Page numbers usually have nothing to do with the content. But in physicist Mike Berners-Lee’s book, they show – albeit indirectly – the consumption of carbon dioxide2 employment. On page 25 he started with 0.2 grams for a pint (about 473 milliliters) full of tap water, on page 56 there is already more than 300 grams for three minutes of showering, and on page 137 there is a barrel for an artificial hip joint. Until the author concludes on page 177 with the massive figure of three billion for the “military footprint”.
Climate balance from cats to knee surgery
Berners-Lee has seasons where CO is for different things2Depreciation is estimated and arranged according to values. You start with “less than 10 grams,” followed by “10 to 100 grams” and so on, until you reach a billion tons of wildfires, soot, and wars.
Whether it’s drinks, animals, email, a new bedroom or flights into space – it’s fun to see if a text or message causes more greenhouse gases or how much a goldfish, Doberman and rabbit are consuming by comparison. Was it still about CO2– Surprised by the contribution of 0.2 grams of tap water, it’s actually about 400 grams per liter of bottled water. At the beginning of each section, Berners-Lee lists numbers from a similar category, such as domestic beer, domestic bottled beer or imported bottled beer. Then it explains in an understandable way how to calculate the values and gives all relevant sources.
The banana named after him appears relatively early, 110 grams per piece is not as bad as the author wrote. It grows under natural light, has a long shelf life and uses very little enclosure. An apple can actually cause more greenhouse gases and easily triple if not harvested from its own tree or locally and seasonally. Because when an apple is imported out of season, refrigeration and storage are also included in the balance sheet in addition to air transportation.
