i knew about Shakira and Dani environmental projects i just don't think that they are that ardant environment activists...
But i agree Rania is by far the oddest choice my guess they wanted someone from ME and she is the most known and glamorous
I agree, they are not hardcore environmental activits. But they have some ties and at least have some basic there, and definitely they can reach a different crowd (South America / youngsters). That is why they were picked imo.
Rania is almost "the pretty/glamorous" face there

Despite all, I think it is a quite impressive group and hopefully, they will be able to do good things for nature.
