Spanish transportation company Refne wants the environment lovers to know that they had the wellness of the planet on their mind when they designed their trains.
How did they do it? By imitating nature!
"The best way to protect nature is by imitation," explains their ad campaign.
It goes on, "The frontal design inspired by the eagle head makes the train 25% more energy-efficient."
Another model goes for the duckbill nose, which makes the train 30% more energy-efficient.
The campaign is created by TBWA\Madrid, Spain.
