Do you know what to do if you see a python (蟒蛇) in your community? What about a seven- foot long American lizard in front of your house? People who live in most areas in the United States do not have experiences like these. But if you live in southern Florida, you may run into a number of exotic (外来的) animals.
Exotic pets have become more and more popular in recent years in Florida. People often buy an animal as a baby without realizing how difficult it may be to care for that animal when it is fully-grown. For example, Burmese pythons are easy to buy at exotic pet stores or online. When the snake is young, it does not require much more work than other pet. But Burmese pythons can grow to be more than 20 feet long and can weigh about 250 pounds. There is not much space in the typical American home or yard to care for such a big animal! When the snake outgrows its cage and its owner becomes bored with caring and feeding it, the snake may be left in a wild area.
In other parts of the country, many of these exotic animals would probably not be able to live long in the wild. But the climate(气候) in southern Florida is wet and warm — similar to the areas where many of the animals are naturally found. Many exotic pets have gradually got used to the new situation in Florida’s natural areas, and when enough of them are free in the wild, they can start breeding(繁殖).
The problem with these unexpected animals is that scientists don’t always know which ones will change or harm the local environment. In the last few years, people visiting Florida’s Everglades National Park have watched fights between American alligators(短嘴鳄) and exotic pythons. It is not hard to imagine the effect of aggressive(凶悍的) animals. But even animals like vervet monkeys, which seem harmless, compete with other animals that eat the same plants. If their presence or behavior causes a change in the habits of local animals, the overall changes can be far-reaching.
Think about a set of dominos (多米诺牌) lined up next to one another, None of them may be touching, but as soon as you tip one over, the whole row will fall down.
