However, the percentage of the price of batteries in comparison to the overall cost of electric vehicles is predicted to continue its decline, in line with the development of battery technology and the increase in production. [...] The vertical movement of the thermocline is more affected due to the interannual ocean-atmosphere interactions that affect Indonesian waters, such as the El Niño–Southern Oscillation (ENSO) in the tropical Pacific Ocean.93 One of its results is the movement of warm or cold water from the eastern waters of the tropical Pacific Ocean near the western coast of South America, to the western waters nea. [...] Metal content in the bodies of biota (the flora and fauna of a region) varies for each level of the food chain (trophic level).98 Metal concentration is also influenced more by the physiology of the organism and the biological role of the metal than by trophic level.99 The lack of specific knowledge in each species regarding the rate and process of metal accumulation means that there is still unce. [...] In benthic fauna (marine organisms that live on the seabed), the thick depositing of large amounts of tailings sediment can cause the so-called ‘dead zone’ around the discharge point, the disappearance of species, changes in community composition and structure, changes in population and biomass abundance, and other problems.100 In a longer timescale, the composition and structure of the marine bio. [...] The study at the Lihir and Misima DSTD sites in Papua New Guinea found that the area around the tailings disposal had a much smaller benthic abundance than the area on the opposite side of the island.103 The taxonomic diagram of marine life around the discharge area is also significantly affected.
