The Bhopal gas tragedy was the worst industrial disaster in human history. Twenty-five thousand people died, 500,000 were injured, and the injustice done to the victims of Bhopal over the past 25 years will go down as the worst case of jurisprudence ever.
The gas leak in Bhopal in December 1984 was from the Union Carbide pesticide plant which manufactured "carabaryl" (trade name "sevin") – a pesticide used mostly in cotton plants. It was, in fact, because of the Bhopal gas tragedy and the tragedy of extremist violence in Punjab that I woke up to the fact that agriculture had become a war zone. Pesticides are war chemicals that kill – every year 220,000 people are killed by pesticides worldwide.
After research I realised that we do not need toxic pesticides that kill humans and other species which maintain the web of life. Pesticides do not control pests, they create pests by killing beneficial species. We have safer, non-violent alternatives such as neem. That is why at the time of the Bhopal disaster I started the campaign "No more Bhopals, plant a neem". The neem campaign led to challenging the biopiracy of neem in 1994 when I found that a US multinational, W.R. Grace, had patented neem for use as pesticide and fungicide and was setting up a neem oil extraction plant in Tumkur, Karnataka. We fought the biopiracy case for 11 years and were eventually successful in striking down the biopiracy patent.
Meanwhile, the old pesticide industry was mutating into the biotechnology and genetic engineering industry. While genetic engineering was promoted as an alternative to pesticides, Bt cotton was introduced to end pesticide use. But Bt cotton has failed to control the bollworm and has instead created major new pests, leading to an increase in pesticide use.
