In the debates about how a particular piece of land is to be used, the priorities often conflict. What should you do, for example, if you find out that under the fertile fields of a farming community there is a thick bed of coal which can be strip mined(露天矿) ? Strip mining tears up top soil and plants. But mining may create jobs, bring money to the towns businesses. Those who approve of strip mining say that the coal is needed, and they point out that it is quicker and cheaper to get coal from the surface than to go deep into the earth to get it by standard mining techniques. On the other hand, it takes nature 500 years to create an inch of top soil. As the countryside fills up, people are becoming more aware of the need for open space. Nearly every proposal for a new power plant, highway, or airport draws fierce opposition. Everyone wants the big, land-eating “uglies” to be in someone else’s backyard. Minneapolis and St.Paul, Minnesota, for example, have been debating about the site of a future airport for years. Yet if a new airport is needed, it will have to go somewhere.
How do we find our way out of the land-used problem? One way might be to reexamine our values, to think in new directions. Does everyone have to have a car with its need for highways and parking lots? What about developing mass transport systems that use less land? Do suburbs have to spread? Can they be designed so they use less space? Do we have to have more energy? If we do, do we really have to strip-mine coal to provide it?
However difficult they may be to arrive at, choices will have to be made if we want to preserve the beauty and usefulness of the land. For there is at least one point on which all of us can agree: The land does have its limits.

You’ve bought what you need. The grocery cashier asks, “Will that be paper or plastic? You reply “Plastic, please.”
This seems like a simple question and there are plenty of reasons we choose plastic: easier to carry, lighter than paper bags, possibly less damaging to the environment, less expensive to the shop owners, able to be used as trash bag, and so on. There are different opinions on plastic and paper. Now let’s follow the travels of 3 plastic bags. It begins at the grocery store with the customer’s choice.
Plastic Bag 1: As the waste engineer come by and pick up the trash, the first plastic bag falls out. It sits on a small street for a couple of hours until a car comes along and takes it down to the road. Then a gust of wind blows it across the road, then another car, then another gust of wind finally makes its way to the beach. Water fills the plastic bag and makes it look like a jellyfish. A seal(海豹) swims by, thinking it looks very interesting, and swallowed it. The plastic bag may stay in the seal’s stomach for months, maybe years. You see, our lovely animals have been living thousands of years in a world where everything can be eaten.
Plastic Bag 2: This bag does make its way to landfill(垃圾场). Before they have a chance to cover up the thousands of pounds of daily waste, a strong wind comes up and blows these plastic bags out of the landfill. Once the wind stops, workers will be sent to collect thousands of bags around. But they can’t possibly get them all. So our little bag continues his adventure getting caught in trees, eaten by birds or making its way to our lakes or rivers.
Plastic Bag 3: The last bag also blows away but is caught in a landfill where it sits for many years, as all the trash is wrapped in a big plastic bag, making natural degradation(降解) impossible. Although workers do much work to make sure water and air system won’t be polluted, some do. Guess what, plastic bags are made from petrol, a harmful waste material, which in one way or another makes its way to the environment.
Another problem with putting plastic bags in out trash is that our landfills for most cities may be filled in about 20 years. More importantly, since we are running out of land to build homes, you might have the pleasure of one day living on top of your plastic bags!
One of the best suggestions is not to use a bag at all or bring your own cloth bags. If you must, please choose paper bags, which, though not suggested, can be eaten by animals. And there are more opportunities recycle paper bags. It does take a little extra effort. But please have a thought about the little seal next time you say, “Plastic please.”

A. He can use plastic bags to carry trash later.

71. The author describes the travel of Plastic Bag 1 to show ______.
