Controversial Topic

I choose to write about birth control for my controversial topic. Young pregnancies is now a common thing seen in society today. 50% of them being unplanned. Birth control can prevent that from happening but why are so many against it? What i already know about this topic is that many mothers today are putting their teenage daughters on birth control at a early age for many reasons. Also many older women are using it for their own safety. There are negative long term consequences that could happen to the body due to birth control. What i would like to find out is why many people are against the use of birth control? The results and effects of having a baby at a young age and what now is being done with birth control.
