It doesn’t appear that the Catholic ban on birth control has much effect. The United Nations and Western aid agencies push their pro birth control, pro abortion agenda with every bit of financial bribery, coercion and control possible. The Catholic Church is the lone voice speaking a word of warning to the whole human race not to commit long term corporate suicide.
What is needed? The pope is right.
The problem is not too many people, but too many people in the wrong place and too many rich people hogging all the resources. The problem (for instance) is wealthy landowners in the developing world who push workers off the land, refuse to pay a living wage for farm workers who end up crowded in the slums of big cities.
The problem is not too many people. The problem is too many people who will not share and look after their brothers and sisters.
