How have human-induced disturbances impacted terrestrial ecosystems?
Through changes in land use
Terrestrial ecosystems are land-based ecosystems such as forests, grasslands and deserts. The biggest human-induced disturbance to them is change in land use: clearing forests for farming, grazing, mining, roads and cities.
Land-use change destroys and fragments habitats, causes loss of biodiversity, increases soil erosion, alters local water cycles and releases stored carbon into the atmosphere.
Increased vegetation growth is not the main impact of human disturbance; rising ocean temperatures affect marine ecosystems, not land ecosystems; and human activities have increased, not decreased, atmospheric CO2.
Hence, the answer is Through changes in land use.
