They have fluids that leak into the watershed and into water courses. As I said. further removal causes additional damage as the tow trucks are forced to navigate previously unspoiled areas of the desert. Interestingly. the illegal immigrants frequently take vegetation from the environment to build shelters. and by taking a lot of the ocotillo cactus. for example. they are removing a very important species from the desert to build these camouflages. drug stashes. and temporary shelters. Also. interestingly. when illegal aliens fill water bottles in the wetland locations. it has been determined that they have actually infected these protected Federal wetlands with invasive parasites and diseases which have been carried with them in the water levels which have harmed native fish and wildlife. In fact. in a report to the House of Representatives committee. according to this report. new tapeworms and fungi have already impacted populations of endangered fish and frogs. So when we talk about the potential damage to the environment from the fences. it is easy to see that there is far more of a benefit than a cost to creating impediments to illegal entry which is creating the kind of environmental impacts I am talking about.
