6,000-kilometer journey – and now threatened: what Mallorca's eels really lack

Answer

What is salinization and why does it matter in Mallorca?

Salinization happens when seawater moves further inland and makes freshwater areas saltier. In Mallorca, heavy groundwater use and hotter, drier summers can increase that pressure on ponds, canals and other habitats. For fish and eels, it means fewer suitable places to live and grow.
