Right now the Supreme Court in the United States is debating Roe v. Wade. Roe is the only protection women have to control their own bodies in the USA.
If we lose Roe 3 things will happen:
1. Women will not have access to healthcare and will die and be permanently harmed from "back street" abortions. Restricting or making abortion illegal doesn't stop them - it just stops safe ones.
2. Miscarriages will be investigated. When abortion is illegal that means that every pregnancy loss must be investigated to ensure the "crime" of abortion didn't happen.
3. The rich will still have access to abortion.
