Detailed explanation-1: -Algal blooms can reduce the ability of fish and other aquatic life to find food and can cause entire populations to leave an area or even die. Harmful algal blooms cause thick, green muck that impacts clear water, recreation, businesses and property values.
Detailed explanation-2: -Exposure to high levels of blue-green algae and their toxins can cause diarrhea, nausea or vomiting; skin, eye or throat irritation; and allergic reactions or breathing difficulties. Pet and livestock illness/deaths can happen if animals consume large amounts of water containing blooms, scums or benthic mats.
