Some parts of the Earth's surface have been affected more profoundly by human activities than other parts, but all parts have been affected to some degree, so my answer is 100%.

Approximately 75% of the Earth's land surface has been significantly altered by human activities, including deforestation, agriculture, urbanization, and mining. This high level of human impact has led to habitat loss, degradation, and fragmentation, threatening biodiversity and ecosystems across the globe.
