<u>Question</u>:
Which activity produces the smallest amount of greenhouse gases?
a. driving a car
b. riding a bicycle
c. cooking with gas
d. operating a generator
<u>Answer</u>:
Riding a bicycle produces the smallest amount of greenhouse gases
<u>Explanation</u>:
Cars and other heavy vehicles account for approximately 1/5th of the United States emissions, producing carbon dioxide and other greenhouse gases such as methane and nitrous oxide. Cooking gas too produces a lot of carbon dioxide. Natural gas too basically consists methane in an odourless form and therefore when released produces greenhouse effects and in turn causes detrimental effects on the environment.
The generators that are used both at low scale and also in high level industries is known to produce toxic levels of carbon monoxide and methane. Compared to all these, a bicycle which produces greenhouse gases during its production does not release as much greenhouse gases and the rest.
