мн твр Opinions about saving the Earth

Our planet is in big trouble - creatures are dying out, the sea and the air are filthy, more and more airports, cities and roads are covering our land and we only have ourselves to blame.
1 Recycle, recycle, recycle! Dont throw away plastic bottles, glas jars, newspapers, cardboard boxes and cans. They can all be used again.
2 Use public transport instead of the cars.  Or why not walk or cycle to school or work? Its free, good exercise and doesnt harm the environment at all!
3 Take showers instead of baths and use less water when you wash dishes or wash the car or water the plants. Dont waste electricity either. Switch lights off when you leave a room and use low-energy bulbs.
