Why do plants grow in some places and not in others Why does some land have so many plants growing on it, while other land has almost no plants growing on it at all
To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the earth only a few unusual plants can grow. That’s why dry deserts are almost not covered with trees or grass.
Plants must also have a place to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land.
Another thing plants must have before they can grow is food.
What will happen if we try to make things grow on the sandy beach A few plants, such as
beach grass, will grow in sand, but most plants won’t. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.

All over the world, thousands of animals are used for wildlife tourism. People travel to watch monkey shows, hug baby tigers and swim with dolphins. It might look like fun, but there are reports that animals are hurt now and again. The World Animal Protection (WAP) says that up to 550,000 wild animals are exposed (暴露) to ill treatment around the world; in Cambodia, for example, it’s been reported that elephants have died after carrying tourists for long in hot weather. This is getting attention—over 100 travel companies have promised that they will no longer open up such places. However, some people argue that animal tourism isn’t always as bad as it seems. So what do you think
Group Yes
Animals weren’t put on this planet for enjoyment. They should be free to live as they choose.
The way animals are treated is often cruel and causes much pain. Even if treated well, they cannot act in the same way as they would in the wild.
We don’t need wildlife tourism. We can see animals close up in their natural home in TV programs. There’s no need to disturb(打扰) them in real life.
Group No
It is enjoyable and educational for people to communicate with the wonderful animals. The more people know about them, the more they want to protect them.
Wildlife tourism brings money to poor areas and may be the only way for some people to make a living.
Not all animals are treated badly. Some endangered animals are under the protection of programs that look after rare species (稀有物种).
