Because of the growing health crisis of antibiotic resistance, which could render
these “wonder drugs” useless in treating infections, the American Medical
Association now opposes the routine feeding of antibiotics to healthy farm animals.
The American College of Preventive Medicine, the American Public Health
Association, and the World Health Organization have taken similar positions.
A National Academy of Sciences report estimates that eliminating all such uses
in poultry, cow, and swine production would cost US consumers only about $5
to $10 per person annually. The Centres for Disease Control and Prevention has
observed that “decreasing inappropriate antibiotic use is the best way to control
resistance.” Key steps in doing so include adoption of policies aimed at ending the
inappropriate use of antibiotics in agriculture, as well as continued implementation
of programs to educate patients, parents and physicians about the need to
use antibiotics more sparingly.
HIV and Climate Chang Complex
They argued that the widespread food crisis in sub Saharan Africa (SSA) in the
early 2000s could not be fully explained by the region’s periodic droughts (whether
or not the frequency or severity of these droughts is changing). Instead, they
proposed the high prevalence and incidence of HIV as an overarching reason to
explain these changes. They suggested that the AIDS epidemic accounts for why
many households are facing food shortages and have difficulty recovering from
droughts. They identified four new factors: (1) household level labour shortages
due to adult morbidity and mortality and a rise in numbers of dependants; (2)
loss of assets and skills resulting from increased mortality; (3) the burden of care
for sick adults and children orphaned by AIDS; and (4) vicious interaction exists
between malnutrition and HIV. We agree that these feedbacks and links are
highly plausible connections between HIV, regional agricultural productivity, and
regional food security.
According to the IPCC, there have also been several important climatic changes
in SSA in recent decades. These include increased inter-annual rainfall variability
since 1970, with higher rainfall anomalies and more intense and widespread
droughts. In some parts of southern Africa (e.g., Angola, Namibia, Mozambique,
Malawi and Zambia) a significant increase in heavy rainfall events has also been
observed together with evidence for changes in seasonality and weather extremes.
These changes are consistent with anthropogenic CC, and it is likely that these
trends will intensify. Thus, while much of the recent deterioration in food security
