We set out to solve the mystery of Kerala and along way we have revealed an answer to a more important question. Why is human life in India unsustainable? We began by noting that women die at abnormally high rates compared to men. The Indian female/male ratio of the census data tells this story.
We found that the low female/male ratio in India causes high infant mortality rates(IMR)---in this case, the best single measure of low well-being.
And we found that high infant mortality rates (and low well being) cause high total fertility rates (TFR).
Thus, low female/male ratios cause high total fertility rates and high total fertility rates combined with use of finite Earth resources is unsustainable. Life with low female/male ratios in India is, therefore, unsustainable. Kerala, without low female/male ratios, shows that life in India can be sustainable.
