Welcome to my school!
We should use less energy, so what should we do? We should think about recycling everything. We shouldn't throw bottles or cans away. We should turn off the lights when we leave the classroom. We should use both sides of writing paper and we should turn off faucets when we leave the toilet. At the same time we shouldn't waste water and electricity. We should turn down the heat. So nothing is more important than saving our environment. We must do it!
