Deforestation reduces photosynthetic oxygen production while diminishing major terrestrial carbon sinks, elevating atmospheric carbon dioxide. It further accelerates severe topsoil erosion, decreases transpiration rainfall and destroys wildlife biodiversity.

(i) Impacts on carbon and oxygen cycles: Clearing forests reduces atmospheric oxygen replenishment via photosynthesis and eliminates critical carbon sinks, leaving excess carbon dioxide to accumulate and accelerate global warming. (ii) Broader environmental consequences: Deforestation disrupts regional water cycles by reducing transpiration, accelerates destructive topsoil erosion due to the absence of binding roots and causes severe biodiversity loss.
