"STOCKTON, Calif — Work began in the dark. At 4 a.m., Briseida Flores could make out a fire burning in the distance. Floodlights illuminated the fields. And shoulder to shoulder with dozens of others, Ms. Flores pushed into the rows of corn. Swiftly, they plucked. One after the other. First under the lights, then by the first rays of daylight.
By 10:30 a.m., it was unbearably hot. Hundreds of wildfires were burning to the north, and so much smoke was settling into the San Joaquin Valley that the local air pollution agency issued a health alert. Ms. Flores, 19, who had joined her mother in the fields after her father lost his job in the early days of the coronavirus pandemic, found it hard to breathe in between the tightly planted rows. Her jeans were soaked with sweat.
“It felt like a hundred degrees in there,” Ms. Flores said. “We said we don’t want to go in anymore.”
She went home, exhausted, and slept for an hour."
