Human activities, such as the burning of fossil fuels, result in air pollution. what could be an outcome if the amount of smoke released is not regulated? a) sunlight would not be able to reach earth. b) the temperature of the region would decrease. eliminate c) trees would begin to die, leading to habitat loss. d) the smoke would settle around cities, reducing visibility.

More than one of these could be an answer because D could be correct (it could create smog in areas like cities) C could be correct (the trees would die due to more carbon monoxide released in the air that they breathe) and B could be almost be correct the temp. of a region would increase because the greenhouse gasses would destroy the ozone layer and ultra violet rays would fry the Earth. (sorry if it wasn't helpful or it was confusing)

Ihaven't done that yet, so no idea,but this is not the right place to ask
