The world cuts down more than a million trees every year to make paper and paper products.

In the USA, each person uses about 300 kilograms of paper each year. In Europe, the figure is 200 kilograms. In India, each person uses only 6 kilograms of paper each year.

It takes two tonnes of wood and 200,000 litres of water to make a tonne of paper. About 30% of our rubbish is paper and paper products. It is wasteful to dump them. Paper on rubbish dumps doesn't do anybody any good. It decays and produces poisonous gases, it is better to collect waste paper and other paper products and recycle them. Recycled paper produces 35% less water pollution and 74% less air pollution, and uses 48% less energy and 58% less water than new paper.

Toilet paper, egg boxes and paper bags are good examples of possible recycled paper products.
