Nicaragua says a $50 billion interoceanic canal would give the country the economic boost it needs to escape grinding poverty. But environmentalists and scientists say the project is poorly planned.
Water issues affect us all, from the women who spend hours a day fetching water to political battles over international rivers to melting icepack and rising sea levels. We are all downstream.
Worldwide, just under 900 million people lack reliable access to safe water that is free from disease and industrial waste. And 40 percent do not have access to adequate sanitation facilities. The result is one of the world's greatest public health crises: 4,500 children die every day from waterborne diseases, more than from HIV-AIDS, malaria, and tuberculosis combined.
A robust economy depends on water. So does a thriving ecosystem. Enter politics, fulcrum of the water issue, weighing the fate of economies against the health of individuals and of the environment as a whole. Balance has been elusive. One fifth of the world's population lives in areas where water is physically scarce, and a quarter of the population faces shortages due to lack of infrastructure.
