OPINION
Joseph H. Mentó, III, was convicted in the district court of possessing child pornography, in violation of 18 U.S.C. § 2252A(a)(5)(B). Mentó entered a guilty plea to the charge, reserving the right to appeal the lower court’s determination that the statute, as amended by the Child Pornography Protection Act of 1996 (“CPPA” or “the Act”), is constitutional on its face. The federal courts of appeals that have considered this issue are split on its proper resolution. The First and Eleventh Circuits have upheld the Act against constitutional challenge, but the Ninth Circuit has struck down the CPPA as an unlawful abridgement of the free-speech guarantees secured by the First Amendment. We conclude that the Act passes constitutional muster, and we affirm the judgment of the court below.
I.
A.
In December 1997, the FBI received information from a confidential informant that Mentó was in possession of child pornography; federal agents thereafter obtained a warrant authorizing the search and seizure of certain items in Mento’s home. Upon execution of the warrant, Mentó admitted to possessing child pornography, and he advised the agents how to access the material on his computer. The ensuing search of Mento’s computer, external drives, and disks yielded more than one hundred images of naked, prepubescent children in sexually explicit situations. A number of these images depicted the children engaged in overt sexual acts with adults and with each other. According to a caption accompanying the images, one of the children was only five years old. Mentó had downloaded the images from the Internet.

Since 1977, Congress has attempted to eliminate child pornography. See Protection of Children Against Sexual Exploitation Act of 1977, Pub.L. No. 95-225, 92 Stat. 7 (1978). In New York v.
In the wake of Ferber, Congress amended the federal child pornography law to include aspects of the Court’s decision. See Child Protection Act of 1984, Pub.L. No. 98-292, 98 Stat. 204 (1984).
Then, in 1996, the CPPA was enacted to address the entirely new problems posed by technological advances. Congress was concerned, inter alia, with the practice of digitally altering photographic images to create child pornography out of innocent photos of children. See 110 Stat. 3009-26. Spurred by testimony that such material may be used by adults to entice children into sexual behavior, id., Congress expanded the definition of child pornography to include not only altered pictures of identifiable children, but also depictions of what “appear to be” minors. This latter category encompasses wholly artificial images, created without the involvement of an actual child.
Hence, the term “child pornography” now includes “any photograph, film, video, picture, or computer or computer-generated image or picture” where:
(A) the production of such visual depiction involves the use of a minor engaging in sexually explicit conduct;
(B) such visual depiction is, or appears to be, of a minor engaging in sexually explicit conduct;
(C) such visual depiction has been created, adapted, or modified to appear that an identifiable minor is engaging in sexually explicit conduct; or
(D) such visual depiction is advertised, promoted, presented, described, or distributed in such a manner that conveys the impression that the material is or contains a visual depiction of a minor engaging in sexually explicit conduct.
18 U.S.C. § 2256(8) (emphasis added).
The statute prohibits the transportation of child pornography in interstate or foreign commerce (including the Internet), as well as its receipt, sale, distribution, reproduction for distribution, or possession with intent to sell. 18 U.S.C. § 2252A(a)(l)-(4).

Mentó argues that the CPPA, as a content-based restriction on speech, cannot survive the exacting standards of strict scrutiny review. Moreover, according to Mentó, the Act is impermissibly overbroad and vague insofar as it criminalizes any visual depiction that “appears to be” child pornography, or that is transmitted in such a way as to “convey the impression” of being child pornography.
After judgment was entered against Mentó in the district court, two other courts of appeals published decisions on the issues raised here and in Hilton. In United States v. Acheson,

A “content-based” restriction on speech is subject to strict scrutiny review. Ward v. Rock Against Racism,
The CPPA bans an entire category of expression — all child pornography — based on its content. Blanket suppression of an entire category of speech unquestionably constitutes a content-based regulation. Hilton,
B.
The First Amendment is the bedrock upon which our political system is founded; its affirmation of free expression permeates our very culture. Limitations imposed on speech because of its content are therefore subject to strict scrutiny, that is, no such limitation is valid unless it is narrowly tailored to serve a compelling government interest. Boos,

The Supreme Court has often recognized the government’s compelling interest in protecting children from harm. See Santosky v. Kramer,
The CPPA was designed by Congress to serve all of these interests. Courts and commentators have examined the legislative history of the Act, identifying its primary purposes as follows:
(1) to prevent the use of virtual child pornography to stimulate the sexual appetites of pedophiles and child sexual abusers;
(2) to destroy the network and market for child pornography;
*919 (3) to prevent the use of pornographic depictions of children in the seduction or coercion of other children into sexual activity;
(4) to solve the problem of prosecution in those cases where the government cannot call as a witness or otherwise identify the child involved to establish his/her age;
(5) to prevent harm to actual children involved, where child pornography serves as a lasting record of then-abuse; and
(6) to prevent harm to children caused by the sexualization and eroticization of minors in child pornography.
See, e.g., Hilton,
Mentó nonetheless contends that the government’s true purpose in combating child pornography has impermissibly shifted from preventing tangible harm to real children, toward eradicating certain ideas that it considers inherently evil.
Mentó interprets Ferber too narrowly. Ferber necessarily dealt only with depictions of actual children, long before virtual pornography became an issue. Viewed in the proper context, Ferber in no way stands for the proposition that permissible governmental interests in the realm of child pornography would be forever restricted to the harm suffered by identifiable children participating in its production.
To the contrary, the Supreme Court has mandated that a degree of flexibility be
2.
Congress may regulate protected speech to promote a compelling governmental interest so long as it selects “the least restrictive means to further the articulated interest.” Sable Communications of Calif., Inc. v. FCC,
The Supreme Court has approved as narrowly tailored the banning of child pornography, including its possession, in part because of the causal link between child pornography and the sexual abuse and exploitation of children. Therefore, the question is whether there is any substantial difference between child pornography in the traditional sense and child pornography where the minor is “virtual.”
Congress has found that pornography involving actors who “appear to be” minors has all of the same effects on child molesters as actual child pornography.
[T]he effect of visual depictions of child sexual activity on a child molester or pedophile using that material to stimulate or whet his own sexual appetites, or on a child where the material is being used as a means of seducing or breaking down the child’s inhibitions to sexual abuse or exploitation, is the same whether the child pornography consists of photographic depictions of actual children or visual depictions produced wholly or in part by ... computer.
110 Stat. 3009-26, -27. To the viewer, there is no difference between a picture of an actual child and what “appears to be” a child. Similarly, depictions that are represented to be minors are harmful in the same way as any child pornography, except that there is no minor involved in their production. See Hilton,
Logically, then, the connection between virtual child pornography and the sexual abuse of children is as powerful as the causal link that justifies the utter prohibition of pornographic images involving actual child participants. Unfortunately, technological advances have resulted in an enforcement problem, which the government refers to as an “epistemological conundrum.” Without the benefit of the “appears to be” language in the CPPA, there is frequently a built-in reasonable-doubt argument as to the age of the participant, unless the government can identify the actual child involved. If the identity of the actor is not available, often the government can prove nothing more than the depiction “appears to be” that of a minor.
In light of recent improvements in technology, “efforts to eradicate the child por
The ban on material that “appears to be” child pornography or “conveys the impression” thereof may indeed affect some pornography where adults pose in a manner designed to simulate children. The government, however, has the same compelling interest in banning this material because it satisfies the audience for child pornography, resulting in the same negative effects on minors generally. In sum, we conclude that the CPPA represents the least restrictive means of advancing the vitally important government interest of effectively protecting minors from sexual exploitation and abuse.
C.
Mentó next contends that the “appears to be” and “conveys the impression” language renders the CPPA unconstitutionally overbroad. In order for a statute to be invalidated on its face, its overbreadth must be real and substantial when judged in relation to the statute’s plainly legitimate sweep. Ferber,
We agree with the First Circuit’s rationale in Hilton that, although not explicitly stated in the statute, the “appears to be” language of the Act bans only those images that are virtually indistinguishable from previously banned photographic depictions; it does not outlaw items such as drawings, cartoons, or paintings. See S. Rep. No. 104-358, at pt. IV(C) (“[T]he appears to be language applies to the same type of photographic image already prohibited, but which does not require the use of an actual minor in its production.”).
There is no question that the CPPA criminalizes certain images that resemble true photographs, but are in fact altered from various innocent and unrelated sources, and thus produced in a manner that did not harm any child. Consequently, the Act prohibits material that is predominantly the product of the creator’s imagination — an array of complex computer images whose composition requires a degree of artistic skill. Nevertheless, artificial depictions of child pornography that cannot be easily distinguished from the real thing do not deserve the protections of the First Amendment because, “like sexually explicit material produced with actual children, there is little, if any, social value in this type of expression.” Hilton,
With regard to “real” depictions involving young-looking actors of uncertain age, the Act offers an affirmative defense to sellers, producers, and distributors who can provide proof of the participants’ majority. Admittedly, this defense is unavailable to mere possessors. See supra note 4. There is, therefore, a slight risk that a person could be convicted of possessing “child” pornography that was actually produced using adults.
This risk could only be eliminated, however, if the statute were to offer safe harbor to possessors of teen pornography where the actors are not identifiable. Such an approach would do nothing to prevent the sexual exploitation of teenagers and other minors, and it would permit the market for child pornography to thrive. As a result, compelling government objectives — including the protection of minors who may seem sexually mature — would be thwarted. See Hilton, 167
D.
To avoid being unconstitutionally vague, a statute must provide clear and adequate notice of the activity it prohibits. Although the Constitution does not impose “impossible standards of clarity” on Congress, ordinary people should understand the prohibitions, and the statute should not encourage arbitrary enforcement. Kolender v. Lawson,
We conclude that the CPPA provides clear and adequate notice of the activity it regulates, such that ordinary citizens and those charged with enforcing the law may readily understand what is prohibited. Because it meets the Constitution’s specificity requirements, the Act is not void for vagueness.
First, the Act explicitly lists the elements of child pornography, specifies “minor” as a person under the age of eighteen, and particularly defines the sexually explicit conduct that will not be condoned. 18 U.S.C. § 2256(8). Precisely four categories of material depicting such conduct are banned: actual pictures of actual minors, altered pictures of actual minors, pictures appearing to be of minors, and pictures that are represented to be minors.
Second, those who mail, transport, receive, sell, distribute, or reproduce the material are protected if they can show the actor was actually an adult and the material was not represented to be a depiction of one or more minors. 18 U.S.C. § 2252A(c). Because an affirmative defense is also available to those charged with mere possession, see supra note 4, it is highly unlikely that innocent persons who inadvertently stumble across prohibited materials will be convicted.
Third, the legislative history of the CPPA shows that by using the words “appears to be,” Congress intended only to include those images “virtually indistinguishable to unsuspecting viewers from ... [altered] photographs of actual children engaging in identical sexual conduct.” S. Rep. No. 104-358, at pts. I, IV(B) (emphasis added). We do not understand the statute to criminalize any sexually explicit depictions that are not virtually indistinguishable from photographic child pornography.
Fourth, we believe the “appears to be” language connotes an objective standard. As in any felony case, the prosecution must establish the element of scienter to obtain a conviction. See United States v. X-Citement Video, Inc.,
The CPPA is indeed bold and innovative in its attempt to combat the sexual exploitation of minors caused by the trade of child pornography. Boldness and innovation, however, do not render an Act of Congress constitutionally infirm. We hold that the CPPA does not impermissibly regulate protected speech and does not, therefore, offend the First Amendment. Consequently, we affirm Mento’s conviction of illegally possessing child pornography.
AFFIRMED
Notes
. Although adult pornography is protected by the First Amendment, obscenity is not. Miller v. California,
. Among other things, the amendments replaced the word "lewd” with "lascivious” to describe an aspect of the banned materials; substituted the phrase "visual depiction” for "visual or print medium”; enlarged the definition of "minor” to include persons under eighteen; and brought non-commercial pornography within the ambit of the statute.
.“Sexually explicit conduct” is defined as actual or simulated;
(A) sexual intercourse, including genital-genital, oral-genital, anal-genital, or oral-anal, whether between persons of the same or opposite sex;
(B) bestiality;
(C) masturbation;
(D) sadistic or masochistic abuse; or
(E) lascivious exhibition of the genitals or pubic area of any person.
18 U.S.C. § 2256(2).
. An affirmative defense exists for those traffickers who can prove the material was produced using only adults, provided that the accused did not otherwise violate the statute by advertising, promoting, presenting, describing, or distributing the material in a manner to convey the impression that it contained a visual depiction of a minor engaging in sexually explicit conduct. 18 U.S.C. § 2252A(c). For those charged with simple possession of child pornography, that defense is not available; instead, an accused in Men-to’s shoes may avoid conviction by demonstrating that he (1) possessed fewer than three such images; and (2) promptly and in good faith destroyed or reported the images to law enforcement. § 2252A(d).
. Mentó does not contest that he knowingly possessed images of actual minors. Indeed, we would uphold Mento's conviction even if we determined the statutory language in question to be unconstitutional; the statute could be severed accordingly. See Free Speech Coalition v. Reno,
Mento’s First Amendment attack on the CPPA encompasses the argument that the Act is impermissibly vague, a defect that is also alleged to be a deprivation of his Fifth Amendment right to due process. We note, however, that Mentó does not possess standing to raise a Fifth Amendment claim; the severability of the Act deprives him of any legally cognizable interest in the outcome. County of Los Angeles v. Davis,
. The government argues that the CPPA is content-neutral insofar as the Act seeks to regulate the secondary effects child pornography has on pedophiles. In support of its view, the government cites the Supreme Court's decisions in Renton and City of Erie v. Pap’s A.M., 529 U.S. 277,
. Mentó maintains that the regulation of ideas — even bad ones — is per se unconstitutional. In support of this position, Mento cites American Booksellers Ass’n, Inc. v. Hudnut,
Mento’s argument misses the mark. The Seventh Circuit invalidated the ordinance as contrary to the Supreme Court’s admonition in Miller that only obscene depictions of adult pornography can be regulated out of existence:
True, pornography and obscenity have sex in common. But Indianapolis left out of its definition any reference to literary, artistic, political, or scientific value. The ordinance applies to graphic sexually explicit subordination in works great and small. The Court sometimes balances the value of speech against the costs of its restriction, but it does this by category of speech and not by the content of particular works.
