It is likely that humans would presently be extinct on earth without abortions since World War II

 I once calculated that present human populations here on earth would be around 14 to 25 billion presently without any abortions. The problem becomes not just the abortions but any children those non-aborted children have along the way.

Even if you take Pence's (ex vice president's figure) of 62 million legal abortions here in the U.S. since 1973:

2022 minus 1973 is 49 years time that abortions have been legal. 

I was 25 years old before abortions became illegal. I got to witness the abuse first hand of my friends who likely should have been aborted but were not and how tortured many of them were including by cigarettes burned into their hands and arms by their parents who didn't want them and tortured them but were forced by the laws then to raise children they didn't want from ages like 12 to 15 or 16 years of age when they got pregnant. So, I saw how crazy and murderous kids whose parents hated them and tortured them  got during the 1950s and 1960s. I was 2 in 1950 for example.

So, let's mathematically look at 62 million abortions from 1973 to 2022 which is Pence's figure. I have no idea whether this is accurate or not but let's use it as an example.

What happens when you divide 49 years into 62 million abortions?

1265306.12245

So, let's round off to 1,265,306 abortions per year 

on average.

So, add another 1,265,306 people to the population 

of the U.S. in 1973 for that one year. However, for that

one year you have to think in 20 year breeding cycles too.

So, by 1993 you have to realize that these 1,265,306

people begin to reproduce. Let's assume that maybe

1/2 of the people are reproducing by age 20. What

is 1/2 of 1,265,306? it's  632,653. and that's just from 1973 births you now have

1,897,959 people. Now, it's another 30 years almost 

since 1993 which means you add another 632,653 people which is 

2,530,612. And this only takes

us to 2013 folks. We are now 9 years after that!

So, now let's calculate 49 times this for an accurate

account of how many more people would be here in 

the U.S. now (or 2013).

The present population of the U.S. is 329.5 million in (2020).

Now add 123,999,988 for how many new people we

would have as of 2013.

four hundred fifty-three million four hundred ninety-nine thousand nine hundred eighty-eight

or 453,499,988 people instead of 329.5 million now.

So, you see the population by 2013 would have been increased  significantly to where we wouldn't even recognize our nation, especially in regard to crime which is what happens when poor women are not allowed to have abortions 

when they cannot support the child they are pregnant with.

This is also true for the rest of the world. For example, Japan created legal abortions in 1948. Japan would have reproduced itself into oblivion by 1960 or 1970 if they hadn't done this, for example.

Though China didn't create legal abortions until 1988 they told people they could only have one child per family

Here is in regard to China and how they handled the overpopulation problem:

begin quote:

The term one-child policy (Chinese: 一孩政策; pinyin: Yī Hái Zhèng​cè) refers to a population planning initiative in China implemented between 1980 and 2015 to curb the country's population growth by restricting many families to a single child.
