RIO DE JANEIRO, BRAZIL - MARCH 08: A supporter of legalizing abortion poses during a march for women's rights on International Women's Day on March 8, 2016 in Rio de Janeiro, Brazil. Marchers called for myriad reforms including protection from male violence, health care and expanded female reproductive rights. Women's reproductive rights have taken on a new focus in Brazil following the onset of the Zika virus outbreak, which authorities strongly suspect is linked to birth defects. Brazilian law currently only allows abortion in cases of rape or certain dire health threats which currently do not include the Zika virus. (Photo by Mario Tama/Getty Images)
