Mexican Migration and the Environment

Perhaps environmentalists are happy with the slowing of Mexican migration into the United States, according to the latest reports. Huge numbers of Mexicans, perhaps as many as 12 million are in the United States to work, usually. With economic activity down in the recession, or is it the downfall of civilization, or are we going green? There is less incentive to go to the United States. There are also reports of decline of migration due to the flu scare around the swine flu outbreak in Mexico City. Some say that the more the economy goes down, at least for Mexican migration and for industrial activity, both of these things will go down more.
