So it can may have influence on a couple of thousands or some million people. Global warming has influence on all ecosystems. So in one or the other way on all human beings, animals and plants of this earth. It will inevitably cause mass migration the world did not have encountered yet. And the world will offer less opportunities for life in total. So I have no doubt, that the emission of carbon dioxide is the biggest cause of future wealth destruction. And the reduction of its emission can lower the most harm in the world. The total productivity of our world has its roots in the opportunities for life. When less life is possible, less wealth is possible. And no speach in the world and no oppinion will change a damn thing in this reality.
