SAN DIEGO -- A television advertisement blaming immigration for overcrowding in California is causing quite a stir, 10News reported.

The ad, paid for by Californians For Population Stabilization, (CAPS), is currently airing on another television station in San Diego County, and has prompted viewers to call 10News to express their concerns.

The commercial begins with a child asking basic questions, but the message of the ad is unmistakable.

"If Californians are having fewer children, where are all the people coming from?" the child asks. The commercial then states that 98 percent of the population growth is from immigration.

Dr. Stuart Hurlbert is a San Diego State University professor and board member of CAPS.

"We're adding to California a city the size of Los Angeles every decade. What is producing this tremendous population growth is almost entirely immigration and births to first-generation immigrants," Hurlbert said.

He said that the ad is an education campaign about the downside of unchecked population growth: more traffic, pollution, and environmental impacts.

Christian Ramirez of the American Friends Service Committee sees the ad differently.

"These kinds of videos and messages are obviously racist. They play up the fears of people," Ramirez said.

He feels the ad is harmful by inciting people to place full blame for California's current economic and social problems on immigrants.

"Obviously, the video is trying to portray that migrants are somehow responsible for lack of schools, lack of housing, overcrowding, and that's simply not the case in the state of California," Ramirez said.

Hurlbert dismisses the racism charge, saying that the numbers don't lie and if left unchecked, California will add another 16 million people by the year 2025.

"I know if I haven't been called a racist any given week, I haven't done my job. It's playing that card -- that is I think is a good indication of the moral and intellectual bankruptcy of the people who want an unlimited number of people to come into the country," Hurlbert said.

Both Hurlbert and Ramirez told 10News that they oppose illegal immigration and believe the state needs better written and better enforced immigration laws. However, they disagree on the method being used to get out the message.
