LONDON, 20 SEPTEMBER - "Changing government policies to preserve the future". Thus the Labor leader Jeremy Corbyn addressing a crowd of 100,000 people in Westminster, in the largest British gathering of the world climate mobilization day. The 70-year-old Corbyn evoked a green turn because "destroying nature means destroying all of us" and he gathered the ovation of many young people present when he exalted the generational commitment and when he attacked the presidents of USA and Brazil, Donald Trump and Jair Bolsonaro.
