What do you know about Earth Hour
Started in 2007 by WWF and partners as a symbolic lights-out event in Sydney to raise awareness of climate change, Earth Hour is now one of the world's largest grassroots movements for the environment. Held every year on the last Saturday of March, Earth Hour engages supporters in more than 190 countries and territories, all taking action to ensure a brighter future for people and the planet. Earth Hour has also gone far beyond the symbolic action of switching off - it has become a catalyst for positive environmental impact, driving major legislative changes by harnessing the power of the people and collective action.
Earth Hour started in 2007 in Sydney, Australia.
In that year, 2.2 million people turned their
lights off for one hour. They did this to show
that they cared about climate change. Since then, people from all over the world do the same on the last Saturday of March every year. More and more countries are joining Earth Hour.

参考答案
预习案
Earth Hour was a moment of solidarity, where people from 192 countries and territories came together in support of people and our planet. We saw landmarks turn off their lights and supporters switch off at home, as well as a range of activities such as virtual concerts, mangrove planting, street clean-ups and virtual runs.
Public figures and celebrities, such as UN Secretary-General António Guterres, Justin Trudeau, Ellie Goulding, Iwan Rheon, Claudia Bahamón, Gianella Neyra, Mr Leo, Ben Pol, Liu Wen, Dilraba Dilmurat, Shruti Haasan and many more, also showed their support. Earth Hour showed that we can all play a part to shape a safer, fairer and more sustainable future for everyone on our planet, the one home we all share.
