By changing our buying habits, we can help the environment. Plastic bags, polystyrene packaging, plastic film are made from oil which will run out. Half of the plastics are packaging and are thrown straight away. They can remain in the environment for hundreds of years without biodegrading.
Avoid foods that have lots of different packaging
Use your own lunch box, rather than pre-packed food
Avoid buying individually wrapped mini portions
Avoid using disposable bags or use bags which are biodegradable
