Invisible Waters

Ana Sofia Reboleira

Beneath our feet lies a hidden world of groundwater. Not only does this give life to unique ecosystems, but it is also where much of the water we drink is found. In this conference, Ana Sofia Reboleira reveals the vital importance of these ‘invisible’ waters, the surprising biodiversity that lives in them, and the importance of taking care of this biodiversity if we want to keep our water drinkable.

Researcher, speleologist, and professor at the Faculty of Sciences at the Universidade de Lisboa, Ana Sofia Reboleira has discovered more than 70 species new to science and has led expeditions into caves on all continents except Antarctica. A journey to the Earth's water tables, reminding us of the urgency of protecting what we rarely see, but which is vital to us.
