A few years ago I liked to play Age of Empires on my PC till I got bored with the game: in the end it all came down to the same challenge of surviving with the scares resources.
I could see how the amount of fish in the seas was dropping and how the natural resources were thinning out. All resources sooner or later got exhausted and I had no other choice but launch a war against my allied and often unsuspecting neighbor. There was one resource that I never got short of – water. Yet it is water we need to actually produces almost everything around us starting with food and clothing to steal and chemicals to operating a mine and generating electricity.
- 2,5 liters of water to produce one liter of gasoline;
- 2.700 liters of water to make a cotton t-shirt
- 16 000 liters of water to produce a kilo of beef
- 16 000 liters of water to grow enough crops to produce a liter of biogas
These stats from the daily paper gave me chills and made me sink deeper into the chair of the commuter train. I remembered the story of Easter Island and its inhabitants. It is believed that the islanders themselves were responsible for the deforestation of the island through extensive sheep farming and agriculture. Having no trees left they could no longer build canoes to take them out in the sea fishing. They ended up eating their dogs and the nesting birds and took up cannibalism. Their magestic moai (statues) witnessed the downfall of the people who had carved them to stand there for ages and yet had failed to think in the long run. The islanders were crushed by their own thoughtless consumption.
