    Iron is one of the most-used crafting materials in recipes. It is obtained by smelting iron ore in a heating device and is used to craft conveyors, gilded tools, industrial machines, and more. Iron can be obtained by smelting iron ore in a campfire, small furnace, desert furnace, or industrial smelter. Iron has a chance to be rewarded from opening Christmas presents. Iron can be turned into a

    The burning of coal, like the burning of all fossil fuels (oil and natural gas included), releases large quantities of carbon dioxide (CO 2) into the atmosphere and is a major driver of global warming.A potent greenhouse gas, CO 2 molecules allow the shorter-wavelength rays from the Sun to enter the atmosphere and strike Earth’s surface, but they do not allow much of the long-wave radiation
