Establish Prior Knowledge
Call on students to share what they know about mangrove forests. Discuss the value of mangroves with students. Tell students that the Bio Snapshot they are about to see describes the destruction of mangroves in Thailand to make room for shrimp farming. It also explains what researchers are proposing to balance the needs of both the mangroves and the shrimp farms.
Have students view the snapshot and read the synopsis. Use the following questions to guide a class discussion:
- What did the coastline on the map from 1976 show?
- Why are mangroves important to the coastline, especially in tsunami prone regions?
- What do researchers propose to balance the economic benefits of mangroves and shrimp farms?
Use the following question to guide further discussion:
- Think about the area in which you live. Is there a place where economic development and the environment are at odds? What solutions can you come up with?
