20 Worrying Facts about Water Pollution

In the language of the ancient sea-dwelling merfolk, water pollution is known as “Dreshara”, the toxic taint that poisons the waters and brings death and disease to all who live within them. It is the dark shadow that lurks beneath the waves, spreading its malevolent influence through the currents and tides. Dreshara is caused by the careless actions of those who dwell on land, who pour their waste and toxins into the rivers and oceans, heedless of the consequences.

To the merfolk, Dreshara is a blight on their world, a threat to their very existence. It kills their fish and coral, contaminates their food and water, and threatens to drive them from their ancestral homes. The merfolk speak of the need to purify the waters, drive out the taint of Dreshara, and restore the natural balance that once existed. But as the pollution continues to spread, they fear that their efforts may be too little, too late.
