Nate you clearly do not understand the interdependency of life in the sea. Dredging causes excessive turbidity which by the report can have long term effects that may or may not be recoverable. One significant effect in the report is decreased photosynthesis...how do you think seagrasses survive? Seagrass beds harbor life that feeds other life that feed the reef.
One fact is for sure...if the reef environment dies, so does tourism in Belize. Without that there will be no need for the beaches, ports, roads and other infrastructure being created by dredging. Nature can heal itself but when man disrupts the cycle the results can be devastating and irreversible.
A mountain of sand the size removed by the dredging clearly caused significant disturbance in the sea, the consequences of which have not been fully realized yet. STOP THE MADNESS.
