I'm surprised that the author hasn't mentioned the use of toxins (pesticides)[1], to the extent that it is even being used as a real pesticide in various parts of India.
I know some may find this offensive, but sorry, I think I have a moral responsibility myself to let the people around me know of the harms caused by this carcinogen[1].
Cheers.
