The Vatican and family planning
This spring the Vatican has started a campaign to propagate its viewpoint on birth control. Thus it takes an overt stand against the 1974 World Population year, proclaimed by the UN. According to The Times newspaper in London the Vatican resists all efforts to develop a system of world population control. It rejects contraceptives, sterilisation and abortion.
In view of this startling campaign I cannot but repeat the statement I gave at the Brussels meeting with the Vatican Secretariat for Unbelievers on October 1,2 and 3, 1970: "The official Catholic policy influences through Catholic political power to a high degree the policy of nations even if the Catholics represent a minority of the population.
And by this effect the leading circles of the Roman Catholic church take a tremendous responsibility for the future of mankind. Poverty, lack of medical and educational services, pollution, starvation, conflict and war are aggravated by excessive increase of population. So the attitude of the official leadership of the Roman Catholic church regarding voluntary contraception, family planning and population control leads to appalling social consequences".
Son once more in history religious dogmatism leads to immoral activities. Humanists cannot but oppose this policy, supporting this UN effort towards population control to the benefit of human beings.
Statement by Prof. Dr. J.P. van Praag, 1974

Church and Birth Control
Vatican opposes birth control though it has no solutions to the problems caused by overpopulation, problems such as degradation of nature, hunger, illiteracy and violence. According to the Vatican man has no right to interfere with life and birth control amounts to taking life. Life and death are two sides of the same coin. If we have no right to interfere with life we have no right to interfere with death. But we have systematically interfered with death using modern medicine and the church can proudly claim that it has contributed to universal health care. This deferment of natural death from diseases, epidemics and accidents is the main reason for today’s population explosion. Modern medicine’s systematic interference with death makes it imperative that it interferes with life also. The Church too has no choice in the matter. Either refrain from interfering with death using modern medicines and health-care, which is not feasible, or interfere with life using birth control. You cannot interfere with death without interfering with its complementary side - life
Contraceptives
I consider to rejects contraceptives is wrong. Vatican just still conservative.
