Summary Introduction
Introduction:
Human interference in the biodiversity is the main reason for increasing species extinction. From fossil records, it can be estimated that earlier extinctions occurred naturally. The rate of extinction was very low million years ago. This is known as background extinction rate and it was about 0.1–1 extinction per million species per year. Evidence of mass extinctions is also found in many species million years ago. Recent rate of species extinction is increasing very rapidly. It is about 100–1000 extinctions per million per year and it is 1000 times more than the background extinction rate.

The Burmese Python, an invasive species, has been introduced to the Florida Everglades, largely through release by owners who acquired the snakes from exotic pet traders. Though the Everglades are protected, pythons as predators can not be easily controlled. What can be concluded about the effect of the python population on the biodiversity of the Everglades?
A. Since the Everglades are protected, python control is limited under laws that protect species in the Everglades.
B. Since the python population is growing, it will eventually become a native species and will increase biodiversity.
C. Since pythons prey on many species in the Everglades, resources will be more available for surviving species and fewer will be considered endangered.
D. Since pythons have no predators, they are responsible for decreasing mammal population and are a greater threat to biodiversity.
