The aim of the leaflet is to draw the attention of parents to the book ON-LINE ZOO, which we offer for a free download both in the electronic text form and in the audio version. Especially during the Covid pandemic, the number of children who are active online is growing, as they spend more time at home than before and some even have distance learning there. The number of cases of cyberbullying and cybergrooming is constantly growing, so it is important that parents talk to their children about all possible risks in cyberspace and, if necessary, children were not afraid to turn to their parents as well.
