I want to know the answer to the following question:
On estimate how many megatonnes of pesticides were used between 2006 and 2007?
All the background I'm provided with is that "As of 2007, there were more than 1,055 active ingredients registered as pesticides, which yield over 20,000 pesticide products that are marketed in the United States.". Is that enough to answer the question?
Answer: no
