Leonardo DiCaprio pens stirring message about climate change activist Greta Thunberg

Actor Leonardo DiCaprio has written a stirring Instagram about climate change activist Greta Thunberg being a "leader of our time". DiCaprio - well known for his environmental activism - posted on Saturday a long message praising the teen who sparked international protests calling for greater action in combating climate change.  "There are few times in human history where voices are amplified at such pivotal moments and in such transformational ways – but @GretaThunberg has become a leader of our time," he wrote alongside a picture of the pair together. He said "history will judge us" for the action we take in fighting global warming and environmental dangers, saying it was up to the current generation to safeguard the planet for others. Gretaberg also considerable attention for her fierce speech to politicians at the United Nations in September, calling them out for what she said was a lack of urgent environmental action. The actor said he hopes they listen. "I hope that Greta’s message is a wake-up call to world leaders everywhere that the time for inaction is over. It is because of Greta, and young activists everywhere that I am optimistic about what the future holds." He called it an honour to spend time with her and pledged to support the teenager in her journey to advance work against the threat of climate change. While DiCaprio has made environmental activism part of his brand - discussing climate change while accepting an Academy Award in 2016 - he has also been criticised for his use of private jets.
