Bob and Jessie are walking through the park. Bob is eating a piece of candy and he litters on the ground. Jessie believes that it is wrong and decides to stop him.

Bob, I saw you drop something on the ground.

OH, come on Jessie.It was just a little piece of plastic. it's not a big deal.

You might think that it isn't a big deal. But it is.

What do you mean?

It will hurt the environment and take away from the park's natural beauty.

Oh, come on, just one small piece.

But it's the rule. People shouldn't litter even a litter. It's not right.

Don't pick on me. I've seen lots of litter in some of the neighbourhoods around town.

So? Just because some people do so doesn't mean it's ok. Everyone should care about the environment and help protect it.

Hey, it's not like l dropped a big bag of rubbish on the ground.

You know we are in the park. If everyone who visited dropped one piece of rubbish, the public place would be dirty.

Well, maybe there should be more public rubbish bins around, it would be more convenient to throw things away.

Um, we are going to walk past a rubbish bin on our way home.

Remember? It's near the bus stop.

Oh, yeah! Well, let me pick it up and throw away.

Now, let's head home.
