Az élet láncolatai (E24)

Peter is going for a walk with his grandfather. Meanwhile, the latter explains to Peter that the sun is the source of all life and that if it wasn’t for the sun, our planet earth would be a cold and boring planet and there would be no life. That’s because the sun makes everything grow, as for example grains and fruits and trees, which then produce the oxygen that is vital for us to breathe. Peter learns about the food chain of nature, which means that there is a constant eating and being eaten by other creatures. The only exception is us, human beings, because we aren’t eaten by anyone. We still need food though, for the composition of our bodies, to produce energy and to stay alive. Unfortunately, many people eat way too much, with too much sugar and fat and then there’s trouble with their bodies. (iTunes)
