Recently we have heard about a lake which water turned into pink color and it was the big cause of everyone’s wonder….everyone was surprised that how it happened ….then every had curiosity to know about that lake and to know about how it’s green color changed into pink color……and the name of that lake is the LONAR LAKE…….
The lonar lake is located at Lonar in Buldhana district, Maharashtra, India. Lonar Lake was created by an asteroid collision with earth impact during the Pleistocene Epoch.
The lake was initially believed to be of volcanic origin, but now it is recognized as an impact crater. Lonar Lake was created by the impact of either a comet or of an asteroid. The crater has an oval shape.
The water of the lake contains various salts and sodas. During dry weather, when evaporation reduces the water level, large quantities of soda are collected.
The lake is a haven for a wide range of plant and animal life. Resident and migratory birds such as black-winged stilts, brahminy ducks, grebes, shelducks (European migrants), shovellers, teals, herons, red-wattled lapwings, rollers or blue jays, baya weavers, parakeets, hoopoes, larks, tailorbirds, magpies, robins and swallows are found on the lake.
In early June 2020, the lake turned red/pink in a span of 2–3 days. A report by Agharkar Research Institute, National Environmental Engineering Research Institute and Geological Survey of India suggested that lowered water levels and high salinity caused growth of Halobacterium and increased Carotenoid levels, which in turn led to color change.
PROBLEMS OF LONAR LAKE-
• Use of fertilizers, pesticides and toxic materials in the agriculture field around the lake results in pollution of lake water.
• Deforestation is illegally carried out in the surroundings and cattle grazing inside or near the rim of the crater creates fecal pollution.
• Excavation activities are often carried out illegally thus disturbing the lake’s underground water source.
• The lake’s ecosystem is being damaged because of the sewage dump in the lake.
• Commercial activities, including illegal construction, within the vicinity of lake has damaged the lake’s natural.
There are various activities (e.g. “Save Lonar”) for the protection of Lonar crater are on-going.
