From the demonstrations in all the great cities of the world to the confrontation to the UN between the activists and the leaders of the youth movements ready to make commitments on the field. The day after the Climate Strike, the global youth protest for the environmental emergency that brought 4 million children to the streets in 163 countries on Friday, is concentrated in the hall of the United Nations Youth Climate Summit. A meeting called for by the general secretary Antonio Guterres to push young people to follow up on the protests and make world leaders feel that tomorrow at the glass building they will discuss the implementation of the Paris climate pact, the breath on the young generations' necks.
