The US Should Not Have a Border Fence

Well you see the border fence is incredibly expensive.http://usnews.nbcnews.com...The source above shows us that the government has already spent 2.4$ billion on 640 miles, and another 700 miles are to come. This is a massive amount of money, and the benefits of the fence need to outweigh this massive cost. Now, this fence was built (and completed) in 2009. Let us see the amounts of terrorism in the US.Even before this fence was built, terrorism was already declining. [source: http://www.fbi.gov...]Now, let us take a look at the terrorism attack successfulness rate in the US. s://greatpowerpolitics.files.wordpress.com...; alt="" width="487" height="293" />source:http://greatpowerpolitics.wordpress.com...Now let us see another graph on terrorism attacks on the US from the same site. s://greatpowerpolitics.files.wordpress.com...; alt="US Attacks" />You can clearly see a noticable drop at 1972, then at 1993, then a much smaller drop at 2004, and although it does seem that the year the fence was built--2009--the attack had dropped, apparently it really didn't do much to the successful rate, and ever since 2012 there seems to be a gradual rise in the attacks. In fact the exact year the fence was built there seemed to be strange rise of wounded people due to terrorism attacks. s://greatpowerpolitics.files.wordpress.com...; alt="US Wounded" />In fact, the fence seems to do nothing to prevent terrorism deaths and wouds. The site I mentioned before talks about how the fence was made from 2006-2009, and logically if the fence was efficient wounds and deaths should decline. But this is not the case, apprently. s://greatpowerpolitics.files.wordpress.com...; alt="US Casualties" />You see, the deaths and wouds have actually dramatically increased, from 2006-2012, huge peaks, one taller than another, show huge lack of success within the border fence. Not only has the border fence largely failed at preventing terrorism, it has failed to prevent illegal immigration and bought other harms with it.http://www.no-border-wall.com...I'The source above clearly shows us, "97% of people who try to cross the U.S.-Mexico border eventually succeed at entering the country". This only adds to the inefficiency of the border fence, and furthers to why it should not have been built. Furthermore, as the site notes, the fence only redirects the good legal immigrants to horrible places, caused environmental damage, "disturbed ancient graves and archaeological sites", stripping the local people and companies out of their private property, and most disturbingly, the cost to maintain the fence is much much worse than how much it cost to build it. 2.4$ Billion to build the border fence? Oh yeah, but it costs more than $49 billion to maintain the fence, according to the site above. To elaborate specifically on the environmental damage, the border fence actually goes against the Coastal Zone Management Act as it damages the reserve, including marshes and endangered animal as well as plant species. [see: http://www.no-border-wall.com...] Not only so, the cite notes how within the "Smuggler's Gulch", the border fence creates large amounts of erosion due to its need of bulldozing, blasting, among other mechanical actions that heavily damage the environment. The erosion allows water to flow into the environmental site, and in the website's words, "disrupt the twice-daily inundation of sea water upon which its fragile ecosystem depends."IN CONCLUSIONI'm not sure why I was pro on border fence. I guess I just felt like it would be efficient at keeping terrorism and illegal immigrants away. It looks like it is not very efficient after all.Onto you, my opponent.
