About one percent of all the rainforests in the world are lost every year. We know this because satellites give us true pictures of the rainforests. Satellite pictures tell us, for example, that between 1978 and 1988, 170,000 square kilometers of the rainforests in the Amazon were lost.

When roads are made through the rainforests, people start to destroy the forests. Look at the satellite picture taken in 1976.You can see the new road going through the rainforest. The second picture shows the same forest in 1981.The rainforest in this part of Brazil has been destroyed very quickly.

Without the trees to protect the ground, the heavy rain quickly washes away the soil beside the roads.

The rainforests are rich in trees and animals, but the soil is not rich; it is very poor because it is very old and because the trees and plants contain all the good things that were once in the soil. Without the trees, the rain washes away the soil and nothing can grow there again.

Look at the picture of Madagascar. Thousands of trees once covered these mountains, and thousands of animals lived there. Nothing can grow there now, and no animals can live there.

Are we going to destroy all the rainforests of the world? Perhaps one day you will travel to a rainforest country, but will you see the wonderful plants and animals of the rainforests?

Traveling by train is usually not easy in China. It can be hard to get a ticket. When you’re traveling to the railway station, you look at your watch, for you are afraid you will miss your train.

But there is good news for people traveling between Beijing and Shanghai. Construction (建设) on the express railway (高速铁路) between the two cities started just before the Spring Festival of 2008. When it is finished by 2013, taking a train will be as easy as taking a bus.

“There will be trains every several minutes. Buying a ticket, getting through the checkpoint (检查站) and taking your seat, will take just 10 minutes,” said an engineer.

There may be high-speed trains running at 350 kilometers an hour. The travel time between the two cities will decrease from 10 to about 5 hours. The trains will carry twice the present number of passengers.

The new line will be 1,318 kilometers long and go across specially built bridges. It will run along side the present line. There will be 21 stations in Hebei, Tianjin, Shandong, Anhui and Jiangsu.

“The cost of traveling by the express railway may be around 800 yuan. That will be more expensive than an ordinary train, but cheaper than by air.” Said Zhang Xiaoling, a Jiangsu government official.

According to Zhang, the higher price is caused by the large cost of the railway project. At about 200 billion yuan, the project may be even more expensive than the Three Gorges Project (三峡工程).

Is the world too crowded? Well, that’s a hard question to answer. It’s all a matter of perspective(视角).In Montana, you might drive for a mile in any direction and not see another human being. In Macao, 60,000 people live in every square mile!
What is true is that the world’s population doesn’t stay the same. It has been increasing at a very fast rate(比例).That’s in part because in each generation(代) these are more people who then have children than in the last generation.
Five hundred years ago, the population of the world was about 460 million. In 1900,the world’s population was under 2 billion(十亿).Right now it is doubling every 40 years. That means, if this rate of growth continues, when you are a parent, there will be twice as many people on earth as there are now. Wow! Now that’s a whole lot of people! Soon the world’s population will probably reach 7 billion. Some people worry about that! But there is a lot of disagreement about just how many people on earth equals(相当于) too many people. But everyone agrees that the more people there are, the more resources(资源) the world needs to feed, house and take care of all of them, and the more need there is to think carefully about how we live and use the earth’s resources.
