Hello Friends
Hello friends,
I call you friends, my students, because we are standing on the same side today. We are a harmonious unity and I believe we can do something together, especially for the aggravating environment.
We are all living in the same surroundings, and have seen how it goes worse and worse. Don’t we feel sorry for it? I believe we do, for you are all my pretty children.
So, let’s begin to do it by doing little things. For example, not using plastic bags, for they really damage the environment a lot. Plastic bags will not disappear in the soil for hundreds of years. It’s of course one of the most dangerous enemies to environment, and let’s get rid of them.
I believe you can, and so do I.
