At the present moment everyone is engaged in technological advancement, which is described in Bhagavad-gita as ugra-karma — extremely severe endeavor. This ugra-karma is the cause of agitation within the human mind. Men are engaging in many sinful activities and becoming degraded by opening slaughterhouses, breweries and cigarette factories, as well as nightclubs and other establishments for sense enjoyment. In this way they are spoiling their lives.

From Srila Prabhupada’s purport to Srimad-Bhagavatam 7.14.10
