A brief definition of the term "pro-life": To be pro-life is to oppose the deliberate killing of innocent human beings, such as through abortion, infanticide, and euthanasia.

The Universal Declaration of Human Rights, adopted by the United Nations in 1948, declares in Article 3: "Everyone has the right to life, liberty and security of person."

The US Declaration of Independence states: ".... all .... are endowed by their Creator with certain unalienable Rights .... among these are Life ...."
