Saving the Environment: One Home at a Time

Pollution can be seen not only throughout the world, but also in our own homes. It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things.

First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.

Second, we need to watch the amount of water used at home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth.

Third, we need to reduce waste. We need to recycle whenever possible, but should also try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing.

If we do our part in our own homes, we can help keep the planet from becoming more polluted.

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.
