Over 70% of the earth is covered by water. Due to the scarcity of land, it is interesting for me as an interior architecture student to study alternative habitats (for example the sea) for us humans. But as I am a diver, the preservation of the ecosystems and the beauty under water is always connected to it. Since reefs also serve as protection for island groups, we should pay even more attention to protecting and conserving them. Since reefs, in addition to their preserving beauty, are also able to maintain our habitat on land. For this reason, I am working currently on the topic of living on the water and the protection of reefs.
