Read the following passage and fill in each numbered blank with ONE suitable word.

                                                   SAVE THE WORLD

Every ten minutes, one kind (29)………….animal, plant or insect dies out forever. If nothing is done about it, one million species that are alive today will have become extinct twenty years from now.

The seas are in danger. They are being filled (30)………….poison, industrial and nuclear waste, chemical fertilizers and pesticides, sewage. The Mediterranean is already nearly dead. The North sea (31)………….following. If nothing is done about it, one day soon nothing will be able to live in the seas.

The tropical rain forests, (32)………….are the home of half the earth’s living things including many rare animals and plants, are being destroyed. If nothing is done about it, they will have disappeared in twenty years. The effect on the world’s climate and on our agriculture and food supplies, will be disastrous.

Fortunately, somebody is (33)………….to do something about it. In 1961, the World Wildlife Fund was founded – a small group of people who wanted to (34)………….money to save animals and plants (35)………….extinction.

Today, the World Wildlife Fund is a large international organization. It has raised over 35 million dollars for conservation projects, and has created or given support to National Parks in five continents. It helped 30 mammals and birds, including the tigers, to survive. Perhaps this is not much, (36)………….it is a start. If more people give more money – and if more governments wake up to what is happening – perhaps the World Wildlife Fund will be able to help us to avoid the disaster that threatens the natural world, and all of us will be with it.
