a way to terminate a human being's life.
The joining of a man's sperm with a woman's egg, a zygote is formed, thus, the very first stage of a human being's life. All information is present at this stage for the human person to grow into an embryo, fetus, infant, toddler, child, teenager, and adult. There are not separate distinctions of the human species during its first stages of growth.
A rose's seed can only be a rose. That seed cannot be a fruit, vegetable, animal, or a human being. The rose's seed is the first stage of its life, although it doesn't look like a rose, all the information is contained within that seed for it to look like a rose. You cannot separate these into different species, because they are the same. From the moment of conception, the human life should be protected. The dead are buried and their wills are respected. Once a human life is created, there is no turning back. There is nothing in our power to make it un-human. Therefore, abortion is one way to terminate a human being's life.
