Sustainable Management Of Rocks, Ores And Minerals
Muhtasari
Rocks, ores and minerals are finite: once a deposit is dug out, it is gone for good, because new rock forms far more slowly than we use it. With the world's population and appetite for metals still rising, this raises an uncomfortable question. How can we keep using materials that cannot be replaced without simply running out, and without wrecking the landscapes we mine?
This lesson looks at what sustainable management really means for non-renewable materials, and the practical strategies that make their use more sustainable: reducing and reusing, recycling, extracting more efficiently, finding substitute materials, and using laws to enforce all of these. You will also learn to weigh the benefits and limitations of each strategy, the kind of balanced judgement the exam rewards.
Malengo
- 1.3.1 Define a finite resource as a natural resource that is used up at a faster rate than it is replaced.
