The effects of Toxic wastes on Aquatic Animals
By observing the ocean, seas and bodies of water around us, we saw that many fish and aquatic animals were floating lifelessly in the waters. We have also watched news about fish kills. We want to know why and how. We want to save wild life. Seeing those dead aquatic animals, it’s such a waste of life. We want to know if toxic wastes from factories have anything to do with the death of aquatic animals. We also want to see if it will affect other species and when one is affected; it might spread quickly and cause an epidemic. When aquatic animals die, what will people eat if other animals were to be extinct too because of the epidemic that it will cause? Animals like cows, goats, and others will drink from the polluted waterways and they will be affected too. All others creatures will therefore be greatly affected. Maybe the main causes of the deaths are people’s activities like dynamite fishing, throwing of trash on bodies of water, oil spills from ships, and toxic chemicals from factories. Maybe the trash, oil spills and dirty toxic materials dumped in the water kills the sea creatures. Our objective is to know the effects of wastes to aquatic animals. We want to take part in saving the earth, in saving nature. The significance of this study is to save Mother Earth and to warn people that we should take action now! REVIEW OF RELATED LITERATURE
Moller (1997) studied the Nakhodka oil spill and suggested improvements with respect to shippers' perspective defining the role of industry in dealing with oil spill pollution. Dicks (1998) summarized impact of oil spills on different components of the marine environment as well as potential for natural recovery and manmade restoration/re-instatement measures envisaged according to international compensation conventions. Kerambrun and Parker (1998) dealt with shorelines inundated with thick black oil pollutants. Results of the study focus on the society to accept responsibility for repair of damage to environment through human intervention and carefully targeted clean-up activities. Wadsworth, Dicks & Lavigne (1999) stated that oil spills contaminate both agricultural facilities and livestock, which can be prevented by innumerable self-help response options like relocation of cages, transfer of stock and early harvest. He elucidated cooperation between ship owners, government and private bodies involved in addressing hassles due to oil spillage. Moller, Dicks, Whittle & Girin (1999) explored approaches for managing activity bans in fisheries and aquaculture sectors following oil spills. White (1999, 2000, 02) stated that considerable improvement is desired in spill response technology, highlighting technical and organizational problems associated with major marine oil spills. Also he reported that cost of incidence in coastal waters, shorelines and seas depends on factors like type of oil coupled with physical, biological and economic characteristics of spill locations, other factors being rate of spillage, weather, time of year and effectiveness of clean-up. Purnell (1999, 2002) examined costs associated with low technology shoreline clean-up methods that were used in response to Sea Empress incident. At the same time he categorized incidents according to their cause, type of ship, oil spilt and location. He also highlighted Amorgos incident in Taiwan. Dicks, Parker, Moller, Purnell & White (2000) examined a wide range of technical, organizational, logistic and financial problems faced by the people managing shoreline clean up operations due to oil spills around the world. Anderson (2001) sketched the characteristics of black oils that normally do not break down readily after spills and...
