Everyone talks about how abortion is wrong! WHY?

But no one talks about how hard it is to raise a child alone, the heartache a child goes through missing their father, how many children don't eat because the mother can't provide. Not to mention how many women are in homeless shelters with their children because they can't pay for childcare and rent. Everyone says give it up for adoption. Do you know how many children are abused, molested, and become part of the criminal system due to adoption and bad foster parents. So why is abortion so bad. Yes the woman should have taken the proper precautions but women get pregnant everyday on birth control, after the Plan B pill and even with protection. I never had to make this decision but need help understanding why majority of people believe abortion is wrong? I am not for abortion but need other solutions for women who want to do right but not end up in poverty just to have a child.
