Final answer:
Massive land clearing has several negative impacts on the environment, including habitat destruction, deforestation, erosion, and pollution.
Step-by-step explanation:
When massive amounts of land are cleared, it leads to significant environmental consequences. Habitat destruction is the most obvious impact as it destroys the homes of many plants and animals. This loss of habitat can result in the extinction of species and disrupt entire ecosystems. Land clearing also contributes to deforestation, desertification, erosion, and pollution, leading to a loss of biodiversity and degradation of natural resources.
