Drawing contest for the children of staff members of the Federal Public Service of Public Health, Food Chain Safety and Environment:
Belgium - 2020
The Belgian NPPO promoted Beastie among the children of staff members at home at that time, because of the lock-down period due to COVID-19 . We invited the children to colour in a Beastie drawing or to draw plants or insects of their choice. Each participant has received a prize (a small bag of seed).
