Question 1

Pollution in Lake Washington resulted from:

Accepted Answer

B)  a population explosion of resident freshwater fishes. 
C)  excessive boat traffic. 
D)  large bird populations inhabiting the waters of the lake.

Question 2

In addressing environmental problems, several stages can be followed. For example, when it was discovered that the rat population on the island of Pumehana was out of control, scientists assessed the problem and formulated a model that suggested if a rat predator is introduced, then the rat population will be significantly decreased. The next step in addressing this environmental problem might be:

Accepted Answer

A)  action. Scientists sprinkle rat poison throughout the island. Several residents die. 
B)  public education and involvement. Hold town meetings to inform island residents the costs of rat predator introduction, a rat sterilization program, rat bounty program, or no intervention. 
C)  political action. A rat-infested island does not lure tourists so something MUST be done. 
D)  a risk analysis. If a mongoose is introduced to control the rat, what are the possible effects of this intervention? 
E)  evaluation. After the release of the initial mongoose population, it is discovered that the mongoose is NOT a rat predator.
