Final answer:
The transition from foraging to farming had both positive and negative effects on the environment. It led to a loss of biodiversity, the dispersal of species, and environmental degradation in certain regions.
Step-by-step explanation:
The transition from foraging to farming had both positive and negative effects on the environment.
- Loss of biodiversity: As early humans domesticated specific plant and animal species, they focused on increasing the local concentrations of edible species. This led to a loss of biodiversity as species with little or no food value were reduced in concentration.
- Dispersal of species: Agriculture resulted in the dispersal of plant and animal species, not just locally, but also across the world. The invasion of the Americas by Europeans played a significant role in this global dispersal of species.
- Environmental degradation: In some regions, farming led to a loss of productivity due to factors like soil erosion and salinisation, resulting in a negative impact on the environment.
