What is one of the main causes of species extinction?

Habitat loss is one of the primary causes of species extinction because it directly eliminates the natural environment needed for species to survive and reproduce. When habitats are destroyed or fragmented due to human activities such as urban development, agriculture, or deforestation, the remaining areas may not be sufficient to support viable populations. This leads to loss of food sources, shelter, and breeding grounds, ultimately pushing species towards extinction.

While natural disasters, invasive species, and climate change also contribute to species decline, they often interact with habitat loss in complex ways. For example, invasive species can thrive in degraded habitats, further threatening native species. Climate change impacts can exacerbate habitat loss by altering ecosystems and creating conditions unsuitable for certain species. Therefore, habitat loss stands out as a foundational threat that directly affects biodiversity on a large scale.
