DDT was a highly successful pesticide used in 1940’s until its ban in 1972. While highly effective against insects, populations of birds began to decline because of thinning eggshells. On top of that there were concerns about human health. How does the story of DDT show the importance of continued monitoring of ecosystems?

• Monitoring is important to make sure a product is effective

• Monitoring is not important as long as a product is thoroughly tested before being released

• Monitoring is not important because any unintended damage can be fixed when discovered

• Monitoring is important to ensure a product does not have unintended consequences on an ecosystem

Guam is an island in the Pacific Ocean covered in tropical forests. During WWII (1940’s) the green tree snake was accidentally released on the island. Of the 12 species of native birds on the island 10 are extinct and the last two are extinct in the wild. Historically the birds have had little to no natural predators. The large populations of birds would eat the fruit and spread the seeds over large parts of the forest. The snakes’ diet consists completely on birds. With the birds gone many populations of trees are beginning to fall. Which of the following best explains what is happening on Guam?

• Immigration

• Emmigration

• Invasive Species

• Natural Selection
