  • repo: https://github.com/lkosz/air_pollution
  • description: do we have a problem with air pollution? Of course we have, but are there placess free of it? And which are worst places to live? Popularity of this topic is because problem growth or maybe knowledge is growing? Does this discuss cause pollution reduction? Lockdowns in 2020 caused reduction of pollution? Etc.
