wildfires, overgrazing, logging, non-native species
Explanation:
- Many factors can affect the north American biodiversity and forest as the introduction of the invasive species by the man himself as these species tends to raise the competition with the primitive species and they increase the demand for respect and thus pressurize the lands and often leads to the elimination of the native species.
- Wildfires are also one of the biggest factors of the damages and the destruction to natural forests wither by the man or nature proves to be dangerous for the human population and also for the species of flora and the fauna that live in those zones.
- The impact pf overgrazing also leads to loss of the mineral contains form the soil and the soil becomes prone to weathering and thus erosion takes the place and washes away the soil and the fertile humus layers and thus leading to the degraded soil and not fit for the cultivation of the crops.
- The logging which is considered to an illegal activity is also very harmful to the native trees and the forest lands as it destroys the ecological balance and the majority of species habitat loss.
