While many chimpanzees are naturally hydrophobic, Sakamaki (1998) found that those in Mahale have been observed to submerge themselves into freshwater and eat algae. [7] This observation is the first documentation of a primate using algae in the wild as a food source and is an important marker of possible adaptation in the species.
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.
Home composting can limit landfill waste and therefore, methane emissions as well. [7] When food waste is thrown out and ends up in waterways, it can contribute to algae blooms. [25] Algae blooms can produce toxic emissions that have harmful health effects on mammals and organisms, including humans. [30]

That's because the stakes of deciding where — and when — to swim have risen, as climate change supercharges storms that send untreated sewage and other pollution spilling into New York ...
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]
Some predatory algae have evolved extreme survival strategies. For example, Oxyrrhis marina can turn cannibalistic on its own species when no suitable non-self prey is available, [ 11 ] and Pfiesteria and related species have been discovered to kill and feed on fish, and since have been (mistakenly) referred to as carnivorous "algae" by the media.
Sea lettuce as a food for humans is eaten raw in salads and cooked in soups. It is high in protein, soluble dietary fiber, and a variety of vitamins and minerals, especially iron. [5] However, contamination with toxic heavy metals at certain sites where it can be collected makes it dangerous for human consumption. [5]
