Arguments about when life truly begins or at what point in a pregnancy the foetus becomes a human being, etc., are pointless and they steer us into proposing solutions that aren't solutions at all. The glaringly obvious REAL solution is adopt measures that reduce unwanted pregnancies to vanishingly small numbers. We have to be that ambitious. We do that by making contraception and contraceptive advice freely available, without judgement, and by providing much better education for young people. If you tell people that all contraception is sinful, that abstinence is a virtue and that all sex outside marriage is wrong, then in the next breath condemn abortion, you are nothing less than an unthinking, wicked hypocrite.
