Last week our class had a heated discussion on Earth Hour．Different students have different opinions about this activity．
About 60% of the students are in favor of it． As we all know ,global warming is a big problem in the world． Earth Hour can raise people’s awareness of global warming． Besides, turning off lights for an hour is energy-saving． Only by working together can we make our earth a better place to live in．
However , about 40% of the students say this activity is not very meaningful． They think it is only a show and that it doesn’t make much difference． What’s more, turning off lights for an hour may cause inconvenience to people’s life, work and study．
In my opinion, this activity is of great importance． But one activity alone is not enough if we want to save energy and protect our earth． Let’s act through our day-to-day habits.
