Ease of access to pornography is today's online world is deviating people from being constructive and think intellectually. Pornography can't be ban completely nor it should be. But it is becoming is becoming a hindrance for a nation growth or our world growth. Most of the youth waste their resources and time in such things rather than focusing on how to develop more and advance in science, culture, arts, etc.
Pornography is not issue only for youth. Due to high demand and ease of access it is leading to high rise in human trafficking and more people being associated with this industry.
If government agencies limit the pornographic content available online or ask the user identification before accessing those content, then it will surely limit the youth from following such thing.
