Bring owls to Athens

"To do or undertake something redundant, pointless, or futile. It refers to the city of Athens in the time of Ancient Greece, where silver coins were minted with the image of an owl (which were abundant in the city). Thus, to bring either owls or silver to Athens would be a useless venture."

City of Tampere first spent years to decide what would be the most prominent addition to the public transportation. Then they decided to build a tramway through the town.

Now trees are cut down, and roadworks are blocking the traffic for years.

Over ten years ago I read an article saying the town could have built a system to collect biogas at the local wastewater treatment plant, and run the buses with that gas.

It looks like we human beings can't do anything else but to hold up the inevitable...

Well, I guess it's time to plant yet another tree.
