Before the midterms, President Trump tried to rally his base by stoking fear of a caravan of Central Americans heading toward the southern border – overlooking the fact that people often migrate together for safety. But even group travel couldn’t protect all caravan members. Two trucks carrying 80 migrants have gone missing in Mexico, “sold” to a band of armed men, according to one witness. Human rights scholar Luis Gómez Romero reports on the humanitarian crisis unfolding in Mexico, one of the world’s most violent places.
The point of having a World Toilet Day is to highlight the fact that safe sanitation remains a luxury. Billions of people don’t have access to a toilet. Part of the reason is that toilets are badly designed for regions like sub-Saharan Africa that are water scarce and have only limited plumbing and sewage facilities. But there are solutions. Mooyoung Han and Shervin Hashemi describe innovative designs that use no water and can transform waste into a valuable resource.
