We found an interesting and strong fact that the carbon emission of a person's excrement is also very high, only people don't notice it, and at the same time did you know that the carbon absorption of a tree in one year can almost offset the emission of a person's excrement in two years? We propose: a tree can absorb the carbon emissions from your urine, so you plant a tree from the ecological tree, you can pee without worrying, our idea is OWN A TREE & FREE TO PEE, invite the world's most famous pee boy at COP28 to draw attention and through a series of actions to get people to start planting a tree and then feel free to pee!
