What we can we do to save the Earth?
we can save the earth by reducing, reusing and recycling. we should all use eco-friendly cars and recycle plastic bottles, paper and cans. We should save energy by switching off the lights when we leave the room and use energy saving bulbs. We can also use the fan instead of the air-conditioner.
