Chapter 7 homework

Chapter 7, Section 1

1. Postindustrial economies put less emphasis on heavy industries and traditional manufacturing and more on service and high-tech businesses. High-tech industries are less dependent on location so that most locations are influenced by weather and nearby-housing. About 75 % of workers are employed in service jobs (government, education, health care, and banking). Many service jobs are located in the central business district of urban areas where the high concentration of office building and retail shops is easily accessible from industrial areas and the suburbs.

2. Expanded trade between countries has led to a global economy which is the merging of economies in which counties are interconnected and become dependent on one another for goods and services. The United States and Canada are involved in trade agreements such as the North American Free Trade Agreement that also includes Mexico, which eliminated trade barriers, increased economic activity, and strengthened their political and economical positions in the global economy. The United States and Canada created the Smart Border action plan to enhance border security.

Creative Writing:
The United States and Canada have market economies which allow people to own, operate, and profit from their own businesses. It allows businesses to hire employees and pay them for their work. Both countries are developing postindustrial economies, which place less emphasis on heavy industry and traditional manufacturing and more emphasis on service and high-tech businesses. A businesses’ ability to hire employees helps the growth and prosperity of service industries. A global economy is the merging of economies in which countries are interconnected and become dependent on one another for goods and services.
Because the world’s economies are interdependent if one country’s economy begins to fail all other economies will be affected and altered.

Chapter 7, Section 2

1. Clear-cutting, which is the taking out of whole forests when harvesting timber, should be eliminate. Once eliminated old-growth forests would not be destroyed and wildlife would be less endangered. Wetlands should be more protected under law to defend against pollution and human interference. People should be more aware of the affects of overfishing and should be limited to the amount of fish allowed to be caught.

2. Industrial development in the United States and Canada has led to an increase in human-made population. Acid rain is formed when cars, power plants, and factories release chemical emissions such as sulfur dioxide and nitrogen oxide that react with the water vapor in the air. It corrodes stone and metal buildings, damages crops, and pollutes soil. It especially damages the region’s waters because plant life and fish cannot survive in highly acidic waters. Smog is also created by the same chemicals that create acid rain. When the sun’s rays interact with these chemicals it forms a visible haze that damages and kills plants and harms people’s eyes, throats, and lungs.

Creative Writing:
The part of the pipeline that is elevated is at some point supported by the permafrost and once it melts supports will become weak and will break leading to the destruction of the pipeline. The part of the pipeline that is frozen underground will become heated and will probably become elevated because once the permafrost melts the land will be less elevated.
