The Faculty of Fisheries and Protection of Waters USB celebrated the World Water Day 2021 (22. 3. 2021) virtually, but actively. We registered the faculty for a seven-day virtual run for water. We ran together 250 km under the challenge: „Put on sneakers and run for water“. Employees, students and other supporters of our faculty took a part in this challenge and we had an opportunity to highlight global water problems on the faculty´s social networks. 134 countries took a part in the run for the World Water Day 2021 and we are glad that the main organizer of this event, marathonist Mina Guli, appreciated our enthusiasm.
