Something we teachers have to do is to teach our students to take care of the environment, this is, to be environmental-friends.
One example is when leading them along an excursion not to let them drop any wrapping plastics or cans.
These lessons usually get stuck into their minds, and they could turn into a positive habit. Someone said: to give an idea and you will receive an action, to make them do an action and you will receive a habit, to give them a habit and you will receive a virtue and a value. / Photo from: planting tree www doyourpart com
