Let us protect our Bio diversity and topography #Nilgiris 6/7
TN is known for its flora(plant) diversity(comes in top-4) & Amphibian diversity. With important bio-diversity spots like Nilgiris, Anamalai, Agastiyamalai, Meghamalai, Palani hills & Eastern ghats. All this in very high population density with less than 1/3 per capita water 7/7
The conclusion is, we live a diverse state that is worth protecting not just for us but also it has something to offer for entire world. As a region that is much below world average economic prosperity, we have lot to go forward but need to find a balance to protect what we have

In the Navaratri session, many in northern India are fasting with Sabudana(Javvarisi/Sago) diet, Sago consumption peaks in India. Salem district in Tamil Nadu is called Sabudana/Sago capital of India, 80% of Sago comes from here 1/4
📷- Sago factory, Salem
Sabudana/Sago is used as a stable food in China for millennia, where it is made from Sago plants. But in India, Sago's are made from Tapioca(cassava). Tapioca was introduced to India(Kerala) during 1860's as a famine food, Sago is introduced to India in the early 20th century 2/4 Image
The first Sago factory in India started in Salem in the early 1940's. Tapioca from Kerala is brought to Salem to make Sabudana. In the early 2000's, TN govt financially funded the industry as a sago cluster. Now, it is grown into a bigger industry with high-tech machines 3/4 Image
