Main Body

5Release of Radioactive Waste: Has recently alleged by China & S Korea. Release of water ahead in Fukushima raising early concern. 6) Degradation of Mangroves: Mangroves act as natural filter for direction off by these protect marine ecosystem, but due continued degradation of mangrove → leads to marine pollution. 7) Spread of invasive species: due to transboundary shipment many new invasive species are introduced at various location → thus endangering the local species, eg: zebra mussel. 8) Increasing level of atmospheric carbon dioxide - leads to acidification of ocean waters → warming → ocean warming → damages biodiversity, coral bleaching. 9) Melting of glaciers due to global warming: Introduction of zombie virus → leads to threat to marine ecosystem, human based past → harming based past. 10) Overexploitation of fisheries: physical degradation of marine ecosystem.

Overall Impact of Marine pollution: → Heating of Ocean → overall heat content of ocean increases accelerated climate change and degraded biodiversity → More frequent cyclones & tsunamis → ingested by marine animals → loss of biodiversity, biomagnitication. → Thus it is high time to take decision steps to prevent further damage of protected the ocean.

You are a no-nonsense, honest officer. You have been transferred to a remote district to head a department that is notorious for its inefficiency and callousness. You find that the main cause of the poor state of affairs is the indiscipline of a section of employees. They do not work themselves and also disrupt the workings of others. You first warned the troublemakers to mend their ways or else face disciplinary action. When the warning had little effect, you issued a show cause notice to the ringleaders. As a retaliatory measure, these troublemakers instigated a woman employee amongst them to file a complaint of sexual harassment against you with the Women’s Commission. The Commission promptly seeks your explanation. The matter is also publicized in the media to embarrass you further. Some of the options to handle this situation could be as follows: (i) Give your explanation to the Commission and go soft on the disciplinary action. (ii) Ignore the commission and proceed firmly with the disciplinary action. (iii) Brief your higher-ups, seek directions from them and act accordingly. Suggest any other possible option(s). Evaluate all of them and suggest the best course of action, giving your reasons for it.
