Its pity that we destroy the forests on the banks of the rivers, remove trees on the hills, and allow silt to accumulate in the lakes. All this leads to destroying water bodies. It's fury of nature that kills people and makes them homeless world over.
When people will learn to love plants and protect them if they want to protect their homes and environment.
See below the lake manesar of Jaipur surrounding Jal Mahal  which has been encroached upon to make tourist spot but filling of lake with sand has destroyed its structure choked water ways to lake and make it dry in times to come. Water bodies are living systems. Once you destroy their limbs they will die slow death. Save plants , save planet or face the natures fury. Choice is yours .
