Happiness has everything to do with sustainability. People’s happiness relates to psychological well-being and health, living standards, good governance,ecological diversity and resilience, and so on. Both inhabitants and visitors may feel better when they feel appreciated, understand how they contribute to sustainability, are allowed to take active responsibility, and think that sustainability is organised and supported adequately. Think for example about the social isolation the countryside or an island can lead to. Especially young people can feel unhappy in such situations. Nevertheless bike lanes and nature areas ensure people have enough places for exercise and relaxation. In addition there is enough supply of healthy food. How would Texels system ensure that all (kind of) inhabitants and visitors are healthy and happy?
