In the Faroe Islands, a team of biologists is studying these marine plants with the aim of improving salmon farming and avoiding the need for drugs or chemicals. In Munich, others are working on a tiny algae whose high oil content could eventually replace petroleum. The carbon fiber obtained from it is a real match for fossil fuels. In France, a tower resembling a Morris column is being used to purify the air. The tower absorbs one tonne of CO₂ per year - the equivalent of several dozen trees - and converts it into oxygen.

Every year on Earth, hundreds of millions of hectares of vegetation are swept away by flames. During the summer of 2018, Europe experienced a foretaste of the foreseeable consequences of climate change, with record temperatures and extreme drought leading to forest fires on an unprecedented scale, particularly in Sweden. How can we better prevent and control these fires, over 90% of which are man-made? Climatologists and specialists are joining forces to provide the best possible response to this threat. From increased prevention among young people, to innovative detection systems and the planting of cypress trees to block the flames, methods are being studied to combat this scourge from France to Spain and Germany.
