This is the most amusing and misguided thing I've read today. Thanks for the laugh.
The Escalante project is dead due to the election (at least for the time being -- the next president may have a different view). Of course even if Escalante was built it would have zero effect on Bright Angel as it is so far away that the two can't be seen from each other. (Except it may actually
improve conditions on BA as tourists might choose Escalante over BA for their inner canyon experience).
You can certainly argue that private development in Tusayan, as well as potential uranium mining, would have a huge impact on the Grand Canyon, especially with regards to water, springs, pollution, light, etc. but if all of that happens the one thing that is least likely to be affected at all is the Bright Angel trail. It is already a highly developed and managed tourist attraction.
I don't know about any of the other places on this list but it makes me doubt the accuracy of the whole article.
