It is best to say that most human sources of air pollution result from
a.
forestry management
b.
fuel burning
c.
heating devices
d.
vehicle exhaust

Answer : The correct option is, B.

Explanation :

Fuel burning : When the fuel burns, the carbon and hydrogen atoms combine with oxygen atoms to produce carbon dioxide and water vapor.

The burning of fuels like wood, coal and petroleum products releases unburnt carbon particles in the air. These unburnt carbon particles are the harmful pollutants which can cause respiratory diseases.

Therefore, the fuel burning is the human source of air pollution.

lol idk man i guess u gotta ask bill nye the science guy

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
