Synopsis
- This article examines how Brazil's environmental agency approved offshore oil drilling near the mouth of the Amazon River despite risks to a rare population of manatees.
- Students learn that the manatees living in this area are hybrids of the marine West Indian manatee and the freshwater Amazonian manatee, carrying a unique genetic code adapted to the region's mix of salt and fresh water.
- The article describes a wildlife-rescue simulation and the concerns scientists and regulators raised about protecting large marine animals in the event of an oil spill.

Teaching Materials
Classroom Implementation:
- Use the article to launch a discussion on trade-offs between energy development and biodiversity protection, asking students to identify the stakeholders named and their point of view.
- Have students analyze the concept of a hybrid population and why a locally adapted genome matters for conservation, connecting it to ideas about genetic variation and species survival.
Extensions:
- Ask students to evaluate the wildlife-rescue plan described and design or critique criteria a stronger emergency response plan would need to meet.
- Alternatively, have students develop a wildlife safety plan for a local development, such as a new shopping mall.
Related Resources:
- Use this article to explore a further challenge for protecting biodiversity in the Amazon: chronic underfunding despite legal protection.
- Read this article about the Endangered Species Act to launch a discussion about how species (including the manatee) are legally protected in the United States; then, discuss how these protections have been weakened recently using this short news article.
The article highlights the potential negative environmental impacts of the oil industry and the complexity of cleanup efforts after a spill. The article briefly mentions the legal process for project approval and appeals related to environmental risk.
