The streets of cities across Latin America were bathed in green Thursday as tens of thousands of women marched to commemorate International Safe Abortion Day.

Latin American feminists have spent decades fighting to roll back strict prohibitions, although there are still few countries with a total ban, like El Salvador and Dominican Republic.

In Mexico, marchers celebrated the recent decision by Mexico’s Supreme Court to decriminalize abortions at the federal level. In Argentina, marchers had a more somber tone, worrying that the strength of a populist far-right presidential candidate going into elections in October could signal peril after years of work by feminists.

Abortion was the heart of the protests, but crowds of women also raised alarm about the region’s high rates of gender-based violence as well as abuses aimed at LGBTQ+ communities.
