Fences are effective means to keep people outside.

There are plenty of opinions about this topic. Read lots and read carefully.

My questions:

1. If a wall (which exists on the border in some areas south of San Diego, for example) doesn't keep people from coming into the country illegally, why would a fence across all 1800 miles be successful?

2. Would a fence interfere with normal migration routes of any animals indigenous to any particular region?

I'm sure you can think of other questions, reasons, counterarguments, etc. Let us know what you come up with.
