Human-environment interactions is the intercations between the human social system and the ecosystem.
One example could be that the people in rural depends on the natural resources,such as the soil,land,and animals to farm,build facilities and hunt to sustain livelihood. Resources taken from the ecosystem are used, however one does not simply carry on like that. For instant when there is excessive cultivation, the soil nutrient would be used up causing soil erosion,leading to the soil no longer fertile enough to farm. Therefore,measures are carry out to preserve the land like growing different crops and using fertilizer.
Hope it helps!

An area of forest is clear cut.
