答案
Let's take action and avoid waste
Nowadays we find waste in our school. Some students waste food when they have lunch or dinner. Lights are not turned off when there is no one in the classrooms. Water taps are found running.
As we all know that there are still many people suffering from hunger all over the world. Coal is used to produce electricity. It brings pollution, too. We will use up all our natural resource one day.
We must take action to reduce those kinds of waste at once to save our world. Only when everybody realize the importance and take action will we live a good life.
