Question Description

BIO 1302 UNIT 3

JOURNAL

Consider humanity as the ultimate predator. Many if not most of us, particularly in the United States, are quite comfortable with the harvesting of organisms like tuna, deer, ducks, or rabbits. Other countries and cultures, however, value species that rarely, if ever, find their way to the North American dinner plate. What are your thoughts on the harvesting of organisms such as whales, dolphins, seals, etc.? Is hunting the only major issue that might threaten the existence of these organisms? Should we limit ourselves to eating only certain organisms? Why, or why not? In what ways are you selective about the foods you eat?

Your journal entry must be at least 200 words. No references or citations are necessary.

UNIT 3 HOMEWORK

  • Introduction

In the Unit III Lesson, you learned about the overfishing and decline of the Atlantic Cod off the coast of Nova Scotia. Other populations of fish around the world have been affected in much the same way. This activity will help you explore which species are imperiled by current fishing practices and which are, for now, a relatively sustainable choice for the table.
