Yes - abortion and other evil acts by humans to humankind. But those abominations have not reduced the population overall. I believe the statistics in my reference show the birth rate is presently double the death rate.
Posit that perhaps the “Gay Marriage” phenomenon is supposed to reduce abortions and the birthrate - but then we have IVF etc., for gays & lesbians. Frightening how modern man has become addicted to perverted personal convenience rather than Christian conscience (or natural selection).
However I do agree with your concerns regarding IVF, and especially using females as surrogates to create children for homosexual couples. There is something about people that is so paradoxically self destructive yet still the procreative instinct exists even in the most flawed of humans.
