question 11 of 20
which of these human activities is most likely to cause an increase in the number of cases of heat exhaustion among humans?
a. use of hair spray containing chlorofluorocarbons
b. burning of plastics in open burn barrels
c. use of solar panels instead of fossil fuels for energy production
d. increased consumption of beef, which increases methane production

Explanation:

Burning plastics in open - burn barrels releases heat and pollutants into the environment. This can increase local temperatures and contribute to air pollution, making it more likely for people to experience heat exhaustion. Hairspray with chlorofluorocarbons affects the ozone layer, solar panels are a clean energy source, and increased beef consumption affects methane levels but not directly heat exhaustion in the same way as open - burning plastics.

Answer:

B. Burning of plastics in open burn barrels
