New Delhi, Jan 16 : President-elect Barack Obama's `Call for Community Service' appears to have had a huge impact on most of the celebrities, as many of them have vowed to adopt positive changes in their daily living.

Remarkably, more than 50 Hollywood celebrities have pledged to take positive action, in a video from husband-and-wife duo Ashton Kutcher and Demi Moore.

The video will premiere on social networking website MySpace. com, one day before Obama''s inauguration.

While one of the celebrities Eva Longoria has pledged to give up plastic bag usage, Lucy Liu has vowed to use the environment friendly subway when she is in New York.

Soleil Moon Frye, 32, has pledged to support the search for a cure for Alzheimer''s disease, a cause she is already involved in because her father suffers from it, reports China Daily.

The other celebrities who recorded pledges include Cameron Diaz, Dakota Fanning and Eva Mendes, and rock singer Anthony Kiedis of the Red Hot Chili Peppers.

"There''s an assumption that this one man is going to take on his new job full-time and somehow wave a magic wand of change, and I don''t believe that to be true," Kutcher said.

"I think that we have to be the leaders, and that''s not celebrities -- I think that we as citizens have to be leaders of the movement that we want to create," Ashton Kutcher added.

The president of the Los Angeles-based Center for Governmental Studies Bob Stern,, stated that Obama''s call for community service is on the lines of former president John F. Kennedy's the Peace Corps

"I think (Obama''s appeal) could even be bigger, because people criticized Bush and they said, ''Well you don''t really mean it, this is just a way to get government out of things,''" Stern said. "I think this will be more equivalent to Kennedy," Bob said. (ANI)
