Apparently the government of Mexico is now complaining about the potential harm to "eco systems" that both countries share... if the US continues to build the fence as mandated by Congress and by the will of the majority of US citizens..

Even the (leftist) President of Argentina, visiting Mexico this week, called the fence an insult to all nations..... He is traveling with his wife so foreign nations so as to "expose" his wife to foreign experience, since she is scheduled to be a candidate to replace him after his mandate expires...

As Lou Dobbs pointed out, the worst damage has already been done by those good-hearted immigrants who force themselves across our borders and destroy private and public property in the proces.... leaving an estimated 25 million tons of trash along the US border....

What Lou should be proposed is this: demand that DHS and EPA organize some of those "illegals" in the US to pick up their trash on the way back to Mexico...
