IB ESS EXAM FULL REVIEW QUESTIONS WITH 100% VERIFIED CORRECT ANSWERS LATEST UPDATE List and explain a historical event or influence that had an impact on the development of the modern environmental movement. (1) - Correct Answer Ex: Minimata, Japan In 1956, a chemical company in Minimata Bay released toxic methyl mercury into the waste water. As a result, organisms in the water like fish and shellfish were poisoned due to the contamination. Local people who consumed these fish developed mercury poisoning. This raised awareness about the threat of industrialization and the negative consequences associated with pollution in the environment due to poor and mismanaged industrial activity. Anti-pollution measures and the development of new policies and technologies to prevent this event from happening again were also promoted. (UN treaty, Minimata Convention on Mercruty) Minimata disease still exists today and remains a health concern for the people of japan. List and explain a historical event or influence that had an impact on the development of the modern environmental movement. (2) - Correct Answer Ex: Rachel Carson's "Silent Spring" In 1962, Carson published a book discussing the aftermath of WWII and the devastating affects on the environment from a pesticide that was commonly used during the war, called DDT. This book raised awareness about DDT, which was used for agricultural and commercial purposes prominently during WWII. This pesticide threatened organisms as the food chain progressed as this pesticide would bioaccumulate in organisms (one organism would consume DDT, and the next organism to consume the poisoned one would thus possess a larger amount of DDT). This led to reduced population sizes, especially in higher trophic levels, and eventually, DDT was banned in the US. List and explain a historical event or influence that had an impact on the development of the modern environmental movement. (3) - Correct Answer Ex: Bhopal, India In 1984, an explosion at a U.S owned Union Carbide plant released 42 tonnes of toxic methyl isocyanate gas. Between 8,000 and 10,000 people died as a result within the first two days. This tragic event highlighted the importance of safety protocols and procedures in factories, as well as the emphasis of better international management(as this plant was owned by the U.S). Due to a lack of supervision, amateur workers were hired without the proper training needed to operate machinery, and thus gas was leaked as a result of a factory malfunction. List some ways in which attitudes towards the environment can change over time? - Correct Answer - when a new resource or product is first developed, people are more likely to see benefits than potential problems - key events prompt change
