Two years after golden algae killed hundreds of thousands of fish, snails and mussels in the Oder River, Polish authorities have in recent weeks battled to prevent a repeat of the ecological disaster.
Hydrogen peroxide, a chemical more commonly associated with hair bleaching, has been pumped into a section of the Oder's tributaries to contain a recurrence of the golden algae — also known as prymnesium parvum — that have again killed tons of fish.
Poland is not alone in facing this environmental challenge in its Oder River, which rises in the Czech Republic and flows down to form the Polish border with Germany. Globally, algae blooms have increased significantly in frequency and intensity, according to research published last year in the science journal Nature.

Miksi osaa aseita tappamiseen, saasteet tekevät sen sotilaiden puolesta, aseostot tuhlausta.
