I am in the same mindset as Dave Chappelle.
How I feel about abortions depends on who I get pregnant.
I personally wouldn't want someone I impregnated to get an abortion, but agree with OP that earth's population is growing and growing rapidly and we need to not be so careless who we put our seed into.
Currently there are 7 billion people in the world. In 15-20 years, we're expecte to be at 12 BILLION.
Imagine how things are with the resources available. How much things cost based on 7 billion population.
Now imagine in 20 years how expensive things will be because so many people on earth use up resources.
Chances are if you are okay with abortion, you care about future human life.
Chances are if you are not okay with abortion, you care about human life now.
