Read the text and make the sentence complete.

The most famous unusual animal is the panda. Twenty years ago it was nearly extinct. Now its numbers are growing again. But many other species have been less lucky than the panda. Sonics are already extinct. Today many more animals are in serious danger.This is because man hunts them, destroys and pollutes their habitat.

After pollution habitats take many years (sometimes hundreds or even thousands) to grow again.

Pollution changes the balance of nature. Each species in a habitat (for example, wood, jungle or forest) needs and helps the rest. If one animal, bird or insect disappears, all the others suffer, too.

This is what's happening in the rainforests of South America, Africa and Asia. These are some of the world's oldest habitats. Man is destroying an area of rainforests as big as Switzerland every year.

But the problem doesn't stop there. Habitats and animals are disappearing in Europe, too. And what has taken the place of these green, natural places? Houses, farms, cities, streets, roads and factories.

There is only one way to save wild animals and wild habitats - conservation. That means protecting animals in danger by law, opening more national parks, building fewer new roads, planting more new forests, cutting pollution. If this doesn't happen, many wild animals will soon have just one habitat - the Zoo.

Each species in a habitat ____________ the rest.

needs and helps

doesn't need
