Tips & Modifications
For struggling readers, have them annotate the reading by circling new vocabulary and underlining important phrases or sentences. They can also be paired with more confident readers to help process the text.
This activity works best in small groups. Cooperative learning benefits advanced learners and struggling readers. Assign groups so that advanced students are grouped with struggling readers.
1. Have students discuss what they learned in Activities 1 and 2.
Set the stage by reviewing the sequence of activities within this lesson. Remind students that at the beginning of this lesson, they explored a decision through one stakeholder’s viewpoint. They then learned more about the area both geographically and politically, analyzed each stakeholder’s influence and connection to the decision, and then identified cultural, economic, and environmental consequences of the decision to place a road in the Amazon. In this activity, they will pull together what they have learned in the previous activities to complete the analysis of the decision about the Pucallpa-Cruzeiro do Sul road in the Amazon. Place students in groups of three, and assist them through the following process as a group. Each group of three will hand in a decision statement at the end of this lesson. Ask students to pull out their Stakeholder Table and Consequences Webs they developed in Activities 1 and 2. They can use their individual documents as evidence to support the group-level conversations.
2. Have students revisit the information gathered on the influence of stakeholders.
Ask students to have available their Stakeholder Table from Activity 1. Distribute one copy of the Decision Statement worksheet to each group and have students complete Part 1: Stakeholders. Using the information they gathered in Activities 1 and 2, ask students to rate each of the stakeholders’ level of influence within the decision. Remind them that not every stakeholder has a voice or equal influence in the decision. Ask students to reflect on the role these particular stakeholders have played in the decision-making process of building the Pucallpa-Cruzeiro do Sul road.
3. Have students revisit the information gathered from the identification of consequences.
Remind students that all decisions and actions have consequences. Ask students to refer to their Consequences Web from Activity 2. Have them complete Part 2: Consequences in the Decision Statement worksheet by identifying the impact of the consequences upon each of the known stakeholders considering environmental, cultural, and economic factors.
4. Have students create a decision statement.
Explain to students that the product of the decision-making process is a decision statement. A decision statement has three parts: (1) a statement of the decision; (2) evidence that supports the decision; and (3) a statement of who will positively and negatively benefit from the decision considering economic, cultural, and environmental factors. Ask students to complete Part 3: Decision Statement. Remind students in Activity 1, they made a decision from one stakeholder’s perspective. This time, they need to consider all stakeholders’ perspectives. Collect completed Decision Statement worksheets as a formal evaluation of the lesson.
5. Have students reflect upon the decision-making process.
Ask students to refer to the decision statement they created in Activity 1. Ask them to reflect upon everything they have learned in the lesson. Have them compare what they wrote in Activity 1 with their final decision statement in Activity 3. Ask: Did your decision statement stay the same or change? If it changed, what influenced your decision? What additional information affected your thinking? If it did not change, are you surprised? Why or why not?
In this activity, students will complete the final Decision Statement in small groups based on all the information they collected from the previous two activities about the influence of different stakeholders and the consequences of building a road on each of the stakeholders. Final Decision Statements will be collected and assessed using a rubric.
Extending the Learning
- Have students write a persuasive paper to argue for or against building the road from the point of view of one stakeholder.
- Have students conduct further research on local building practices and create an informative campaign (brochure, multimedia presentation, etc.) for or against a local building project.
- Have students use MapMaker Interactive to explore the geography of the Amazon rain forest.

A space that allows students to move freely between these structures is needed. Students may need to access computers while they are constructing their decision statements with their small groups.
- Heterogeneous grouping
- The Amazon rain forest is a carbon sink. The Amazon rain forest plays a crucial role in keeping carbon out of our atmosphere, as it naturally sequesters about 20% of the atmospheric carbon emitted by the burning of fossil fuels elsewhere. But, it can only remain a carbon sink as long as it absorbs more carbon dioxide than it releases. The diminishing rain forest would greatly affect global warming.
- The Amazon is one of the most biodiverse ecosystems in the world. Yet, there are species that live there that are endangered or threatened, including primates such as the spider monkey and red howler monkey. When large trees, like mahogany, are removed, the large canopy that provided shelter, food, or nesting for some of these species disappears, resulting in relocation and possible fragmentation of some populations. Changes made to the ecosystem affect all life that lives there, but for the endangered or threatened populations, these changes could challenge their survival.
- Indigenous communities are scattered throughout the Amazon rain forest. The Ashéninka are one indigenous group whose territory lies at the Peru-Brazil border. They are the second largest indigenous group in the Amazon rain forest (behind the Quechua). Most of the Ashéninka population lives on the Peruvian side of the border, where they hunt, fish, and grow crops for sustenance. Ashéninka territories have been diminishing as loggers, drug traffickers, oil companies, and miners have encroached on their land. As a result, they have retreated deeper into the jungle, where they choose to live in isolation to preserve their cultural traditions and spiritual connections to the rain forest.
- Mahogany, a strong, reddish-brown wood, is found throughout the tropical Amazon rain forest, with dense populations near the Peru-Brazil border. It is valued for its color (hence the nickname, “red gold”) and durability and often used in paneling, furniture-making, and for musical instruments. The United States and Britain are the two largest importers of mahogany. In 2001, Brazil put a moratorium on mahogany exports making Peru the leading exporter. A 2012 World Bank report estimated that 80% of Peruvian timber export stemmed from illegal logging. A conservative estimate in 2000 stated nearly 57,000 mahogany trees were provided to the United States alone.
- Tensions are high between environmental activists who want to protect the rain forest and illegal loggers, miners, and other developers who want to make money to provide a better standard of living for their families and communities. In the past 10 years, over 900 environmental activists have been killed around the world. Peru has had around 60 deaths since 2002, making it one of the top five most dangerous places in the world for people who defend the environment. (Brazil alone has accounted for nearly 450 deaths in this same timespan).
- South America includes thousands of rural communities. Due to poor infrastructure throughout many South American countries, these communities remain weakly connected, if connected at all, to the larger global economy. As a result, these countries have fallen behind other countries that have made decisions to invest in upgrading their highway infrastructure in the global trade market. More roads, or other means of connecting these communities, are needed throughout the continent.
- Knowledge of the conflict around the decision to build a road in the Amazon rain forest
- Identification of stakeholders that could be influenced by the decision to build a road in the Amazon rain forest
- Identification of potential cultural, environmental, and economic consequences of this decision
