Farming Salmon Contaminating Ecosystems
series: Global 3000
air date: 12/01/13 6:00 AM
Aquaculture in Canada - The Problem with Farmed Salmon: Aquaculture-grown fish and seafood is becoming increasingly common. Worldwide, more fish than cattle are farmed. But the booming fish industry is causing environmental problems. Medications, pesticides and parasites are escaping from open-water farms and contaminating the ecosystem. Scientists and environmental activists are sounding the alarm for the unique, UNESCO-protected ecosystem of Vancouver Island, which contains one of the world largest concentrations of wild salmon. Ecology versus Economic Use - The Clean Water Quarrel: Germany's Federal Environment Agency estimates that a quarter of all German groundwater contains excessive concentrations of nitrates - threatening some communities' water supply. The cause is over-fertilization of farmers' fields. Germany, Austria and Switzerland have been successfully joint-monitoring Lake Constance water quality for years. But authorities in Lower Saxony are only beginning to tackle the problem. Drinking water there often exceeds the EU norm of 50 milligrams of nitrates per liter. Global Snack: Blini from Ukraine - Ukrainian blini are made with whey and buckwheat flour, and the classic variety is filled with egg, pancetta and sour cream. But the Blin-Clin-Ton kiosk in Kiev offers 20 additional types. Rash of Suicides in India - Cotton Farmers without Hope: Many Indian cotton farmers are being driven to despair by crippling debts. An estimated 200,000 of them have taken their own lives in the past few decades. Many went deep into the hock to buy genetically modified cottonseed, which they hoped would improve yields. But GM crops require ideal conditions. The rash of suicides reflects the inequality of opportunity within global capitalism - big multi-national corporations make all the profit while small farmers can no longer survive.
