This video on popular biology is one of 33 videos in 33 languages that I started making in July 2022 and will finish in 2023. I make all of my polyglot (multilingual) videos by myself, using only machine translators and my own experience with those languages, without any help from other people. I am also currently working on a set of polyglot (multilingual) videos in 33 languages describing the principles of my method of learning foreign languages.
