Just imagine the government feeding the stray dogs that are mauling the children & weak in the city of Bengaluru.
Yes, BBMP, the city council of the Silicon City of India, decides to feed the stray dogs with chicken and rice in the premise of beating their hunger. With countless cases of the strays mauling kids & weak citizens of the city in the past many decades, instead of curbing their rising numbers by a sterilization programs, it in fact feeds them, thereby promoting good health & reproductive capabilities.

In another classical blunder, the same/similar authority goes on the beautification of the lakes by clearing the garbage dumped into it (which is a good thing) but also eradicates the delicate eco-system of trees, grasses, & plants that lined the periphery as a natural eco system. According to Priyanka Jamwal, Programme Lead (Water and Social programme) and Senior Fellow, Ashoka Trust for Research in Ecology and Environment (ATREE), a majority of the lakes in the city that have been rejuvenated by Bruhat Bengaluru Mahanagara Palike (BBMP) wear the same look, more or less.
But this is not good algae. The green colour of these lakes is due to the excessive growth of a tiny organism, cyanobacteria, mainly due to the presence of nutrients in the water, experts say.
The bacteria grow rapidly in the presence of nutrients such as nitrogen and phosphorus. Nutrient levels in these lakes go up either due to internal or external loading.
External loading happens when secondary-treated or raw sewage enters the lakes. Internal loading is due to the release of nutrients from lake sediment.
Jamwal says the reason behind excessive nutrients is a lack of shoreline vegetation.
“Shoreline vegetation creates a delicate balance in a lake ecosystem. If removed, cyanobacteria are exposed to a large amount of sunlight, which increases their capability to multiply exponentially. After the bloom, the bacteria also die at the end of the life cycle, forming a layer of organic matter at the bottom of the lake. This organic matter starts decaying, which causes a further dip in oxygen level,” said Jamwal.
