5. Carbon monoxide emissions: a) In 2021, forest fires burned 2.57 million acres in California. Using estimates of 80 metric tons of forest biomass per acre (US forest service) and 89 g CO emitted per kg forest biomass burned (Akagi et al., 2011), how much CO was emitted from forest fires in California in 2021? b) Compare the CO emissions from biomass burning to those from vehicles, using estimates of 54 g CO emitted per kg fuel burned (Park et al., 2011) and 58 million gallons of fuel (gasoline + diesel) burned daily in California (US EIA). What are the policy implications for California's ability to control CO pollution, and particularly to reduce human exposure to elevated CO events
