Pollution rife during UN environmental conference in Brazil
The throngs streaming into Rio for a sustainable development conference may be dreaming of white-sand beaches and clear, blue waters. What they are first likely to notice as they leave the airport, however, is not the salty tang of ocean in the breeze, but the stench of raw sewage. That’s because the airport sits by a bay that absorbs about 320 million gallons of raw waste water a day: 480 Olympic swimming pools worth of filth. The welcome here is a rank reminder of just how hard it will be to balance economic growth and environmental protection.
