It's only economical if you ignore externalities, which is the point the cited sources are making - and on Wikipedia, we follow the cited sources. MrOllie (talk) 13:54, 9 June 2023 (UTC)[reply]
Although coal is known from most geologic periods, 90% of all coal beds were deposited in the Carboniferous and Permian periods, which represent just 2% of the Earth's geologic history."
so what
"Jet, a compact form of lignite, sometimes polished; used as an ornamental stone since the Upper Palaeolithic"
"ornaments" seem distracting
Fossils and amber may be found in coal.<ref>Poinar GO, Poinar R. (1995) ''The quest for life in amber''. Basic Books, {{ISBN|0-201-48928-7}}, p. 133</ref>
For a big article, these hobbyist details are distracting
when dead plant matter was protected from biodegradation and oxidation, usually by mud or acidic water" removed "biodegradaton".
This topic is vast and important. The article is too long. I will remove "Transition away from coal" since we have a article focused on that aspect: coal phase-out
Main recommendation:
1) An article about coal, period. What is it? Where did it come from? Many classifications (rank, grade). What is it used for?
2) The rest: mining (and economics), environmental impacts

Agree with the recommendations. Topics related to coal covered by other articles should only be mentioned briefly with a link Ita140188 (talk) 10:28, 7 August 2024 (UTC)[reply]
