Gr. 2 Lesson 1-Don't Feed the Gators!:

Students will read a book on the importance of American alligators and listen to-or act out a play which demonstrates the dangers of feeding wild animals.

This is lesson 1 in a series of 3 lessons. Animals in southern Florida are accustomed to their natural environment. They are wild animals with the ability to exist without human intervention. It is detrimental to the American alligator for humans to feed and/or change their natural environment. In areas of southern Florida where American alligators are found, we occasionally hear about problem gators that have attacked dogs and sometimes people. In most of those cases, it is the people who fed the American alligator that are the problem. The American alligators soon begin to associate people with food. When people feed American alligators, they are actually doing it more harm than good. The American alligator no longer gets the balanced diet it would if it were getting its own food in the natural environment. Also, once the American alligator gets used to being fed by humans, it will no longer be able to find food on its own.
