gathering food instead of cultivating the land for crops
Explanation:
Among the following options that would be least likely to damage an ecosystem is "gathering food instead of cultivating the land for crops."
The gathering of food instead of cultivating the land for crops will not or hardly affect the ecosystem because there is the uprooting of forests or bushes and soils, which are the natural habitats of plants and animals in the ecosystem.
However, founding a new city and building houses there; building a dam to generate electricity; and raising a type of livestock in a region where it is not native will all involve the excavation of soils and clearing of bushes which are natural habitats of plants and animals, thereby affecting the ecosystem.
