Thames today is among one of the cleanest rivers across the globe and the question interrogates the impact of dumping wastes into it which would most likely be the pollution of water.<em> If people begin throwing the household waste into the river, it would lead to excessive water pollution again as it happened during 1830-60 when it became so polluted due to industrial and economic waste that it was affirmed to be dead biologically.</em> Around 10,000 people died due to water-borne disease Cholera as a consequence of the pollution of river Thames. Thus, if the people begin dumping again, it may lead to a situation worse than the previous spread of lethal diseases.
