Please read all of 15-year old Greta Thunberg's speech at the U.N. climate summit in Katowice, Poland.
I school-striked for the climate. Some people say that I should be in school instead. Some people say that I should study to become a climate scientist so that I can “solve” the climate crisis. But the climate crisis has already been solved. We already have all the facts and solutions. And why should I be studying for a future that soon may be no more, when no one is doing anything to save that future? And what is the point of learning facts when the most important facts clearly means nothing to our society?
Today we use 100 million barrels of oil every single day. There are no politics to change that. There are no rules to keep that oil in the ground. So we can no longer save the world by playing by the rules, because the rules have to be changed.
And since our leaders are behaving like children, we will have to take the responsibility they should have taken long ago. [emphasis mine]
