The U.S.
Food and Drug Administration has approved few of these medications for the preschool age group, yet
previous studies documented two to threefold increases in psychotropic
prescriptions for preschool children between 1991 and 2001.
The results of this model - based study fall in line with the
previous work of Idso (2013), who calculated similar CO2 - induced benefits on global crop production by mid-century based on real - world experimental data, both of which studies reveal that policy
prescriptions designed to limit the upward trajectory of atmospheric CO2 concentrations can have very real, and potentially serious, repercussions for global
food security.
