What human activity has had the least effect on the biosphere?

Answer 1

Among various human activities, traditional subsistence farming practices tend to have the least impact on the biosphere. These methods often prioritize sustainable land use, rely on local resources, and maintain biodiversity by rotating crops and using organic techniques. Unlike industrial agriculture, which can lead to deforestation, soil degradation, and loss of habitats, subsistence farming typically supports ecological balance and community resilience. However, even these practices can accumulate negative effects if scaled up or altered significantly.
