700 mile fence part two

I am against illegal immigration. I don't think that a fence would solve the problem though and I think that a fence is morally wrong because it will force immigrants to cross at more dangerous places. I think that building a fence is also wrong because it disrupts migration patterns of dessert animals that need to get to water on either side of the border. I think that instead of building a wall, the united states should work to help mexico to fight poverty so that people in mexico aren't motivated to come to the united states.
