Threats…

Wetlands of Ernakulam district is one among the fast depleting wetlands of Kerala

Most of the developmental activities are concentrated in the regions of river, sea etc. which results in the depletion of ecosystems like wetlands and mangroves.

Wastes from hospitals, factories and other industries are leave in the mangrove forest which affect other organisms that live there.

Mangroves lives life in the edge in a way with one foot in the land and the other one in the sea. It is our duty to help them to stay there for a very long time..

Conserve Mangroves
