Just because Abortion is illegal does not make it go away. If outlawing abortion worked then we would not see these statistics:
"Experts say the Dominican Republic has one of the region's highest abortion rates, and also a high number of women hospitalized after illegal abortions. According to the Alan Guttmacher Institute in New York, a group that conducts sexual and reproductive health research and policy analysis, a survey conducted in the early 1990s showed 82,000 illegal abortions a year in the Dominican Republic.
The Dominican Republic's rate of 44 abortions per 1,000 women is more than double the rate in the United States, where abortion is legal on demand, according to the Alan Guttmacher Institute.
Despite having some of the strictest anti-abortion laws in the world, Latin America has the second highest rate of terminated pregnancies in the world, according to U.N. figures. Only Eastern Europe's is higher than this region's rate of 37 per 1,000 women of childbearing age. The U.N. figures estimate that 4 million abortions take place in Latin America annually - and 5,000 women die each year from complications."
To quote Bill Clinton, "abortion should be safe, legal, and rare." I believe that if we want to reduce abortion in America we keep it safe and legal. To make it rare we need to have a well educated population, on how to prevent pregnancy. We need to make sure poor people can afford to care for their children. The biggest statistical correlation to high abortion rates is poverty, not legality.
