I learned it nearly 30 years ago in school. I just did a search and found a link about it, though.
Also, seems that either I remembered wrongly, or my teacher made a mistake, but it seems it was most of the worlds coal; not oil, that came from all the piles of trees from that period.
Correct. In theory, we could make more oil in the lab. We cannot make more coal, because the wood will get broken down by bacteria far before it turns to peat, lignite, sub-bituminous, or bituminous coal, and much less anthracite.
