Name a major threat to biodiversity.

Climate change is a significant threat to biodiversity because it alters the natural habitats and ecosystems that species depend on for survival. Changes in temperature and precipitation patterns can lead to habitat loss, shifts in species distributions, and increased vulnerability to diseases and invasive species. This affects not only individual species but also the complex interactions in ecosystems that maintain balance and diversity. When species cannot adapt quickly enough to the changing conditions, it can result in population declines or even extinction, thereby reducing overall biodiversity.

In contrast, increased soil fertility is generally beneficial for plant growth and can enhance ecosystems, while public awareness initiatives and environmental restoration projects often aim to protect and promote biodiversity rather than threaten it.
