Rubbish and recycling
Not clearing up litter or rubbish can be harmful to the environment. Broken glass can be stepped on, plastic is a choking hazard to animals. Leave litter lying around can damage in the environment in which wild animals live in and pollute our seas.
Plastic, paper, glass, metal, food, garden waste can all be recycled. Recycling this waste can save it going into landfill sites and being buried in the ground. It takes a long time for our rubbish to rot in the ground. A plastic bag takes 10-20 years, nappies take 450 years and a glass bottle takes a whopping 1 million years!
See how long it takes for our rubbish to rot.

We can all make a difference to our planet and reduce the number of greenhouse gases we put in our atmosphere by saving energy around the home.
- Turn lights off when you have left a room. Turn all electrical devices off when you have finished with them. This includes TV's, computers, game consoles. Putting them on standby still uses electricity.
- Turn the thermostat down. This controls how warm your house gets. By turning it down by 10 degrees can make all the difference.
- Shut the fridge and freezer door. Every time you open the door one-third of the cold air escapes and it takes more energy to cool the appliance down again.
- Change your light bulbs. You can now get energy efficient light bulbs that use less electricity.
- Take showers instead of baths. They use less water which means you will not only save energy in heating less water you will also save water too.
- Turn the tap off while brushing teeth. Only turn on the the tap when you need it.
