How this list was compiled

Written for this site; nothing was copied from another list. Questions and wrong choices are our own. Each explanation restates, in our own sentences, a fact from the English Wikipedia article named and linked beside the question (https://en.wikipedia.org, text under the Creative Commons Attribution-ShareAlike 4.0 license): Nature and Wilderness. The text of each article was fetched on October 2, 2026, and on October 3, 2026 the passage that states each fact was read in it before the question was kept. Left out on purpose: counts that change (species identified, wilderness areas registered, shares of land and sea still wild), forecasts of extinction, and the plain facts the site's science packs already ask. Levels are our estimate: easy is fair for any table, medium suits people who know the subject, hard will stump most tables. Each question also carries the date its article was read (checkedOn).
