1)b) Introduction

We all want to reduce our impact on the environment. What can we do to make a difference? Here

arc some ideas which everyone can try:

(2)c) Reusing rubbish

We throw away a lot of items which we can use again. Did you know that recycling one tin can

save enough energy to power a television for three hours?

a) Reducing food waste

• We throw away a third of everything we buy at the supermarket. But at least half of the items

which we throw away are still fresh and tasty

d) Fewer plastic bags and containers

• Buy things which don't have much packaging. Govemments are trying to make supermarkets

reduce their use of packaging, but progress is slow.

e) Cleaning up your area

• Rubbish in the streets looks horrible, but it is also an environmental problem. Rubbish can pollute

the water we drink and the ground we grow plants in

(6)g) Environmentally-friendly travel

• Cars, motorcycles and planes all cause a lot of pollution. Try to walk or cycle. If your journey is

longer, use public transport, such as buses or trains.

If we all act now, we can make a difference!
