Vote for 15.2 --- I would agree with YingChu here with 15.2 being the most important for two reasons: 1. that CO2 emissions are the most contributor to greenhouse gases and the most dangerous and those having the most impact in what we call today climate change. The first way to tackle CO2 is by keeping Oxygen engines in and have more if we can 2. Deforestation is an absolute ignored challenge by leaders for its industrial benefits, greed is blocking the scene being clear about the impact of it on the future generations
