Ask AI: How would the earth look if no people lived on it

Without people, the landscape of the Earth would look much different than it does now. Many of the human-made features such as buildings, bridges and roads would be gone, replaced by natural features such as forests, grasslands and mountains. The air quality would improve as air pollution from vehicles and factories would be drastically reduced. The seas, rivers, and lakes would be less polluted, allowing aquatic life to flourish. The variety and number of species of animals and plants on the planet would increase as habitats that were once destroyed by humans would be restored. Overall, the earth would be a much healthier and more beautiful place.
