Kidsleepy already mentioned this in the rant "Can we stop with the coronavirus ads already?", but it needs its own mention so creatives won't miss this opportunity.
The UN has released six creative briefs for anyone to take a stab at. You can find it all here in their global call for creatives.
This is your chance to show the world that you are a master communicator with great ideas, you will submit your results here, and if your ideas and campaigns are selected the UN will use them in future communications. This is basically the biggest pro-bono brief of a lifetime. Go forth and create, my friends.
