Wild Card's description 
By mid-2010’s scientists in Europe discover new algae species from Mediterranean Sea which can be used very efficiently and very broadly in biofuel production. Soon after that the scientists discover a new scientific principle for producing huge quantities of cheap biofuel from the new algae species as well. Then international political leaders and organisations realize that algae is, not only a cheap and carbon neutral form of energy production, but also a good way to carbon caption form atmosphere. This is realized by customers around the world as well, which leads to huge demand on algae biofuel. Suddenly algae production become the globally accepted and heavily subsidised way to fight the climate change.
