How big is our ecological rucksack? What can we do to change that? Can we cover the spreading gap?
Dennis Meadows starts with a little exercise. What do we understand by sustainable development? He shows two pens: an expensive brand pen and a cheap pen made from recycled materials. Which one is more stustainable? The question seems to be easy. But after a moment, he explains that the first pen will stay for a long time and will be re-filled, while the second one will be thrown as the ink is more expensive than the pen. Some people after the explanation changed their mind, after being given new information. However, this was only personal opinion. The responsibility is on our side. Will we change our habits? What do we think is more sustainable?
