Tiktok and the climate

A modern smartphone contains a large number of  elements (highlighted in color). Titanium, for example, is used in the manufacture of the SIM card (light blue), and cobalt in the manufacture of the battery (orange). Hydrogen, which is contained in the housing (yellow), was already used in phones of earlier generations (1960 and 1990). Other elements, such as helium, molybdenum and cadmium, which were used in the past, are no longer present in modern smartphones. (translated by DeepL.com)
