Task 1rnI'm a big fan of saving the environment, and I take part in Earth Hour annually. Earth Hour is an event where you turn off all unimportant lights and power between 8:30 pm and 9:30 pm.rn1 Instead, people gather in groups and have fun without using power. Things like dancing and musical performances are popular and it's very fun to take part.rnI have taken part in Earth Hour for years. Last year, for example, my university had an outdoor cycle cinema. At the cycle cinema, the only way to keep watching the film is to keep riding your bike. If everyone stops, the screen turns off. 2 Everyone who was there had a lot of fun.
