In Palavakkam, a suburb of Chennai, the stretch of beach sees Olive Ridleys laying eggs in the shore. To encourage the turtle breeding and to not confuse the hatchlings with too much illumination in the darkness of the night, the street lights are strictly switched off. This ensures that the turtle hatchlings make their way to the sea in their still unsteady tiny feat. The neighbourhood volunteer self-styled environmentalists help the stranded ones reach the waters safe. Olive Ridleys breed through stretches of the eastern Coromandel coast of India. The state pf Orissa is another popular pick for them with its pristine virgin beaches with minimum recorded human footfall. As awareness kicks in, locals now make sure that the olive ridley hatchlings survive. And therefore the south east coast of India remains the olive ridleys’ favourite destination when it comes to breeding. To encourage the adult female turtles to lay their eggs in the beach sand, the switching off of street lights is encouraged and practised. This shows that we are a responsible society willing to go the extra mile to see that wildlife is nurtured. Conflicts arise mostly when there is damage to property and/or loss of human life as it happens in the elephant corridors where human settlements bifurcate forest reserves.
Anyway, that is how my interest in olive ridleys happened. For sighting, one can plan an outing. This extraordinary adventure is open for city dwellers without pinching their pockets.
It sounds implausible that the cousins of Olive Ridleys, the Green Turtles must be behind the environmental destruction caused by disappearing seagrass meadows with their mass feeding frenzy?! It comes as a shocking surprise that sometimes specific wild flora and fauna may turn out to be the agents behind driving to extinction many other co-existent wild species vying for survival in the same shared environment or eco-system. Of course, if wheat and paddy are widely cultivated and thriving crop species today, once upon a time they must have been the weed that drove to extinction better cereals/food grains. Like the poultry and cattle, maize and wheat are winners by mere mindless propagation. Green turtles to me sound like these hollow winners of the ecological war. Besides, it is news to me that the seagrass can capture and block at least eighteen percent of global carbon. It means the seagrass may be having a direct and significant role in oxygen quality in planet earth. Precisely this seagrass is fodder for dugongs, green turtles and other sea creature that mostly graze them to extinction. Reading of the green turtles in swarms feeding on the leaves and then even digging out the roots of the sea grass, one is reminded of the human greed. Green turtles have no geographic home ground. They are on the move for the entire span of their lives moving enmasse from one atoll to another, in search of seagrass, their staple food. They circumnavigate the earth thus from Cuba to Indonesia, India to Maldives and Pacific islands. In India, for a while, the Lakshadweep lagoons served as their feeding grounds before they grazed them seagrass meadows to near extinction. And then they were gone. Refer/recommend the book ‘At the feet of the living things’ yet again, authored by research scholars backed by NCF Aparajitha Dutta and others.
Seagrass meadows, the savannahs of the ocean are also the ecosystems that sustain a plethora of fish families besides supporting the turtles, dugongs and the like. Correlated to the corals and the mangroves, the seagrass meadows play a vital role in sustaining living organisms in the planet. Kudos to research scholars and NCF, India for coming up with unconventional ideas to protect and propagate sea grass and thus saving it from total extinction in this part of the world.
Mother nature maintains a delicate balance: the green turtles have to survive and the seagrass meadows also must flourish giving earth a chance to breathe. The key to Planet Earth’s survival lies under the oceans: in the profusion of seagrass meadows that absorb the excess carbon from the atmosphere and keep it all locked down fathoms beneath them cleaning up the oceans.
Wow now I do wanna go for snorkelling! I didn’t capitalize on a dozen chances I got in life, out of … er.. kind of phobia 😀 but then what a terrible loss this is. I must, the next time opportunity presents itself.
