Navi Mumbai’s lakes turn too toxic for Flamingos
If it's too toxic for flamingos, how healthy is it for the people living nearby?
What's happening?
- Flamingos are seen in Mumbai every winter, as part of their annual migration. The Thane Creek Flamingo Sanctuary is the main site where these birds come, but there are 3 other lakes in Navi Mumbai that serve as satellite wetlands.
- A recent study showed very high levels of pollutants in these 3 lakes, as much as 3-4X of the safe limits. This ties up with the observation of fewer flamingoes being spotted in these lakes this year.
- Experts blame blocked tidal flow that helps regulate pollutants and untreated sewage flowing into these lakes.
- Activists recently wrote a letter to the PM, and the Center has now asked the state to take immediate action.
Why should you care?
- Flamingos can only thrive in healthy wetlands. With such high level of pollutants their food chain will collapse and the birds will stop coming.
- If the wetlands are too toxic for flamingos, how healthy do you think they are for the humans or other life around the area?
- Beyond flamingos, wetlands act as natural water filters, flood buffers, and carbon sinks. When they degrade, we lose our defence against waterlogging during monsoons, groundwater quality drops, and local temperatures rise.
