Is there anything that we can do to save the estuaries, us too?

Yes, to start with we can follow the following suggestions:

1. Prevent dumping solid wastes, effluents and sewages into estuaries or any biologically productive water bodies; or, purify (‘treat’) them from dirt and chemicals before letting them into estuaries.
2. Avoid overfishing and use net with appropriate mesh-size.
3. Follow coastal zone regulations.
4. Avoid further human settlement.
5. Encourage more ecological analyses and biodiversity inventories.
6. Barcode all the presently available organisms and discover new ones. Use the data generated using barcoding for monitoring the ecosystem to find out changes in biodiversity.
7. We must take individual, as well as collective, effort to understand the values and functions of the ecosystem.
8. We must try to understand the deeper values and meanings of the existence of rivers and estuaries in our ancient literature/scripture of sages. That way we may be able to realize the importance and significance of having such water bodies.
9. We must try to educate each other about our surroundings, everything we consume or use.
10. Create awareness of misusing our environments.
