I want to know the answer to the following question:
How much of mined cooper has been extracted in the last 24 years?
All the background I'm provided with is that "As with many natural resources, the total amount of copper on Earth is vast (around 1014 tons just in the top kilometer of Earth's crust, or about 5 million years' worth at the current rate of extraction).". Is that enough to answer the question?
Answer: no
