The atmosphere/company has a great effect on an individual's life. If the company is pious and pure, then the whole life is spent in piety. If only bad company is gotten, then character is destroyed.
Lack of Islamic education and proper upbringing is one of the primary reasons for this problem. The atmosphere of the home is such that the whole time is spent in the misuse of TV, Internet and the phone. This effect of this kind of atmosphere is such that the individual take their first steps on the path of misguidance. The schools and colleges can place a check on this, but alas even there, sex education and coeducation have vitiated the atmosphere. Indecent literature, company of characterless people, etc. drive the individual to even more sins.
Results of sexual relations before marriage:
1. Widespread adultery.
2. Increase in suicide rate.
3. Incurable diseases.
4. Women inclining towards abortion.
5. Familial animosity.
6. Backwardness in education and other areas.
Because of this, adultery becomes rampant in the society. When women become pregnant, they either abort it or end up committing a grave sin like suicide. Then a long series of animosities and differences starts between the families. Many infants have been sacrificed at the altar of death for sins, which they have not committed.
