#Regram #RG @guardian: Young people striking from school over climate change have issued an open letter ahead of a global day of action on 15 March. Students across 50 countries are expected to participate and nearly 500 events are listed to take place on the day. Janine O’Keefe from FridaysForFuture.org hopes to see "over 100,000" participating in the day of action. The letter was written by a global coordination group of 150 students, including the first youth climate striker Greta Thunberg.
