MUMMY, OH MUMMY

"Mummy, oh Mummy, what’s going to happen

If all the pollution goes on?”

"Well, the world will end up like a second-hand junk-yard,

With all of its treasures quite gone.

The fields will be littered with plastics and tins,

The streams will be covered with foam.

Now throw those soda bottles over the hedge,

Save us from taking them home.”

“But Mummy, oh Mummy, if I throw the bottles,

Won’t that be polluting the woods?”

“Nonsense! That isn’t the same thing at all,

You just keep quiet and be good.

If you’re going to start getting silly ideas,

I’ll take you home right away.

Because pollution is something that other folks do,

We’re just enjoying our day.”
