Greta Thunberg: Speech to world leaders at UN Climate Action Summit

Greta Thunberg gained support all around the world after she started a movement encouraging young people to help her raise awareness about the impact of climate change. At the beginning of 2020 Greta came to the UK and joined in with protests in Bristol; then of course the world went into lockdown. Her Fridays for Future strikes have now returned (as of last week) to demand that world leaders take action on important climate issues.
