TRASH TRENDS.This chart shows the increase in total waste generation (broken line) from 1960 to 1996. It also shows the changes in individual daily trash generation (solid line). Why do you think we produce more trash today? [GRAPH graph, figure that shows relationships between quantities. The graph of a function y=f (x) is the set of points with coordinates [x, f (x)] in the xy-plane, when x and y are numbers. OMITTED] After reading the story "What a Dump!", and studying the chart "Trends in Trash Generation" above, answer the following questions: 1. How many more tons (Transparent Optical Networking Services) A marketing term for providing dark fiber to a customer.

How many more pounds of trash were generated per person per day in 1980 than in 1970? 3. What happened to individual daily trash generation between 1990 and 1996? 4. Why (to you think trash generation has soared since 19607 List at least two probable PROBABLE. That which has the appearance of truth; that which appears to be founded in reason. reasons for the increase. 5. List three ways to decrease individual trash generation. 6. What happens to more than 50 percent of all trash generated in the U.S.? 7. Within the next 50 years, about how many U.S. landfills will reach full capacity? 8. Why do you think individual daily trash generation decreased between 1990 and 1996? ANSWERS CHECK FOR UNDERSTANDING 1. In 1996, 121.6 more tons of trash were generated than in 1960. 2. In 1980, 0.4 more pounds of trash were generated per person per day than in 1970. 3. Individual daily trash generation declined by 0.2 pounds between 1990 and 1996. 4. Two possible reasons for the dramatic rise in trash generation since 1960 are population growth and increased consumption. 5. Three ways to decrease individual trash generation: reduce, reuse reuse - Using code developed for one application program in another application. Traditionally achieved using program libraries. Object-oriented programming offers reusability of code via its techniques of inheritance and genericity. , and recycle re·cy·cle tr.v. re·cy·cled, re·cy·cling, re·cy·cles 1.
