Labor Camps essays

Russian Prisons/Labor Camps essays Russian Prison/Labor Camps Following the Bolshevik takeover of the Russian Revolution in 1917, the Soviets dismantled the broad spy networks of the czarist secret police, the Okhrana, but the new government kept all essential functions of that organization in place, replacing the czarists with Bolsheviks and changing the name to Cheka. The official name of the organization was the Extraordinary Commission for Combating Counter-Revolution, Sabotage and Criminal Offenses by Officials. The Russian people suffered as much under the oppressive Cheka as it had from the brutal Okhrana. The Cheka's main objective was to track down and liquidate all those who opposed Vladimir Lenin and the Communist state. In many respects, the Cheka proved to be even more terrible than the Okhrana. Its first director, Felix Dzerzhinsky, one of Joseph Stalin's closest allies, was utterly ruthless, a spymaster who unflinchingly ordered assassinations and mass murders. The Soviet system of forced labor camps was first established in 1919 under the Cheka. It was not until the early 1930s that the camp population reached significant numbers. By 1934 the GULAG, or Main Directorate for Corrective Labor Camps had several million inmates. Prisoners included murderers, thieves, and other common criminalsalong with political and religious dissenters. The GULAG, whose camps were located mainly in remote regions of Siberia and the Far North, made significant contributions to the Soviet economy in the period of Joseph Stalin. GULAG prisoners constructed the White Sea-Baltic Canal, the Moscow-Volga Canal, the Baikal-Amur main railroad line, numerous hydroelectric stations, and strategic roads and industrial enterprises in remote regions. GULAG manpower was also used for much of the country's lumbering and for the mining of coal, copper, and gold. Secret Police like the KGB and other factions helped to keep a tight grip on Russias lab...

Microplastics and Their Environmental Effects

Microplastics and Their Environmental Effects Microplastics are small fragments of plastic material, generally defined as smaller than what can be seen by the naked eye.  Our increased reliance on plastics for countless applications has negative consequences to the environment. For example, the plastic manufacturing process is associated with air pollution, and volatile organic compounds released over the life of the plastic have deleterious health effects for humans. Plastic waste takes up significant space in landfills. However, microplastics in the aquatic environment  has been a newly emerging concern in the public consciousness. As the name implies, microplastics are very small, generally too small to see although some scientists include pieces up to 5mm in diameter (about a fifth of an inch). They are of various types, including polyethylene (e.g., plastic bags, bottles), polystyrene (e.g., food containers), nylon, or PVC. These plastic items become degraded by heat, UV light, oxidation, mechanical action, and biodegradation by living organisms like bacteria. These processes yield increasingly small particles that eventually can be classified as microplastics. Microplastics On the Beach   It appears that the beach environment, with its abundant sunlight and very high temperatures at ground level, is where the degradation processes operate fastest. On the hot sand surface, plastic trash fades, becomes brittle, then cracks and breaks down. High tides and wind pick up the tiny plastic particles and eventually add them to the growing great garbage patches found in the oceans. Since beach pollution is a major contributor of microplastic pollution, beach cleanup efforts turn out to be much more than esthetic exercises.   Environmental Effects of Microplastics Many persistent organic pollutants (for example, pesticides, PCBs, DDT, and dioxins) float around the oceans at low concentrations, but their hydrophobic nature concentrates them on the surface of plastic particles. Marine animals mistakenly feed on the microplastics, and at the same time ingest the toxic pollutants. The chemicals accumulate in the animal tissues and then increase in concentration as the pollutants are transferred up the food chain.As the plastics degrade and become brittle, they leach out monomers like BPA which can then be absorbed by marine life, with relatively little known consequences.Besides the associated chemical loads, ingested plastic materials can be damaging for marine organisms, as they can lead to digestive blockage or internal damage from abrasion. There is still much research needed to properly evaluate this issue.Being so numerous, microplastics provide abundant surfaces for small organisms to attach. This dramatic increase in colonization opportuni ties can have population-level consequences. In addition, these plastics are essentially rafts for organisms to travel further than they usually would, making them vectors for spreading invasive marine species. Microbeads A more recent source of trash in the oceans is the tiny polyethylene spheres, or microbeads, increasingly found in many consumer products. These microplastics do not come from the breakdown of larger pieces of plastic but instead are engineered additives to cosmetics and personal care products. They are most often used in skin care products and toothpaste and wash down drains, pass through water treatment plants, and end up in freshwater and marine environments. There is increased pressure for countries and states to regulate microbead use, and many large personal care product companies have pledged to find other alternatives. Sources Andrady, A. 2011.
