Botulinum toxins are the most lethal toxins known. For type A toxin, the toxic dose is estimated at 0.001 mcg/kg (Franz 1997); the lethal dose for a 70-kg person by the oral route is estimated at 70 mcg, by the inhalational route 0.80 to 0.90 mcg, and by the intravenous route 0.09 to 0.15 mcg (Sobel 2005).
1 hectare = 2.47105381 acres. .07 hectare= .17 acres per person. about 7500 square feet per person. While this figure produces a result of around 5-6 people per acre, there are plenty of caveats to consider. If the soil is not ideal, increase the land. If the growing season is short, increase the land.
