A very large algae bloom in Lake Erie, North America, which can be seen from space. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in fresh water or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. [1]
Water, carbon dioxide, minerals and light are all important factors in cultivation, and different algae have different requirements. The basic reaction for algae growth in water is carbon dioxide + light energy + water = glucose + oxygen + water. [59] This is called autotrophic growth. It is also possible to grow certain types of algae without ...
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
Climate change has storms sending untreated sewage spilling into NY waterways, while fueling harmful algae blooms. What to know before swimming. Sewage, algae blooms, flesh-eating bacteria: Is ...

The microcystin-producing Microcystis is a genus of freshwater cyanobacteria and thrives in warm water conditions, especially in stagnant waters. [7] The EPA predicted in 2013 that climate change and changing environmental conditions may lead to harmful algae growth and may negatively impact human health. [20]
The growth of dense algae in surface waters can shade the deeper water and reduce the viability of benthic shelter plants with resultant impacts on the wider ecosystem. [24] [49] Eutrophication also decreases the value of rivers, lakes and aesthetic enjoyment. Health problems can occur where eutrophic conditions interfere with drinking water ...
The green scum shown in this image is the algae bloom in Lake Erie. Within aquatic ecosystems, algae assumes a pivotal role by utilizing photosynthesis to transform water and carbon dioxide into sugar, concurrently releasing oxygen as a by-product. However, inadequate management can create significant environmental consequences.
