Flying is cheaper than driving a car, but a disaster for the environment. Yet few politicians dare to levy excise duty on kerosene. This is only one example from a world where emotions and yelling are burying facts, and in which scientists lose connection with society. Why is that healthy and nice living environment still so far away, while everyone seems to want it? Read the interview with symposium organiser René Kleijn about how scientists can convince people to make sustainable decisions.
