Pro-life, please explain

PLEASE don't start arguing, I genuinely want to hear the pro-life reply to this because I don't understand it. I know most all of you believe in these things but for those who do, please try to answer properly i.e. Maturely, no flame wars guys.

I will not be replying, I just want to hear your side.

Personally I wouldn't get an abortion but I am pro-choice up until the stage where a premature baby could survive. I just don't understand why other women are completely anti-abortion though.

-If abortions are banned, dangerous abortions happen, risking the life of that woman. In the past, women used to stick wire hangers up their vaginas to self abort, or throw themselves downstairs onto their stomachs. Many killed themselves or permanently injured themselves in the process because they were desperate enough. There's also the risk of a failed abortion seriously messing up the development of those cells/foetus/embryo. This type of thing used to happen last century and before that and is happening in Ireland today with the ban so I'm not just making it up. Abortions are going to happen no matter what so surely the reasonable course of action is to offer a safe method of doing it?

-Just because you wouldn't personally do something doesn't mean everyone else had to do the same. I don't drink or do drugs but do I go around trying to ban them? Hell no. I have my.opinions but I know that sharing them won't do any good so I don't.

-Making a woman to go through a pregnancy she doesn't want is mentally and physically scarring. What if it was rape? What if it was an abusive relationship? What if her birth control failed? She would probably resent the pregnancy and that foetus/embryo then later child which isn't fair for either of them.

-Just because someone is finding it difficult to conceive does not make it okay to hate on someone who can. Imagine it flipped, imagine a woman who found herself pregnant without wanting to telling a woman who was TTC but failing that she should be grateful for her negative tests?!

-'Just put the child up for adoption' is risking a system-baby. Not enough kids get adopted, many of them have shit starts in life and although some do work out, there are already enough kids waiting to be adopted.

-We're overpopulated. Seriously. All of our environmental problems are due to overpopulation. Wars? Overpopulation. Cruelty in animal farming? Overpopulation. It's all to do with supply and demand and our demand is way too fucking high because 7 billion people is too much. How can you support bringing unwanted children into the world when our planet can't support it? Surely we should try to cut down to only planned pregnancies? That way, the birth rate goes down and we can start decreasing towards a stable population.

I'm not even going to talk about the 'what is it' argument so I'd appreciate it if you didn't bring up (i.e. Bunch of cells or foetus or embryo or baby)
