Passage 48
Population Growth
It is well-known that there has been a drastic increase in world population. But it is probably less well-known that the extinction rate of wildlife species is experiencing a parallel trend.
Take the United States for instance. In 1990, U.S. population reached an unprecedented level of 250 million, which is approximately 250 times of that of 1800. On the other hand, wildlife species are disappearing from the country at an alarming rate. By 1900, about 70 wildlife species would never be seen in U.S.. We are fully justified in declaring that the explosive population growth has had an adverse effect on the survival of wildlife species and will be a constant threat to the wildlife resources if no immediate actions are taken.
Nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world. It has been demolishing the environment we are living in.

Passage 25
A Place of Our Own
We are all usually very careful when we buy something for the house. Why? Because we have to live with it for a long time. We paint a room to make it brighter, so we choose the colours carefully.
We buy new curtains in order to match the newly decorated room, so they must be the right colour. We move the furniture round so as to make more space — or we buy new furniture — and so on. It is an endless business.
Rich or poor, we take time to furnish a room. Perhaps some people buy furniture in order to impress their friends. But most of us just want to enjoy our surroundings. We want to live as comfortably as we can afford to. We spend a large part of our lives at home. We want to make a small corner in the world which we can recognize as our own.
