W: By saving water,
M: Well, how can we do that?
W: By not using too much water when we wash dishes, take a bath, and when we do other things like watering the plants outside.
M: Oh, what else?
W: When drinking or eating something outside, you should keep the garbage until you rind a garbage can to put it in. Because throwing rubbish carelessly makes our planet dirty, Do you like seeing rubbish all over the ground?
M: No, I don't. Do you have any other suggestions?
W: Yes, we shouldn't waste paper, because trees are being cut down to make paper. By saving paper, we save the forests where animals live.
M: So how can children save paper? I mean everyday.
W: Well, for example, when I was in kindergarten, I used to save newspapers so that I could fold things out of them like paper trees instead of just throwing them away. Now the children in our neighborhood collect newspapers once a month to take them to a factory as raw material.
