Special Nature Reserve Kraljevac in partnership with the Deliblato’s  Paja Marganović Primary School participated in a global action of the World Wide Fund For Nature (WWF) “Earth Hour” on March 19, 2016. The action’s main aim was to draw attention to climate change impacts and ways we can help planet Earth by changing our everyday life and energy consumption. For the first time, around 100 students with their parents participated in turning out lights for one hour at the Paja Marganović Primary School, followed by an acoustic concert of Romanian traditional music by candlelight and releasing sky lanterns with best wishes for planet Earth into the night sky.
