S1·E58 What if nature had a price?

"Be careful! It's precious!" – we've probably all heard such warnings as children, for example, when we wanted to examine our father's camera or an old vase. That's how we learned to be careful with valuable objects. Curiously, nature is different. Even though it's the most precious thing we have, we humans don't treat it well. Not only do we use it, but we abuse it. Would it be different if nature and its services received some kind of price? If all of nature's free services were also made economically visible? For example, it provides us with food and drink, all kinds of important materials, cools us in the heat, purifies our drinking water and the air we breathe. In short: nature guarantees our survival.
