Last week the U.S. Department of Agriculture awarded a $3.9 million grant to develop a mechanical sprayer. The chemicals used in vineyards have become so toxic that they are considered a health hazard for humans. In other words, the government is trying to find a way to make spraying highly toxic chemicals on grapes more convenient. And we haven't even reached the end of this expensive and ultimately deathly spiral yet - eventually the pests and weeds will become resistant to what we already consider to be highly toxic chemicals. How much poisonous substance can we survive?
