Part 1
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 spedes is altering the physical and chemical world. It has been demolishing the environment we are living in. (152 words)

Part 2
House and Home
"House" and "home" are two words that have similar meanings.
"House" and "home" both refer to places where people live. However, there is a difference between them. "Home" is often referred to as the place that we live in with our families. Sadly, in our society, people can hardly distinguish a home from a house because they often see no difference between them. This confusion can be traced back to the indifference between family members. Therefore, we can say that love is an important factor in a home. A home is a shelter, not only for our bodies but also for our minds. Whenever we are depressed, we can go home for comfort.
Everyone in the family will do his best to take care of each other and share their happiness as well as sorrow. Without love, a home is merely a house where loneliness is all that can be found. And a house can never be a home unless there is love. (163 words)
