In this nutty episode Hans Fritschi presents several edible seeds or nuts that grow at Discovery Garden Nong Khai. If one of them would be grown in a sustainable way, it could ease or even solve the problem of cow flatulence. As you might know, cows fart a lot and that is not good for mother earth. How can we make a tasty vegan chocolate mousse without any butter or cream? If we succeed in replacing those two elements, mankind can reduce the number of farting cows dramatically and thus maybe even save the planet. In an other major development host Hans Fritschi is able to present a positive aspect of the normally so deadly gravitation.
