Conflict, repression, economic circumstances, drought, and famine have driven the migration of nearly 2 million people from Sub-Saharan Africa and the Middle East to Southern Europe in the last decade.

Migrants all over the world have died and gone missing at alarming rates. In the past decade, this endless tragedy has plagued the Mediterranean Sea in particular. Since 2014, over 25,000 migrants have gone missing and presumably died while taking the perilous journey asea.

Aid groups like who have been giving life-saving assistance to migrants who cross are now being criminalized. Twenty-four aid workers in Greece stand trial for helping migrants who were crossing through the Mediterranean.

We speak with New Yorker staff writer Alexis Okeowo who covers conflict, culture, and human rights across Africa, Mexico, and the American South to better understand the scale and impact of this crisis and what can be done to improve migration conditions.
