CRITICAL THINKING
1. Two arctic marine mammals that live in the same waters
differ in the level of pollutants in their bodies. Bowhead
whales have a lower pollutant load than ringed seals.
What are some factors that might explain this difference?
2. In one seaside community in New Jersey, the U.S. Fish
and Wildlife Service suggested trapping and removing
feral cats (domestic cats that live in the wild). The goal
was to protect some endangered wild birds (plovers)
that nested on the town's beaches. Many residents were
angered by the proposal, arguing that the cats have as
much right to be there as the birds. Do you agree? Why
or why not?
3. In some areas, the barrier built to prevert uncontrolled
movement of people across the border oetween the
United States and Mexico consists of miles of 6-meter-
tall steel beams placed four inches apart. Discuss the
ecological effects of such a barrier. What types of organ-
isms would be most adversely affected by this habitat
fragmentation?
4. The magnitude of acid rain's effects can be influenced
by the properties of the rock that the rain runs over. Acid
rain is least likely to significantly acidify lakes in regions
where there is a large amount of calcium carbonate-rich
rock. How does the presence of these rocks mitigate the
effects of acid rain?
