Meghan Markle, who married into Britain's royal family in May, has focused on women's rights and collaborated with survivors of London's Grenfell Tower fire to create a community-led cookbook. She also wore "slave-free" jeans from Outland Denim in Australia, sparking a rush to purchase the trousers. 2. Emma Watson, best known for her role as Hermione in the Harry Potter films, supported the #MeToo movement in 2018 by donating one million pounds ($1.3 million) to a fund that helps charities fighting sexual abuse. In October, Watson penned a public letter calling for an end to restrictive abortion laws across countries like India and Ireland. During that time, she was also seen wearing earrings made from shrapnel and unexploded bombs from Laos. David Attenborough, the elderly nature documentary broadcaster, used the United Nations' climate talks in Poland in 2018 to join forces with young people and emphasize the urgent need for progress on climate action. Bollywood legend Amitabh Bachchan solidified his popularity in India by paying off the debts of farmers with over 40 million rupees ($560,000) following an agricultural crisis that had plunged many into extreme poverty. 5. Elton John, the British musician known for his support of LGBT+ rights, urged for increased efforts to help individuals in poverty access HIV/AIDS medical treatment, labeling the limited access as shameful.
