Which of the following real-life scenarios best demonstrates how human activity can reduce biodiversity in an ecosystem?
Deforestation causing species loss
Biodiversity is the variety of species in an ecosystem. Deforestation — clearing forests for farming, timber, mining or settlements — destroys habitat, which is the single biggest human-caused driver of species loss.
When trees are removed, the animals, insects, fungi and plants that depend on them lose food and shelter, populations crash and some species become locally or globally extinct, so biodiversity falls.
Seasonal bird migration, animals moving to a new region and natural succession in a grassland are natural processes, not human activities, and they do not represent human-caused loss of species.
Hence, the answer is: Deforestation causing species loss.
