GM soy: the high cost of the quest for green gold

Scientists and villagers in rural Paraguay are questioning the health and environmental impact of GM soy. Louise Gray reports.

The green shack where Petrona Villasboa lives in Itapu is surrounded by shimmering fields. It represents a lucrative golden harvest for some but, for this grieving mother, it has become a symbol of death. The crop that dominates this impoverished area of rural southern Paraguay is genetically modified soy, and she blames it for her sons death. Soy destroys peoples lives, Petrona says. It is a poison. It is no way to live.

Sitting outside her home, the mother of eight describes the day in January 2003 when 11-year-old Silvino Talavera arrived home. He had cycled to the stalls by the nearest main road to buy some meat and rice for a family meal.

I was washing clothes down by the river, and he came to tell me that as hed ridden along the community road, which runs through the soy fields, hed been sprayed by one of the mosquitoes, she says. He smelt so bad that he took his clothes off and jumped straight in the water.
