To save the Earth

The farmers ... stop using chemical fertilisers in the fields, that leads to pollution and exhaustion of soil.

The authorities ... ban cars in big city centres.

Plants and factories ... be provided with high technology equipment to reduce harmful emissions into the atmosphere.

Logging companies ... have cut down so many trees and destroy forests.

We ... travel by bikes or public transport than drive private cars in cities.

One ... throw plastic bags and bottles in the sea or ocean, that brings death to fish and animals.
