Climate change increasing food insecurity in San Antonio, other places, HHS official warns

Climate change is likely to worsen food insecurity among the nation's most vulnerable residents, including those in San Antonio, said Admiral Rachel L. Levine, assistant secretary of the U.S. Department Health and Human Services. "The influence of climate change is one of the existential health risks of our time," said Levine, who was in the city Monday for a nutrition-insecurity summit hosted by the San Antonio Food Bank.
