1) Hunting: People can over-hunt a species killing too many of them too fast.
2) Global warming: A place can get to hot for them to survive their anymore like coral reefs for example.

Redistricting is the process by which new congressional and state legislative district boundaries are drawn. All United States Representatives and state legislators are elected from political divisions called districts. District lines are redrawn every 10 years following completion of the United States census. The federal government stipulates that districts must have nearly equal populations and must not discriminate on the basis of race or ethnicity.[1]
See the sections below for further information on the following topics:
Background: This section summarizes federal requirements for redistricting at both the congressional and state legislative levels. In addition, recent court decisions affecting redistricting policy are summarized.
Methods: This section provides details about the various redistricting processes used in the states.
Competitiveness: This section summarizes some of the arguments about the impact of redistricting on electoral competitiveness. Margin-of-victory and competitiveness data for congressional and state legislative elections is provided for informational purposes.
Majority-minority districts: This section summarizes the legal basis for the creation of majority-minority districts and details some of the arguments surrounding the practice.
Based on maps I looked on, it seems that San Antonio, Texas, is the closest.
The correct answer is - They formed long ago, and erosion has beveled them to their present elevation.
The Appalachian Mountain Range is one of the oldest mountain ranges on the planet. They have formed in the Ordovician Period, around 480 million years ago. When they formed and were at their peak, the Appalachians were much larger and higher than what they are in the present. The reason for their decline in size is attributed to the erosion. The erosion is a process that removes the material from its original position. This process has been influencing, at different rates, the Appalachians for almost half a billion years. Even though the erosion is not a process that acts very quickly, when put the time that it influenced these mountains we will see that it managed to lower them significantly. That process continues in the present, and in the manner in which the continents are moving, there shouldn't be any force that will help lift up the Appalachians again, but instead they will continue to shrink until they are flattened in the distant future.

Hope this helps.
