Google-eyed in the Amazon

Here's an interesting tidbit from an AP article:
Apparently, a Brazilian Indian tribe is teaming up with Google Earth to stop deforestation and mining in the rain-forest. Although the area doesn't have internet access, people hope that images of the rain-forest on Google Earth will have enough impact to stymie the illegal destruction of the land. A case of futile optimism, ulterior corporate motives, or a step in a positive direction? I wonder...
