Smoke can come from several things. White smoke when first starting on a cold day is normal. Black smoke indicates the wrong fuel/air mixture. Blue smoke indicates that the engine is burning oil.
what will be the effect on natural resources when cars,trucks,and tricycles that emit dark smokes are allowed to travel
Dangerously heavy air pollution would be one result.
Cars that don't have smoke in them do not let out smoke.
Yes they do.
Many of them do
Both. Cars emit Hydrocarbons + Nitrogen Oxides + Carbon Dioxide + Carbon Monoxide. People emit Methane and Carbon Dioxide.

Internal combustion engines don't emit cloroflorocarbons, but they do emit hydrocarbon's. Hydrocarbons are/is unburned fuel which can be caused by a number of things,but it all leads back to unburned fuel.
coke probably does emit gases, but you dont see them cause they are clear, but it doesnt emit smoke, which i am guessing would refer to carbon dioxide, because burning coke does not create it as one of its products. i am not sure what coke has in it exactly, so if someone can explain better then please do.
