An east Texas landowner was so determined to block the Keystone XL pipeline from coming through his forest that he took to his trees and built an elaborate network of treehouses eight stories above the ground.
"It popped into my head a long time ago, actually," says 45-year-old David Daniel. "If I had to climb my butt on top of a tree and sit there, I would. It started with that."
It turned out to be Daniel's last stand in a long battle against the Keystone XL, a pipeline project that would bring oil from Canada all the way to refineries in the Texas Gulf Coast.
Sometime in the next few months, David Daniel probably will have to stand by and watch as bulldozers knock down his thick forest and dig up the streams he loves.
His East Texas property is one of more than 1,000 in the path of a new pipeline, the southern stretch of what is known as the Keystone XL system.
For years, Daniel has tried to avoid this fate — or at least figure out what risks will come with it. But it has been difficult for him to get straight answers about the tar sands oil the pipeline will carry, and what happens when it spills.
