Tamils get things done either by deceiving or by threating others. They are definitely smart people but that does not work in issues like Cauvery water.
If you see Karnataka is very different geographically due to geographical position of Nilgiri hills and effect on rain fall due to Arabian sea currents. Karnataka follows slightly different season cycle than rest of the country. Most of the people do not know this and their dependency on river water is lot higher.
On the other hand Tamilnadu should do a better water resource management and rain water harvesting. Bay of Bengal is more dependable for rains as it has immediate effect of low-pressure in sea. Every other year we see floods in chennai and other parts of tamilnadu and in just few weeks there's scarcity for water.
(i know one of my friends had to buy around 20 water bottles to finish his bath to go to a job interview and that's Chennai!!!)
I think the following can help: Karunanidi should remove his dark glasses and see the reality. Jaya amma should stop shopping jewelry and shoes and spend sometime on this issue. Finally, Rajni should stop punching dialogues and do some social work.
