Professor/a, espera-se que os/as estudantes pensem sobre as diversas formas de energia presentes em seu dia a dia. Por exemplo, para gerar eletricidade, dependendo da localidade, pode-se considerar o uso da energia hidroelétrica, eólica, solar, nuclear ou termelétrica; as pessoas que usam condução para ir à escola dependem do petróleo, do álcool ou do gás natural etc. É possível trabalhar em conjunto com o/a professor/a de Geografia, que pode contribuir para essa conscientização.

Discuss

What sources of energy do you use in your daily life?

In your opinion, what is the best/worst/safest/most dangerous source of energy?

What would an ideal source of energy be like?

Does your community experience problems with energy supply? If so, what could be done to minimize them?

Why is it important to save energy?

Professor/a, de forma geral, espera-se que os/as estudantes concluam que o ponto positivo das formas de obtenção de energia apresentadas se relaciona, em muitos casos, à geração de empregos e de riqueza ou conforto material, mas o preço que se paga por isso é a piora da saúde do meio ambiente e, consequentemente, de todos, especialmente das comunidades que vivem nos arredores das áreas exploradas. Respostas pontuais para os itens “a” e “b” encontram-se junto de cada excerto.

a) Mining (Serra Pelada). b) Positive aspects: 29,000 tons of gold from 1980 to 1986 were extracted; and it employed 50,000 workers. Negative aspects: it is one of the main causes of deforestation because trees and vegetation are cleared and burned; they use chemicals that are often discharged into rivers, streams, bays, and oceans, which contaminates all living organisms including the people who depend on the fish for their main source of protein and their economic livelihood.

I “[…] An example of a large scale mine is the Serra Pelada mine in Brazil which yielded 29,000 tons of gold from 1980 to 1986 and employed 50,000 workers […].

Mining is generally very destructive to the environment. It is one of the main causes of deforestation. In order to mine, trees and vegetation are cleared and burned. With the ground completely bare, large scale mining operations use huge bulldozers and excavators to extract the metals and minerals from the soil. In order to amalgamate (cluster) the extractions, they use chemicals such as cyanide, mercury, or methylmercury. These chemicals go through tailings (pipes) and are often discharged into rivers, streams, bays, and oceans. This pollution contaminates all living organisms within the body of water and ultimately the people who depend on the fish for their main source of protein and their economic livelihood.”

II “Hoover is a miraculous giant thumbnail that happens to have transformed the West. Take it away, and you take away water and power from 25 million people. Take it away, and you remove a slice of American history, including a piece of the recovery from the Depression, when news of each step in the dam’s construction […] heartened hungry and dejected people across the country. And take away the jobs the dam provided ten or fifteen thousand workers, whose desperation compelled them to accept risky, exhausting labor for four dollars a day […].

In seven decades we have learned that if you take away Hoover, you also take away millions of tons of salt that the Colorado once carried to the sea but which have instead been strewn across the irrigated landscape, slowly poisoning the soil. […]

Take away the dams, and the Cocopa Indians […] might have a chance of avoiding cultural extinction. Take away the dams, and the Colorado would again bring its nutrients to the Gulf of California, helping that depleted fishery to recover the status it held a half-century ago as an unparalleled repository of marine life. Take away the dams, finally, and the Colorado River returns to its virgin state: tempestuous, fickle, in some stretches astonishing.”

a) Hydropower generation (Hoover Dam). b) Positive aspects: water and power to 25 million people in the West; its construction helped the country’s recovery from the Depression, providing jobs to 10 or 15 thousand workers at the time of its construction. Negative aspects: millions of tons of salt that the Colorado River once carried to the sea have been slowly poisoning the soil; the Cocopa Indians threat of cultural extinction; depleted fishery; and the fact that the Colorado River lost its virgin state: tempestuous, fickle, in some stretches astonishing.

III “Texas contains an abundance of natural resources, but efforts to impose environmental regulations have faced roadblocks for many decades.

Texas holds a large share of the nation’s oil and chemical manufacturing industries, so state policymakers must balance economic considerations with the need to curtail environmental risk. Oil, gas and chemical manufacturing industries employ thousands of Texans and contribute billions to the Texas economy. State leaders also want to continue to attract new industries, complicating efforts for more environmental regulation.

The state’s two largest environmental issues are dirty air and an endangered water supply. Environmental groups are also critical of the state’s centralized environmental regulation at the Texas Commission on Environmental Quality, complaining that the agency favors economic development over environmental protection.”

4 Based on this diagram, how would you define “sustainability”? How does this concept relate to the information presented in the previous extracts?



Professor/a, espera-se que os/as estudantes percebam que, segundo o diagrama, a sustentabilidade está relacionada ao equilíbrio entre aspectos sociais, ambientais e econômicos, visando a conservação e o uso consciente dos recursos do planeta e sua preservação para as gerações futuras. Tal equilíbrio, de acordo com os excertos da atividade 3, é difícil de ser alcançado.
