amazon. If done right, the valuation of that token becomes how much that public good is valued.
An overly simplistic way of doing that for the Amazon is to issue 100 tokens every year and distribute them to people that planted trees in the Amazon. If someone plants 20% of all new trees this year, they get 20 tokens.
I'm ignoring a lot of challenges like making sure these trees are actually planted, and that they'll survive, and that these planters aren't the same people destroying other trees. But if you address these challenges then you have a token whose supply growth is limited and that allows investors to create a market for people to compete with each other to plant the most trees in the Amazon.
At the very least, it's a much better way of investing in Amazon reforestation than a donation, and I'm sure many millions are donated for this every year. But more important you're creating a store of value token whose value is backed by its ability to create a public good - value that's never been stored before. If you scale that up, you're creating a lot of wealth and you're changing human behavior.
