<ul>
<li>Finnish water environments are fragile.</li>
<li>Eutrophication is caused by nutrient emissions from human agriculture, habitation, and industry.</li>
<li>Eutrophication threatens water ecosystems by changing their delicate balance.</li>
<li>Dams are a threat to river ecosystems.</li>
<li>Acid rain caused by industrial toxins can cause the acidification of water ecosystems.</li>
<li>Invasive species can threaten the survival of native species.</li>
<li>Key words: eutrophication, lack of oxygen, cyanobacteria, acidification, hydraulic engineering, environmental toxins, invasive species.</li>
