A LinkedIn user named, Andrea Göhler wrote, “I just listened to an impressive interview with Christian Kroll, the founder of the sustainable search engine Apart from the fact that he did not sell his enterprise when it became profitable but gave it away, some of his final sentences in this interview caught extra attention: planting 1 trillion trees (as in 1 with 12 Zeros…) would offset part of the damage that has been done to our planet. And the cost would be about 1(!) % of the annual global military expenses. Globally we have the space for those trees, and we have the money, and we have the kids telling us not to mess up the planet- but we don’t do it?! How can that be?? Anyway, Christian Kroll, this is your billboard on Berlins Alexanderplatz?:”
