"China and India have the right to industrialize themselves using the same tools Western countries have used. China is leading the world in alternative energy manufacturing making clean energy profitable and India is the 4th largest renewable energy producer."
I found the study that the article bases this on[1]. It doesn't make this claim and instead associates a higher mortality rate to sufferers of all mental disorders, 67% of which are deaths by natural causes. That these natural causes are directly associated with the mental disorder isn't even something the study says. Anxiety is just one of the many disorders analyzed.
This is similar to attributing a lower life expectancy to all people with endocrine diseases (e.g. diabetes) and later saying hyperthyroidism (another endocrine disease) is the sole cause of death in that group.
