I had been hearing about this campaign to clean up Slovenia in one day, mostly from former students of mine. I thought it was an excellent idea and was very sad that I am no longer in Slovenia to participate in something so wonderful. The idea was inspired by a documentary about a similar campaign, which took place in Estonia in 2008. It was organised by the organisation "Ecology without Borders" and took place yesterday. The most inspiring part of it is that about 250,000 volunteers showed up, removing about 80,000 cubic metres of garbage!
Now, I wonder if it would be possible to organise something like this here in Jordan?
Here are some articles about the campaign:
