The two bar charts display data on the number of honey-bee colonies and the amount of honey production in the United States from 1970 to 2010, measured at 10-year intervals.
Overall, the decline in number of honey-bee colonies was generally mirrored by a drop in honey production in most of throughout the period, while 1980 stood out as an exception, with more bee colonies yet less honey product.
As can be seen in the first chart, in 1970, the number of bee colonies stood at 4 million and reached its peak ofat 4.3 million a decade later, before experiencing a continuous decline to its lowest point of 1.8 millions in 2010.
According to the second graphOn the other hand, Iin 1970, honey production was at itsas it highest, reaching 130,000 tonnes, but this figure saw a notable drop to 110,000 tonnes by 1980. A modest rebound occurred in 1990, bringing the output up to 120,000 tonnes. Nevertheless, the final two decades witnessed consistent declines , with production reaching significantly lower levels in 2010 compared to those in 2000.
