In Green Matters Mia Mäkelä approaches environmental issues such as eutrophication of the Baltic Sea from a new angle. She experiments with green algae, an essential source of oxygen with prospects of being it for energy and food in the future, and explores their possible use with traditional rug-making. In the process Mäkelä engages with an eclectic set of knowledge, ranging from marine biology to environmental politics.
