Practice AP Environmental Science questions on meat-production efficiency, CAFOs, free-range grazing, overgrazing, desertification, and impacts.
The graph below is from the United States Department of Agriculture website.
What could be a reason for the trend in the graph from 1996 to 2015?
As demand for beef increased, ranchers bred more cattle.
As drought conditions increased, ranchers slaughtered their cattle.
The supply of domestic pork decreased.
Ranchers began to use concentrated animal feeding operations (CAFOs) rather than free-range cattle farming.
The following graph shows how global uses of habitable land have changed since 1700.
Land Use Changes on Earth, 1700-2018
Based on the data in the graph, describe the relationship between the land use changes in the wild grasslands and grazing from 1700 to 1950.
Identify an environmental problem associated with overgrazing by livestock.
