Argentina’s Senate will decide next week whether to give final approval to a government-backed bill that would expand the availability of legal abortion, a proposal that has divided a society with strong ties to the Roman Catholic church. On Dec. 11, the lower house of Congress approved the measure, which would allow interruption of pregnancies until the fourteenth week. The Senate vote is expected to be close. “We have the right to be able to decide about our own lives, about whether we want to have children and, if we want to have them, how many we want to have. If we decide to interrupt the pregnancy, we have the right to do it autonomously and freely,” Yamila Picasso, a 33-year-old activist, told Reuters outside Congress, where she was demonstrating. Picasso is a member of the National Campaign for the Right to Legal, Safe and Free Abortion, which has been demanding the new law for years. On the other side of the debate is Ana Marmora, a 29-year-old lawyer and journalist who is a spokeswoman for the Young Front, a group that rejects the legalization of abortion. She told Reuters in an interview at the group’s Buenos Aires headquarters that backers of the bill want women to be able to terminate pregnancies not out of need but simple desire. “Is it right that we discard our children just because we feel like it?” Marmora said.
