Keystone Pipeline Rejected By Prominent Individuals (PHOTOS)

While environmentalists, celebrities and religious leaders may come from different backgrounds, a number of them share something in common: Their opposition to the planned Keystone XL pipeline that may soon be built across the Midwest.

The prominent individuals below have all lent their names to the opposition of the Keystone pipeline, which has pitted many environmentalists against business and oil industry proponents in an increasingly heated debate.

On October 6, the U.S. State Department held its final public hearing on the planned pipeline that will run from Canada to the Gulf coast. The Obama administration has the final say on the pipeline, but experts believe it will be built.

A former Keystone pipeline inspector told HuffPost last month that several leaks on the Keystone pipeline can be traced to construction shortcuts. He said he has "no faith" that TransCanada can build a pipeline properly.

HuffPost's Tom Zeller reported that a study by a University of Nebraska-Lincoln engineering professor found that "the worst-case spill scenarios contemplated by TransCanada ... are grossly underestimated -- and that hundreds of rivers, streams and aquifers are vulnerable to toxic oil contamination."
