There are ways you can help cut greenhouse gases and help stop global warming.
They are simple things, but can make a difference if everyone does them!
Recycle glass bottles, jars, newspapers and magazines and tin cans. Save them and take them to local recycling centres.
Re-use plastic shopping bags and envelopes, don't get new ones.
Persuade your mum or dad (or whoever does the gardening) to have a compost heap.
Put a brick in a plastic bag into your toilet cistern, then the toilet will use less water each time you flush.
Use paper on both sides.
Try to buy products that don't use much packaging.
Give unwanted gifts and clothes to a charity shop.
Only fill the kettle up with the amount of water you need to boil that time.
Don't leave the TV or video on standby.
If you get lift to school in a car, take your mates along for the ride.
Ask whoever does your washing to use the machine at 40 degrees - this helps conserve power.
