The act of terminating human life, in its early developmental stage. Proponents of all abortions including non life threatening, non rape, and non incest related situations often believe that life that is yet to be born is worth less than life that has been born. This however is a logical fallacy. The logic goes something like this. Well its just a bunch of cells. It cannot think, it cannot feel, it cannot breathe, it cannot eat, its just a bunch of stuff till it comes out of the womb. However a careful examination of the scientific facts lead to a very different conclusion. From the point of conception, the union of the two haploid cells to form a diploid organism (haploid sperm and eggs are not organisms just means transferring heritable material (DNA) during sexual reproduction) complex cellular events begin that lead to the development of a human being.

This development is continuous and does not end simply when a baby is born, which conflicts with the notion that when a baby is born development is complete. There is no magical reason why a baby cannot be born fully capable of walking. However there are physiological reasons why this would not be a good thing. One, the over development of limbs within the womb would be so great that getting through the birth canal would be impossible and the human species would not be viable. In nature , other organisms are capable of locomotion within hours after birth (horses). Again, different physioligical requirements hence different developmental tasks during gestation within the womb.
To the second point that human life within the womb is incapable of utilization of sensory organs. This is true for the early points of development, however completely false for later portions of development within the womb. Well into the late first and through the rest of pregnancy a fragile human heart has begun to beat literally, and nerve cells have begun to send and receive signals from one another in response to their environment. Moreover many psychology studies have shown that babies within the womb are capable of recognizing the voice of their mothers before and after birth. This is hardly the sign of an organism that is incapable of the use of its sensory organs, in this case the sense of hearing.
I could go on and on. My major point is this. The 5-4 decision of Roe V. Wade was made during at least 40 years ago. In the realm of scientific knowledge, especially knowledge about human development and cellular biology the 1960s and seventies were the dark ages. We simply know so much more, and are only beginning to understand the full capability of early human life which many derisively call a "fetus" in order to con notate it's subhuman status. This is only the beginning of our understanding. The more we know about human life throughout its developmental stages, the more thought we will have to put into terminating it without just cause. Think about it. Pick up a biology book, a Development of the Nervous system book and enlighten yourself. You will find that what is happening in the womb is less like baking cookies in an oven, and more like building an international space station with the building blocks of life, Carbon, Nitrogen, Oxygen, and Hydrogen, and coordinating all the cells and tissues to work together as one seamless entity. Its complicated, and it should be respected. Thank you.

The act of ending an unwanted pregnancy.

to kill a child before it becomes an inconvience.

The act of terminating a life before he or she has had a chance for natural survival. Also a symptom of a society that has failed women. The rate of abortions in the United States could be reduced with logical prevention measures such as single parent housing at universities, more sex education in schools, better state adoption laws and awareness, and better general social support for single parents.

murder for profit

The mass murder of many unborn babies.

The act of terminating a task or objective before it is completed.

The act of terminating the life of an offspring before it is developed enough to leave the womb. Wouldn't be such a big issue if the vast majority of people who undergo it didn't make the stupid decision of fucking without thinking ahead about the consequences, such as getting pregnant as a result.

The termination of a pregnancy. Abortion, at the very least, needs to be left open as an option in cases of rape (so as not to further victimize the woman by forcing her to carry the child of her assailant), incest, and when the mother's life is in danger (as in an ectopic or tubal pregnancy, which will kill the mother if carried to term). Dangerous "back alley" abortions would also result if abortion were banned completely. An interesting contradiction in terms is that supposed "pro-lifers" also tend to be in favor of the death penalty, and have a real bad habit of shooting doctors and blowing up abortion clinics. It's also very difficult to decide exactly when life begins. By Pro-lifer logic, masturbation would probably also be considered murder, as sperm are technically alive and somewhat human (haploid). What they don't seem to understand is that there's a difference between something that is merely "human" and a full-blown, sentient "person." Admittedly, abortion is despicable when used merely as an alternative form of birth control (instead of the pill or a condom), but it's a woman's right protected under the law.
