One letter in the collection was written by Kersti Kaljulaid, the current president of Estonia, who was a schoolgirl and the secretary of the Student Scientific Association at the time. The letter is one of the most restrained in the collection, as some of them are very emotional and even angry. In her two-page letter, Kaljulaid considers the potential dangers to the living environment. Unlike many other letters, Kaljulaid does not touch on the national question in her letter, although like some other writers, she demands a referendum on the plans for phosphorite mines.

The letter is handwritten, and has a few corrections, which means she probably did not write a draft. It was written on February 28, a few days after the relevant episode of the ‘Panda’ television programme.

It is interesting that Kaljulaid does not herself remember ever writing the letter, and assumes that it was the result of a recommendation by members of the Student Scientific Association.

The letter was published in the Estonian weekly newspaper Eesti Ekspress on 5 April 2017.
