- Its a close call, Milk being an extract and since cheesemaking only has the one reaction, one building, and one product I think it should count as a extract (like thread being turned into cloth as part of textiles) --Antropax 17:02, 12 July 2012 (UTC)
There seems to be some debate on where the extract industry belongs. Agreed they do not belong in the Tertiary sector, but extracts are more of a chemical bottling industry. Where the primary meat industry provides a carcass, the extracts industry provides the processed bottled blood. --Antropax 07:20, 13 July 2012 (UTC)
Is trade really an industry as such. It is not a service nor does it create anything. Trade stands as a concept on par with industry, not a sector of it. --Antropax 07:29, 13 July 2012 (UTC)
28 February 2012 user:King Mir added construction industry, and the same day user:Nahno undid it stating 'That is not an industry as such'
