Growing population and the ever-increasing demand of the population are the main causes of large-scale destruction of forests cover and arable land. Let's delve into these factors in more detail.

Growing population:
1. Increased demand for resources: As the population grows, the demand for resources such as food, shelter, and energy increases. This leads to the expansion of agricultural activities and the need for more land for settlement and infrastructure development.
2. Deforestation for agriculture: To meet the growing food demand, forests are cleared to make way for agriculture. This results in the loss of forest cover and arable land.
3. Urbanization: Rapid urbanization occurs as the population increases, leading to the conversion of agricultural land and forests into urban areas. This further contributes to the destruction of natural habitats.
4. Logging and timber extraction: With a larger population, the demand for timber and wood products also increases. This leads to unsustainable logging practices, causing deforestation and degradation of forests.

Ever growing demand of the population:
1. Increased consumption: As the population grows, the overall consumption of goods and services also increases. This puts pressure on natural resources, leading to their overexploitation.
2. Expansion of industries: The growing demand for goods and services results in the expansion of industries. Industries require land for their operations, leading to the conversion of forests and arable land into industrial zones.
3. Mining activities: The demand for minerals and other natural resources for industrial purposes increases with the growing population. Mining activities often result in the destruction of forests and arable land.
4. Infrastructure development: The need for infrastructure such as roads, highways, and buildings also increases with the population. This leads to the conversion of land, including forests and arable land, for construction purposes.

Conclusion:
The combination of a growing population and the ever-increasing demand of the population for resources and goods is responsible for the large-scale destruction of forests cover and arable land. This has severe consequences for the environment, including loss of biodiversity, soil erosion, and climate change. It is crucial to address these issues through sustainable practices, conservation efforts, and population control measures to ensure the preservation of forests and arable land for future generations.
