What is the main cause of deforestation worldwide?
Explanation: The correct answer is A) Agricultural expansion. The main cause of deforestation worldwide is agricultural expansion, particularly for the conversion of forests into croplands, pasturelands, and plantations. Large-scale commercial agriculture, including cattle ranching and the cultivation of soybeans, palm oil, and other commodities, drives significant deforestation.
What are the environmental consequences of deforestation?
Explanation: The correct answer is D) All of the above. Deforestation has numerous environmental consequences, including the loss of biodiversity and habitat destruction, increased soil erosion and degradation, and the disruption of water cycles. Additionally, deforestation contributes to climate change as forests act as carbon sinks, absorbing and storing significant amounts of carbon dioxide.
What is land use change?
Explanation: The correct answer is C) The transformation of natural ecosystems for human activities. Land use change refers to the alteration of land cover or land use patterns, usually driven by human activities, to accommodate various purposes such as agriculture, urban development, infrastructure construction, and industrial activities. This process often involves the conversion of natural ecosystems, including forests, into altered landscapes.
What are the main drivers of land use change?
Explanation: The correct answer is D) All of the above. Land use change is driven by multiple factors, including population growth, urbanization, economic activities, globalization, and government policies. As populations increase, there is a greater demand for resources and land to support agriculture, housing, and infrastructure, leading to land conversion and deforestation.
What are some strategies to mitigate deforestation and land use change?
Explanation: The correct answer is D) All of the above. Mitigating deforestation and land use change requires a multifaceted approach. Strategies include implementing sustainable land management practices to reduce the environmental impact of agriculture and forestry, promoting reforestation and afforestation initiatives to restore forest cover, and strengthening protected areas and conservation efforts to safeguard valuable ecosystems.
