Calcium and magnesium, the causes of scale and scum from hard water, are referred to as ions, and as water passes through the resin the calcium and magnesium ions swap places with the sodium ions on the resin. Of this vast volume of water, NOAA’s National Geophysical Data Center estimates that 321,003,271 cubic miles is in the ocean. In 1999, the National Oceanic and Atmospheric Administration (NOAA) officially recognized the Southern Ocean as a separate body of water, but it took until 2021 for the IHO and the National Geographic Society to recognize it as separate from the Pacific Ocean.

In 1880, meteorologist Rollo Russell wrote an influential pamphlet, London Fogs, noting that “numerous deaths occur in the course of the year from smoke-fogs, not unusually thick, producing or increasing diseases of the lungs”. London had seen a succession of acts and rules over the centuries to improve its air-such as the Smoke Nuisance Abatement (Metropolis) Act 1853 and 1856 and the Public Health (London) Act 1891. However, despite the link between air pollution and health being well understood by the late 19th century, such efforts had not proven to be effective public health measures. Therefore, air pollution was not being reduced so much as transferred from the area of consumption to the area of production.
