How Eichhornia crassiper spoils the Indian ecosystem ?

Explanation

Eichhornia crassipes is an invasive weed native to South America. It was introduced as aquatic ornamental plant, which grows faster through the year. Its widespread growth is a major cause of biodiversity loss worldwide. It affects the growth of phytoplanktons and finally changing the aquatic ecosystem. It also decreases the oxygen content of the waterbodies which leads to eutrophication. It poses a threat to human healt because it creates a breeding habitat for disease causing mosquitoes (particularly Anopheles) and snails with its free floating dense roots and semi submerged leaves. It also blocks sunlight entering deep and the water ways hampering agriculture, fisheries, recreation and hydropower.
