Humans have much in common with to other live forms on Earth. Since the very a first live form appeard, all living things have been desperately struggling to survive the harsh and changing conditions of our planet. This has involved adapting to new situations and in many cases has led to either evolution or the extinction. We are not alone in making use of the world around us (birds use twings to build up nests, for another example) or in being particularly skillful (spiders make intricate webs). Where we do differ from other life forms; however, it is in our ability to record and learn from our collective history. In this, it appears that we are unique. There is still too much mankind does not know about the earliest humans, of course not, but we are increasingly becoming a species with detailed knowledge that about our past. The more we learn from, the betterare our chances of survival in the future. It must also me recognized; however, that we are also the only species on Earth in which has managed to createthe mean of destroy the planet we live on.

Since the world has become ............ (industry),there has been an increase in the number of animal species that have either become extinct or have neared extinction. Bengal tiger, for instance, which once roamed the jungles in vast number, now only about 2,300 and by the year 2025, their population is ............ (estimate)to be down to zero. What is alarming about the case of the Bengal tiger is that this ............ (extinct) will have been caused almost entirely by poachers who according to some sources, are not interested in material gain but in ...........(p gratification. This is an example of the callousness that is part of what is causing the problem of extinction. Animals like Bengal tigers as well as other endangered species are a valuable part of the world's ecosystem. .................(nation) laws protecting these animals must be enacted to ensure their .......(survive) and the survival of our planet.
Countries around the world have begun to deal with the problem in ..........(vary) ways. Some countries, in order to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission to help defray the costs of maintaining the parks and they often must also depend on world organizations for support. With the money they get, they can invest in equipment, and patrols to protect the animals. Another solution that is an attempt to stem the tide of animal extinction is an international boycott of products made from endangered species. This seems fairly effective but it will not, by itself, prevent animals from being hunted and killed.

Unlike buried treasure and some minerals, fossils are usually not valuable in themselves. However, most of the fossils you find will be of greatest value to you. They will help you learn much about the geologic history of the earth and its inhabitants.

Unlike buried treasure and some minerals, fossils are usually not valuable in themselves. However, most of the fossils you find will be of greatest value to you. They will help you learn much about the geologic history of the earth and its inhabitants.

If it were not for fossils, we would have no way of knowing about the animals that once roamed the earth or that once crawled on the bottom of the ancient seas. In fact, we would not even know for sure that there were once seas in some regions if it were not for the many fossils of sea animals that we find there.

You can look at some fossils and see for yourself the shape of the ancient animals. Even if you collect only bits of one kind of fossil, you may still be able to tell what it looked like. Making sense out of fossil bits is a little like working a jigsaw puzzle. Sometimes you will lose pieces, but you can still recognize the picture and even use your imagination to fill in missing details. The habits of ancient sea animals are not so easy to determine. Therefore, scientists study the structure and the habits of similar living animals to learn what the ancient ones must have been like. There are some things, however, that neither the study of fossils nor the study of living animals can tell us. For example, no one knows what colour most ancient sea animals were. Also, since the soft parts disappeared soon after death, many details of their internal structure are unknown. So the pictures of ancient sea creatures (as well as dinosaurs!) are what scientists think the animals looked like. Reconstructing the life of an ancient sea animal on the basis of fossil evidence and the characteristics of similar living animals is a little like relying on circumstantial evidence in court.
