Well I have just listened to the most stunning essay by Greta (remember she is 16 years of age) about what she has been doing, how the world reacts to her, what the USA is like, how much ignorance there is, how what needs to happen cannot happen with the systems we have in place and yet there is still hope through movements like "me too", black lives matter", the school strikes. Please listen to this astonishingly needed piece of journalism
