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 2Natural Resources
Through the changes in the ways of making a living in a family over several generations, the cartoon aims at sounding a warning against man's wasteful use of natural resources and emphasizing the urgent need to preserve these resources.
Ever since man appeared on the earth, man’s survival has been heavily dependent on nature. Almost everything we use in our everyday life comes from nature, ranging from the food we eat, the water we drink, to the wood which is turned into furniture. With the development of technology and population growth, the amount and range of materials used has increased at an alarming rate.
However, natural resources are not inexhaustible. Some reserves are already on the brink of exhaustion and there is no hope of replacing them. The widespread water shortage is an example in point. If man continued to squander natural resources with no thought for the future, the whole world would be in a mess. (157 words)
