Question

Give any two causes of biodiversity loss.

Hint:

Remember: Habitat destruction and overexploitation are the two primary drivers of biodiversity loss globally.

Answer 1

Biodiversity loss refers to the decline or disappearance of species, ecosystems, or genetic diversity on Earth. Two major causes are: \begin{enumerate} \item Habitat Destruction: The clearing of forests for agriculture, urbanization, mining, and infrastructure development leads to the loss of natural habitats. This directly reduces the living space for species, pushing many towards extinction. Example: Deforestation in the Amazon rainforest has caused severe habitat loss for countless species. \item Overexploitation: Unsustainable hunting, fishing, logging, and harvesting of plants and animals have led to a drastic decline in many species. Overexploitation disturbs ecological balance and reduces population sizes beyond recovery. Example: Overfishing has led to the collapse of several marine fish populations. \end{enumerate} Other Causes (for reference): Climate change, pollution, invasive alien species, and diseases also significantly contribute to biodiversity loss.
