They describe statistics surrounding porn use as "terrifying," quoting data provided by the American Psychological Association.
Porn consumption rates are between 50% and 99% among men and 30% to 86% among women, they say, "with the former group often reporting less satisfactory intimate lives with their wives or girlfriends as a result of the consumption".
They describe today's younger generation as "the crack babies of porn" - children "being raised in an environment of wall-to-wall, digitized sexual images".
In a statement released on the Pamela Anderson Foundation website, the 49-year-old said she was glad to join forces with Rabbi Shmuley to raise public awareness of "the innocent lives this has destroyed".
She said: "Something must be done immediately.
"A healthy, loving sexual experience demands both intimacy and respect, both of which pornography addiction destroys."
Anderson is
Playboy's most prolific cover girl, having first posed for the publication in 1989.
She graced the cover and centrefold of the magazine's final nude issue last year, after it announced it was ending the tradition of publishing nude photographs due to the availability of free images online.
Anderson has also had two sex tapes leaked, including one from her honeymoon with her then-husband Tommy Lee in 1995.
She is due to make a comeback in the big screen
remake of Baywatch, also starring Dwayne "The Rock" Johnson, with the film due out next year.
