Document Summary
Combines hydrological cycle with the problem of acid rain video aid used: downwind, downstream. Video: talks about the impacts of acid rain on areas where mining has decreased the ability of the surface and groundwater to buffer resulted in disrupting upland force ecosystems by damaging trees. Ecosystem approach emphasized that decisions made in one area affect all others (consider ecosystem processes and conditions such as disturbances, stability, complexity and diversity) Almost every material thing in modern society is either a direct mineral product or the result of processing with the aid of mineral derivatives such as steel, energy or fertilizers" (see middleton, 1999). Mining and pollution: mining sector vs. related environmental impacts: a lot of extracted materials that are not useful, therefore this waste or tailings, become a serious environmental issue by pollution waters and soil. Four main groups of materials in mining sector: Industrial minerals (e. g: lime, soda ash: metals (e. g: aluminum, copper, iron)
