Coca Shrimpola

Scientists have surprisingly found that many of the freshwater 'shrimps' (Gammarids) taken from waters in rural Suffolk contain drugs including cocaine and ketamine (https://www.theguardian.com/environment/2019/may/02/shrimp-cocaine-found-in-all-tested-in-rural-county-suffolk). The results are seem odd because rural areas are not regarded as hot beds of drug usage in the ways that urban localities like Birmingham, London and Manchester are. It's another indication, however, of how human activities influence the animals around us in unpredictable ways.
