The document discusses the aftermath of the 2010 Haiti earthquake and subsequent challenges. It provides a timeline showing the earthquake killed 30,000, cholera outbreak in 2010 killed 8,000, and Hurricane Tomas in 2010 exacerbated problems. In 2013, disaster workers began leaving as cholera still lingered. The document calls for a concerted international effort to rebuild infrastructure, provide clean water, housing, and address Haiti's vulnerability to future natural disasters through engineering solutions.
