Bengaluru Lakes Ecosystems Threatened by Pollution and Invasive Species

Bengaluru Lakes Ecosystems Threatened by Pollution and Invasive Species

Bengaluru's lakes, once home to unique ecosystems, are now facing serious problems.

Pollution and invasive species like tilapia and water hyacinth are causing harm.

These invaders take over the lakes, making it hard for native plants and animals to survive.

Experts say that if things don't change, these ecosystems might disappear.

The lakes were built by locals long ago to collect rainwater, but now they are filled with wastewater and dredged to a uniform depth, which disrupts the natural balance.

This has led to the loss of many native species and the spread of invasive ones, which are better at surviving in polluted water.

The situation is critical, and immediate action is needed to save these important water bodies.
