Sanitation and open defecation, of course, are sensitive topics. They’re things most people don't want to talk about, let alone let someone document them. And this is the reason the problem is so big. No one talks about it.
An Uncomfortable Word: Sanitation
In our overpopulated world, poor sanitation contaminates water and food supplies, making it one of the deadliest issues that humans face. But words like open defecation – which exposes women and girls to the risk of rape – and faeces are uncomfortable words, making sanitation an issue that politicians will rarely champion. India is trying to change that, following in the footsteps of Vietnam, to change the health of their workforce and children.
