Cooking is done with coal.
Steam engines, steamers, heating furnaces in factories and work-shops require coal for steam.
Metal ores cannot be purified from the dross without the heat produced from coal.
Iron cannot be melted and made into various tools, machinery and weapons.
Coat-tar, coal-gas and many other such things cater for our necessities and comforts. Coal-tar preserves wood and iron from destruction.
Coal-gas lights houses and streets.
Various chemicals like dyes, medicine, and sweet scent are made of coal. Science and civilization owe much to coal.
