Paul and Clément have just launched a very important new service. It allows users to indicate, for each cave, the rules to follow to protect the environment: presence of bats, following a marked path, cave-specific rules, and wearing clean clothing. It is also possible to share information related to risks present in the cave: pollution, CO2, rockfalls, and flooding. Finally, it is possible to report tourist caves to offer access to the underground world to those unfamiliar with it. Do you know a particular area well? Would you be willing to provide this information about the caves you know and share your experience with these new features? Thank you for your help.
