Nicolas Thun works for the Albert Schweitzer Stiftung in Berlin, Germany. Over the past five years, he has spent over 2500 hours doing street campaigning. As a great eyecatcher, the Albert Schweitzer Stiftung uses a giant pig mobile promoting the vegan lifestyle, called the GrunzMobil. Activists oft the Albert Schweitzer Stiftung reach out to people primarily to sign up for the Vegan Taste Week, a vegan starter kit. You can learn more about the campaign here and media coverage here. Nicolas has also given many theoretical and practical coachings for volunteers about improving their appearance and communication.
