The Breath of the Earth (BRO)

The earth "breathes". This is particularly visible in karst landscapes, which are formed by the dissolution and carbonic acid weathering of calcareous rock. Typically, caves, springs, sinkholes and underground river systems can be found here. In such landscapes, water, rock, air and life interact. The Erasmus+ project "Breath of The Earth" (BRO for short) enables pupils from different regions of Europe to get to know the karst phenomenon. The focus is on carbon dioxide, which acts as a mediator between inanimate matter and living nature. The aim of the project is to make natural phenomena tangible and to understand ecological relationships. This homepage presents the activities of the project and the karst regions explored.
