Abortion in the United States is when someone who is pregnant decides they do not want to continue with the pregnancy and go to a special doctor or clinic to end it. It's like when you take a toy back to the store because you don't want it anymore.
The laws around abortion are different in every state, but in many places, a pregnant person can choose to have an abortion during the first few months of pregnancy. That's because the baby hasn't fully formed yet and is still very small.
Some people believe that abortion should be illegal because they think it's wrong to end a pregnancy. Others believe it should be a choice that the pregnant person gets to make. This can be a very emotional and controversial topic, and people have very strong feelings about it.
No matter what, it's important to remember that everyone's situation is different, and it's up to them to decide what the right choice is for them.
