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

If I were to be Samsung, if the option is between shifting the factory or accepting CITU. I will choose shifting the factory. People have no idea, what is the actual consequences of allowing CITU inside the production line. It is better to save the Brand name than factory 🧵 1/n
If a company allow CITU, they will loose the control over their production line, for high tech electronics company, it is like committing suicide. You can't control quality, u cant change the low quality employee. Political party (CITU is full of poltics) will dictate it 2/n
High tech electronics appliances has many components, even single assembly issues will create bad quality product, unhappy customer. Within a year, a company will loose the market. Most importantly its brand name. Samsung brand name more important than a manufacturing plant 3/n

Many heritage structures of Madurai incl the fort walls, orchids..etc were demolished by British. Many temples were in ruins. The pillars of the front mandapam was sold to Adeline Gibson, now displayed in the world famous Philadelphia museums. Adeline died at young age 2/3 Image
British were impressed by the ruins of Thirumalai naikar mahal, they renovated the palace, but didnot maintain the temples. In last 80yrs, many temples were renovated. Though not popular, Even today, Madana gopalsamy temple is worshipped by devotees of Madurai 3/3

Extending BMRCL upto Hosur is now a hot topic, hearing lot of angry voices. In 1973, TN govt setup Hosur SIPCOT due to proximity to Blre. Post 1991, Hosur saw decline. From 1998, KA started building, its largest Bommasandra industrial cluster using existing Hosur ecosystem 1/6
Image

Hosur never competed with Bengaluru, it complimented it. Tamil Nadu/Hosur went through severe electricity crisis during 2009-13, political crisis btw 2014-17. During this time KA overtook TN in industrial investment. Built it's largest industrial ecosystem around Bangalore 2/6 Image
Having, intra state industrial ecosystem is beneficial to both states. It will ensure bad policy of one state doesn't affect whole ecosystem. Hosur and Bengaluru benefited from each other. From 2017, TN govt been proactive, so Hosur industrial system is reviving 3/6 Image

TN is No.1 in destroying beaches with waste. With illegal shop, irresponsible people, & failed govt.
Marina beach is gone, then we lost Besant Nagar beach, Ariyamaan beach is also down with waste. It is sad to see once clean Mahabalipuram beach is also occupied by illegal shop. Image
Most of these shops are controlled by local goons, these shop owners pay their rent to them. Regulating these shops by local bodies will fetch more revenue to them will help to keep it clean, but deprive mafia's their money. Shops went till beach water, getting worse in last 5yrs
I know, whatever I post in Twitter will have zero impact on the ground. It is a system run by the mafia, for the mafia. I request people to boycott beach shops, we can only do them.

My post on Vijayawada flood is misinterpreted by many. This post elaborate it.
Let us start with Vijayawada drainage basin. It is part of Krishna & Budameru basin part of Kolleru lake. Budameru basin has ~900sqkm of catchment basin till Vijayawada city with hills and lakes. 1/n

Vijayawada is not new to flood, In last 100 yrs, city went through 17+ floods driven by both Krishna & Budameru rivers. In 2005, Budameru created heavy flood in the northern part of the city, since it flows through the heart of the city. AP govt decided to divert the water 2/n Image
After 2005 flood, AP govt decided to prevent Budameru river from entering the core part of the city. So, it planned to divert the river into Polavaram canal (connects Polavaram to Prakasam). Budameru wonot enter city. Polavaram canal has ~37000cusec carrying capacity 3/n Image

All these floods are not due to Krishna river but because of small Budameru vagu, it has ~900 sqkm catchment till Vijayawada. After 2005 flood, AP govt diverted part of the river into Krishna by connecting it with 37500 cusec Polavaram canal, still it overflowed the canal 1/2
Due to heavy rainfall Budameru saw >60000 cusec, overflowing both the diversion canal & it's natural river course. It's natural path is illegally occupied, it can't even carry 10000 cusec flood. So water overflowed from the canal and the river, flooding the Vijayawada 2/2

Though it flows close to Krishna river, Budameru is not part of Krishna basin. It is part of Kolleru lake basin. Budameru meet the largest freshwater lake by area in India. Kolleru is an another ecological disaster. AP rivers are seeing man-made impact
