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

As per the latest Water body database (it need correction), Telangana has the most number of large water bodies. They classify their Cheruvu as Tank, we say it as lake. TS spent more in their water resources in last 10yrs than TN spent in last 50+yrs. TS renovated many tank/lakes
WRIS report put Tamil Nadu as a State with most number of large water body. Just Water body database put Telangana as the state with most number of large water bodies. The later is bit more accurate than the former
This is the list as per latest waterbodies database, As per this list, AP has the most larger waterbody by area followed by TS and TN Image

There is lot of misinformation spread in media abt TN Cauvery water use
1. As of now, KA is opening ~5000cusec to it's irrigation canal just from Kabini and KRS, saying KA will use the present
storage only for drinking is incorrect.
2. TN is opening ~5000cusec to Delta 1/n
3. Using TN NEM monsoon as excuse is misleading because Mettur local catchment receive less NEM monsoon than Delta. TN need water in Mettur for drinking water.
4. Many cities in TN depends on Cauvery for drinking water(i.e. Erode, Salem, Karur, Trichy, Tiruppur..etc) 2/n
5. Most of the delta only grow two crops, many use pump set. Though delta is fertile for multiple crop. It is ideally suited for paddy cultivation
6. NEM is a unpredictable monsoon with heavy rain in few days, Samba crop need some growth to withstand NEM onset 3/n

Talk of delimitation is alarming for TN. In 1957, TN had 8.3% of seat in Lok Sabha(41/494), in 1976 TN had 7.2% of seats in Lok Sabha(39/543). If Centre come with 1 person 1 vote, the delimitation will reduce TN share to 5.5%. That is removing 24% of TN current representation 1/3
Image
Image
Argument of 1 person 1 vote can't be accepted in India, becoz in 1976, it is the govt of India that "mandated" states to control the population, froze the percentage of representation. Now, centre can't come and say April fool to the state that followed the mandate 2/3 Image
State that followed the govt mandate can't be punished by changing the rule of the game. It is like announcing the person who came last as 🏆 winner. The populated state can be given more local body seat by upgrading status of their local bodies.I hope relational mind prevail 3/3
