New York, Dec. 25 : A polar bear has warned Santa Claus in a video that global warming is a "serious situation" that could wreak havoc on the environment, including the North Pole.

The warning comes in a three-part video series, "Under the North Star: An Uplifting Christmas Experience".

Critics say the Overland, Mo.-based company behind the animated series has advocated a political stance to children, prompting the removal of the videos.

However, a statement issued by Build-A-Bear founder and CEO Maxine Clark, insists that the video series is intended to "inspire" children to make a difference as individuals.

Maura Flynn, a contributor to BigGovernment. com, called for a boycott of the company, saying the video amounted to "brainwashing on the sleaziest and most sinister" level. (ANI)
