What does homogenization refer to in the context of biodiversity?

Homogenization in the context of biodiversity refers to the process whereby ecosystems and species become more similar to one another, often leading to a loss of biodiversity. This occurs as a result of various anthropogenic factors such as habitat destruction, climate change, and the spread of invasive species, which can cause unique ecosystems to lose their distinctive characteristics and species compositions. When local species are replaced by a limited number of widely distributed species, the overall variety of life decreases. As ecosystems become homogenized, they are less able to support diverse forms of life, which reduces resilience to environmental changes. Thus, the correct answer captures the essence of how homogenization impacts biodiversity through the loss of distinct ecosystems and species.
