2 nanograms is how much neonicotinoid poison it takes to kill a honey bee. Hard to visualize isn't it. So... maybe the follwing would be a better perspective.

Assume a healthy hive has 60,000 bees. In Texas, there are about 80,000 hives, so thats 4.8 billion bees (60,000*80,000 = 4,800,000,000).

4.8 billion x 2 nanograms = 9.6 grams (4,800,000,000 * 0.000000002 = 9.6)....and that just about fills 2 tablespoons...

Get it....2 tablespoons of a neonicotinoid could kill every bee in the state of Texas...
