Today, is the final day to submit public comments on the Presidential approval of the Keystone XL tar sands pipeline. Closing at Midnight, the 30-day comment period followed the U.S. State Department's release of the Final Supplemental Environmental Impact Statement (EIS).

Issued in January, the final EIS concluded—to the surprise of many—that the Keystone XL would not increase the rate of tar sands extraction and thus is not likely to significantly increase carbon pollution.

At the end of last month, the inspector general cleared the State Department of any suspected wrongdoing in their selection of the firm, ERM to conduct environmental assessments of the proposed pipeline project.

The inspector general's report came as blow to environmental groups and concerned citizens opposed to the controversial project. In October, groups urged Inspector General Steve Linick to conduct an investigation into the business ties between TransCanada—the company building the pipeline—and ERM, citing conflict-of-interest would cloud the company's conclusions.

Below are three slideshows summarizing nationwide opposition to the Keystone XL pipeline. 

On March 2, more than 1,200 youths from across the country marched to the White House from Georgetown University to protest the Keystone XL. Once there, nearly 400 people were arrested while participating in a nonviolent civil disobedience sit-in:
