Answer:
Large amount of reduction occurs.
Explanation:
Large amount of reduction occurs in the harmful emissions if the family used public transportation for school and work, used energy-efficient lightbulbs in your house, switched to a vegetarian or vegan diet, etc because these activities produces large amount of carbondioxide gas. 36.44 billion metric tons of carbondioxide gas is produced per year due to human activities so due to reduction in emission about 12 billion metric tons of carbondioxide is produced which is 1/3 of the total emission. these steps can neutralize carbon footprint emissions because only the nature emitted carbondioxide gas in the atmosphere which create balance on the earth.
