Human activities largely influence the concentration of atmospheric carbon dioxide.Since the Industrial Revolution, the atmosphere has experienced an increase in carbon dioxide by 48%.

Consequently, the greenhouse effect has increased, and climate change is inevitable.

Most green plants conduct primary production to produce their food. During this process, they use sunlight and atmospheric carbon dioxide. It implies that this process does not contribute to increasing atmospheric CO₂.

Thus, the worldwide primary production does not increase CO₂ in the Earth鈥檚 atmosphere.

Therefore, the given statement is false.

Increased standing crop implies a more significant number of plants and hence increased primary production. Consequently, there would be increased CO₂ consumption.

Thus, increased worldwide standing crop increases CO₂ consumption and is not the cause of its increase.

Therefore, the given statement is false.

Infrared radiation absorption by the atmosphere gets influenced by the atmospheric CO₂level. Increased absorption of radiation is not a cause but a result of increased CO₂levels.

Thus, increased infrared radiation absorption is a result of increased CO₂.

Therefore, the given statement is false.

Over the years, increased population resulted in increased energy demand and hence fossil fuels and wood. The product of the burning of wood and fossil fuels is CO₂.

Burning more of these resources produces more CO_2, and consequently, its levels increase in the atmosphere.

Thus, burning fossil fuels and woods has increased atmospheric CO₂.

Therefore, the given statement is true.
