Strange Days on Planet Earth – (Troubled Waters)Movie Notes21st Century Signals are around usMarsh in Wyoming - Leopard FrogsSt. Lawrence, Canada – Beluga WhalesColumbia, Missouri – HumansGeorgia, USA - HumansQueensland, Australia (Great Barrier Reef) – Crown of ThornsPacific Ocean - Mola MolaMarsh in WyomingBiologist Tyrone Hayes – Northern Leopard Frogs200 million years these frogs have flourishedFrogs are vanishing (20 species worldwide)Biometers – Frogs are telling us somethingLink: Farms Corn Production Chemicals Weed Killers = Atrozine (sprayed before planting)Hayes raised frogs with and without AtrozineFrogs in clean water were normalFrogs in Atrozine caused males to grow eggs in testes and even ovariesAtrozine can cause testosterone to convert into estrogen0.1 parts per billion causes deformities. Larger amounts don’t cause as many deformities. The immune system may detect these large amounts but the smaller amounts can slide under the radar.Risk Assessment – EPA says …need more information75,000 compounds Synergistic reactions SYNERGISM PRINCIPLESt. Lawrence, Canada (Marine Park)Synthetic chemical end up down the rivers, even in remote areasRobert Michaud is studying White Whales (Beluga)Canaries of the sea because of songIn trouble, highest rates of cancerThere are dozens of chemicals found in BelugasSome dead Belugas can be classified as hazardous wasteBelugas in captivity (aquariums) are used for comparisonMixtures of chemicals affect cells more when the immune system is compromisedStudied combinations of chemicals. An almost impossible task to study all the combinations of chemicals possibleWATER IS INTERCONNECTED !!!!!!!!!Columbia, MissouriEpidemiology – the study of the distribution and patterns of health-events in populationsShanna Swan – If it affects any animal, it affects usHigh rates of miscarriages from chlorine in our drinking waterMen – sperm compromisedWorst sperm quality in Missouri (not LA or NY where there is more air pollution)Due to farm chemicalsTap Water – chemicals are not removed during treatmentFood, cosmetics, farming all lead to exposure – reduce exposure. The amount is Key!!!Georgia, USADr. Richard Meagher – University of Georgia (Geneticist)Toxic mercury from industry is harmfulBacteria convert chemical mercury into toxic methyl mercuryMethyl Mercury builds up in the food chain to levels 10 million times greater than waterFerns take up arsenicAlpine plants take up ZincMustard plants take up LeadClovers take up Motor OilAdding a bacteria gene to plants can then take up methyl mercury and transform it into less harmful forms – Mercury stored in leaves or dispersed as vaporQueensland, AustraliaKatharina Fabricius – Associated Crown of Thorns (A type of Sea Star) explosion to NitrogenNitrogen used in agriculture – chemical runoff into the seaCauses issues with Blue Fin Tuna, Killer Whales and other marine organismsFertilizer (nitrogen) causes algal grown that allows the Sea Stars to thrive (at nitrogen hot spots)Vince Vitale – Farmer who planted trees to retard chemicals from moving into riversMost farmers remove almost all the trees near riversPacific OceanTierney Thys – Working with Mola Mola – Radio telemetry and trackingOccur in every tropical and subtropical areasConsidered an open ocean fishOnce thought open ocean fish were buffered from pollution issues (chemicals diluted)Tracking showed fish do come close to shoreWe can concentrate clean-up efforts by knowing where these animals travelAnimals are a window into out lives ................
