Question

1. figure 3 shows the effect of human population on the amount of carbon dioxide in the atmosphere. why would deforestation, combined with burning of fossil fuels after the industrial revolution, cause more carbon dioxide to be in the atmosphere? figure 3. the effect of global population on global carbon dioxide released global co2 emissions (mmtc)

Explanation:

Step1: Analyze human - related factors

Deforestation reduces the number of trees that absorb carbon dioxide. Burning of fossil fuels after the industrial revolution releases a large amount of carbon dioxide stored in fossils into the atmosphere.

Step2: Relate to the carbon - cycle impact

These human activities disrupt the natural carbon - cycle balance, leading to an increase in the amount of carbon dioxide in the atmosphere.

Answer:

Deforestation reduces carbon - dioxide absorbers (trees), and burning of fossil fuels releases large amounts of stored carbon - dioxide. This combined effect causes more carbon dioxide to be in the atmosphere as it disrupts the natural carbon - cycle balance.
