Teenage climate activist Greta Thunberg has once again hit out at world leaders, accusing them of 'silencing' the youth. Addressing a climate rally in Madrid, Thunberg said, "people want everything to continue like now and they are afraid of change". Thunberg also added that calls for real action against climate change are still being "ignored" by political leaders. Thunberg is in Madrid while the United Nations-sponsored talks on climate change is underway. The march was led by dozens of representatives of Latin America's indigenous peoples and organisers claimed 500,000 people showed up for the march.
