Waste paper should of course be collected, but reducing waste paper is something that elementary school students can do. Using both sides of the paper is a way to save energy, and using less paper reduces the environmental pollution caused by papermaking.
On particularly hot and cold days, if the classroom has air conditioning and heating, close the windows and doors to reduce air circulation and maintain the temperature in the classroom, which can reduce energy consumption.
The use of water is also very important. If the water we use does not contain chemicals, it can be reused, for example, the water used to mop the floor in the classroom can be used to water flowers and trees. At home we use the water we use to wash dishes and bowls to flush the toilet, and the water we use to wash clothes to mop the floor and flush the toilet, which saves 40% of the water we use in the home.
And students should not waste food, which is a resource for human survival. The food you bring or eat in the school cafeteria should be eaten as much as possible, do not waste food is not a waste of resources.
Life is reflected in our daily activities, to maintain a good habit of life, saving habits, day after day will have obvious results.
