Question

what are the resources that the state tamilnadu is deficient in

Answer 1

copper
zinc
iron ore
chromite

Answer 2

Tamilnadu Contributes lot of Natural resources to all other States on India generously, but get back little in my opinion. In Fact Tamilnadu is losing it natural charm because of this excess sharing, hurting the interest of the state. (The proposed Methane gas project is an example) .

In addition to legal sharing smuggling of great resources like Sand to Sandalwood also happens but I exclude that. There is no use in listing that. Nothing is going to stop..
