Question

31. Which of these is not a source of increase in carbon footprint?
a. Energy production
b. Deforestation
c. Cycling
d. Sports cars
Answer​

Answer 1

Humans contribute an increase of carbon dioxide emissions by burning fossil fuels, deforestation, and cement production. Methane (CH4) is largely released by coal, oil, and natural gas industries. Although methane is not mass-produced like carbon dioxide, it is still very prevalent.

Answer 2

Option c. Cycling is not a source of increase in carbon footprint.

Carbon footprint can be defined as the amount & level of the carbondioxide gas released into the atmosphere.

In energy production , the energy is generated using burning of coal which definitely emmits carbondioxide with other harmful gases.

In Deforestration , the level of Carbondioxide also increases as the production of oxygen decreases.

In sports car , burning of fuel leads to emmission of carbondioxide.

But where as in cycling it includes manpower so it does not contribute in the increase of the level of the carbondioxide level.
