Florida Keys threatened by sewage
The Florida Keys, one of the most treasured ecosystems in the US, is being destroyed by sewage. In some areas, near-shore tropical waters have changed to the colour of pea soup. Scientists warn against swimming in canals that have become long fingers of stagnant water. With 80,000 permanent residents throughout the Keys and 2 million tourists each year, the surrounding marine environment is being stressed beyond its limits. Some scientists warn that as near-shore water quality continues to decline, the region's ocean reefs will also decline.
