Helping the environment isn't just for grown-ups. We can all help and there are loads of easy ways that we can do our bit.

How many of your toys have batteries in them? For most children it's lots! Batteries have chemicals such as mercury in them, and when they're put into landfill rubbish dumps the chemicals often leak out and can eventually end up in our water.

The next time you need new batteries, ask your parents to buy re-chargeable ones. They come with a re-charger unit which you plug into an electricity socket for about eight hours, and then your batteries are as good as new. They cost a bit more than normal batteries, but they'll last you around 1000 times as long!
