Which do many scientists condsider the number one cause of extinction?

Many scientists consider habitat loss and degradation to be the number one cause of extinction. This is primarily driven by human activities such as deforestation, urbanization, and agriculture, which destroy or fragment natural habitats. As ecosystems are altered or eliminated, the species that depend on them struggle to survive, leading to declines in biodiversity and increased extinction rates. Climate change and pollution also contribute to this crisis, but habitat loss remains the most significant factor.
