It might seem strange to say that the deep sea, the vast expanse of the world’s oceans beyond the continental shelf, is at risk of conflict and competition.

The fetal brain defects known to be linked to the virus are devastating – and may only be the tip of the iceberg in terms of the virus’s impact, according to a panel of high level U.S. government officials speaking at the Wilson Center on May 24.

At USAID we recognize the threat poor sanitation combined with rapid urbanization presents to human health, dignity, and prosperity. This is why we have made urban sanitation a global priority for the Agency. During a recent visit to India, I was able to see some of the work being done to bring sanitation services to urban areas, and had the good fortune to meet some inspiring women who are advancing these efforts in their communities.
