The wetlands are threatened due to Silting due to soil erosion.
A wetland is a place in which the land is covered by water salt, fresh, or somewhere in between either seasonally or permanently.
Increasing human activities and their negative consequences cause pollution, degradation, and loss of wetlands. The main threats that the wetlands struggle with are unsustainable and non-eco-friendly human activities.
Soil erosion caused by heavy floods is a matter of concern as it leads to several associated problems like changes in river course, causing loss of land, damage to the embankments, etc.
