A large-scale project is initiated to plant millions of trees in a previously barren area. Over several decades, what is the most likely effect on the global carbon equilibrium?

It will shift the equilibrium, reducing atmospheric CO₂.

It will have no effect on the carbon equilibrium.

It will increase atmospheric CO₂ due to plant respiration.

It will cause a permanent decrease in the total amount of carbon on Earth.

How does a major change in land use, such as converting a forest to a cattle ranch, primarily affect global climate trends?

It increases the Earth's reflectivity, causing a net cooling effect.

It directly destroys the ozone layer above the affected area.

It reduces the planet's capacity for carbon fixation, increasing atmospheric CO₂.

It primarily alters local water cycles with no significant impact on global climate.

Removing organisms that convert atmospheric CO₂ into biomass disrupts the carbon cycle's balance.

The decay of dead trees consumes vast amounts of atmospheric oxygen, which unbalances the atmosphere.

Forests are dark and absorb sunlight, so removing them reflects more sunlight and heats the atmosphere.

Deforestation primarily affects water cycles, which then indirectly leads to an increase in CO₂ levels.

Developing more efficient solar panels.

Protecting marine life in the deep ocean.

Implementing large-scale reforestation programs.

Building taller smokestacks for industrial factories.

The release of carbon from decaying plant matter into the soil.

The conversion of atmospheric carbon dioxide into organic compounds by plants.

The process by which animals release carbon dioxide through respiration.

The burning of wood, which releases stored carbon back into the air.
