A spectacular backlash, including threats against a scientist. A $150,000 grassroots campaign is crushed by a $5million corporate counterblow. Whole countries have changed policies, and we may be next. The link? GM foods, and the backers of agricultural biotechnology.

Part one of Seeds of Trouble investigates the truth behind the conspiracy theories and the alleged bully boy tactics by the GM food industry - and its biggest fan: the US government.

Genetically modified (GM) food was supposed to be the bright new dawn of agriculture, and the answer to world hunger. It unleashed a biological goldrush, which turned sour when shares lost value, debts mounted, and the corporations got rid of their agricultural biotech divisions, leaving them to sink or swim on their own.

At the same time, pressure mounted on individual scientists, on activists who fought for the labelling of GM foods, and on various countries including those in the EU.
