**The Quiet Decline of Forests Molecules: How a Finnish Scientist Tracks Lichen Loss From Pollution** Every year, vast natural systems show signs of strain—ecosystems shift, species adapt, or retreat. A quiet but measurable story unfolds each season in Finland’s untouched woods, where a dedicated scientist tracks a tiny but vital organism: lichen. Studying how a lichen species loses 5% of its area each year due to pollution, this research reveals broader patterns of environmental degradation—and what it could mean for biodiversity across the U.S. and beyond. Starting with 1,000 square meters, understanding the full impact after seven years unveils a sobering yet revealing trajectory. --- **Why A Finnish scientist studies a lichen species that loses 5% of its area annually due to pollutants.
