Human population control is the practice of artificially altering the rate of growth of a human population. Historically, human population control has been implemented by limiting the population's birth rate, usually by government mandate, and has been undertaken as a response to factors including high or increasing levels of poverty, environmental concerns, religious reasons, and overpopulation. While population control can involve measures that improve people's lives by giving them greater control of their reproduction, some programs have exposed them to exploitation.
Worldwide, the population control movement was active throughout the 1960s and 1970s, driving many reproductive health and family planning programs. In the 1980s, tension grew between population control advocates and women's health activists who advanced women's reproductive rights as part of a human rights-based approach. Growing opposition to the narrow population control focus led to a significant change in population control policies in the early population control may use one or more of the following practices although there are other methods as well contraception, abstinence, medical abortion, emigration, decreasing immigration, sterilization, euthanasia, and genocide.
Contraception is a technique of birth control that can be classified by the stage of reproduction during which it is active. A form of birth control which prevents the sperm from fertilizing the egg is a contraceptive agent. A form of birth control which acts after fertilization to prevent or interrupt the implantation of the embryo into the uterine lining is a contraceptive agent. After implantation has occurred, an agent which ends gestation by terminating the pregnancy is an abortifacient. These mechanisms of action are not always mutually exclusive. One substance or device can have more than one potential effect depending upon when it is used. For example, while mifepristone is best known as an abortifacient, it can also function as a contraceptive agent. Likewise, the IUD can be used as a contraceptive depending upon when it is inserted. Abstinence is not having sex. A person who decides to practice abstinence has decided not to have sex. If two people don't have sex, then sperm can't fertilize an egg and there's no possibility of a pregnancy. Some forms of birth control depend on barriers that prevent the sperm from reaching the egg (such as condoms or diaphragms). Others interfere with the menstrual cycle (as birth control pills do). With abstinence, no barriers or pills are necessary because the person is not having sex. You don't have to be a virgin to practice abstinence. Sometimes people who have been having sex decide not to continue having sex. Even if a person has been having sex, he or she can still choose abstinence to prevent pregnancy and sexually transmitted diseases (STDs) in the future. Abstinence is 100% effective in preventing pregnancy. Although many birth control methods can have high rates of success if used properly, they can fail occasionally. Practicing abstinence ensures that a girl won't become pregnant because there's no opportunity for sperm to fertilize an egg. A medical abortion is a type of non-surgical abortion in which abortifacient pharmaceutical drugs are used to induce abortion. An oral preparation for medical abortion is commonly referred to as an abortion pill.
Medical abortion became an alternative method of abortion with the availability of prostaglandin analogs in the early 1970s and the antiprogestogen mifepristone in the 1980s. Emigration is the act of leaving one's country or region to settle in another country. It is the same as immigration except from a different perspective. Human movement in general is termed migration. There are many reasons why people might choose to emigrate. Some are for reasons of religious, political or economic freedom or escape. Others have personal reasons such as marriage. Some people living in...
