23、Possible version:

The pictures above show us a commonly-seen phenomenon around us in everyday life.

There lies a bag of rubbish on the stairs of an apartment. Well-dressed Mr. Brown passes by the rubbish without any intention of throwing it into the dustbin because it’s that dirty; Ms. Turner does the same as she thinks to herself “What a mess!” While the bag of rubbish is left untreated, little Bob comes happily, picks up the bag and throws it into the dustbin, leaving those two ashamed by their own behavior.

As everyone knows, making a better world needs our contributions. However, to some of us, saying is one thing while doing is another. Complaining doesn’t make any sense. Just like Bob, we’d better not spit in public or throw rubbish around. We should keep off the grass and plant more trees to keep the air clean. Since we are members of the big family of the world, why don’t we do every little thing good to the environment?
