Copper is a metal that is used for many purposes. It is mined from the earth using various methods. Though the amount of copper in the Earth's crust is very large, if the mining of copper continues, it will eventually run out. Students listed methods to help conserve the world's copper supply. Which method might actually increase copper mining instead? A a plan to collect copper bound for landfills and recycling it instead B the development of a cheaper and more efficient way to mine for copper C development of a material that could serve as a substitute for copper wiring D the use of other metals to replace the copper normally found in electric motors

Answer 1

The method that might actually increase copper mining instead is B: the development of a cheaper and more efficient way to mine for copper.

If mining becomes cheaper and more efficient, it could lead to an increase in the actual amount of copper mined, as it would encourage more mining activities and possibly lower the financial barriers to extracting copper from resources that were previously deemed unprofitable.
