Quizplus · Accepted Answer

Extracting gold from stream sediments using mercury is a commonly used method for gold mining in Borneo. This method releases large amounts of mercury into the environment, causing severe pollution and toxicity in aquatic ecosystems. As a result, fish populations have dropped by 70% in the affected area. The other options (A, B, C, and D) are also associated with mining activities but are not specifically linked to the decline in fish populations in Borneo as stated in the question.
