|Last supper? Plates of fish in La Nieves market. A recent study says that Colombia's marine fish populations are near collapse from overfishing.|
Scientists predict that global warm will eliminate Colombia's high-elevation wetlands within a few decades - which will cause wrenching changes in the nation's water supply.
|Abundance, but for how long?|
Marine ecology suffers from being out of more of most of our sight, and therefore out of mind. As long as the markets remain full of fish and shrimp, we assume there's abundance. But those fish may be coming from further and further away, out of increasingly scarce populations.
El Tiempo reports that Colombia harvests some 100 tons of marine resources each year - and that consumption will double in the next 20 years. Where will those fish and shrimp come from? Perhaps from fish farms. More importantly, we should ask where the fish the Chinese and Indians will eat will come from in 20 years.
