A community heavily relies on forest resources for its economic activities. How does deforestation most significantly and directly impact this community?
- By increasing the amount of available land for habitation and farming.
- By undermining their ability to sustain their livelihoods. (correct)
- By enhancing soil fertility for agricultural purposes.

Study Notes
- Deforestation is the elimination of trees and forest areas, intentionally by people and through natural events.
- Commercial reasons, such as raising livestock, creating agricultural farms, and obtaining timber, drive deforestation.
Biodiversity and Deforestation
- Biodiversity refers to the array of life forms in an area, including various species and ecosystems.
- Deforestation threatens biodiversity by eliminating the habitats of numerous species.
- Forests cover over 30% of the world's land and house approximately 80% of land-dwelling species.
- Deforestation can lead to species extinction if they cannot find a suitable new habitat.
Environmental Impact
- Forests reduce air pollution and produce oxygen.
- Forests act as natural rainwater filtration systems and carbon sinks.
- Deforestation contributes to greenhouse gas emissions, accounting for nearly 20% of the total.
Effects of Deforestation
- Deforestation results in:
- Threatened biodiversity.
- Damaged ecosystems.
- Impaired water quality.
- Worsening droughts.
- Increased greenhouse gas emissions.
- Loss of work for people.
- Impaired soil quality.
- Contribution to climate change.
- Deforestation worsens water quality, increases land and air temperatures, and intensifies drought.
- Deforestation damages soil quality, increasing the risk of erosion and natural disasters like mudslides and landslides.
- Desertification is when previously fertile land becomes perpetually impaired due to depleted soil, drought, and climate change.
Causes of Deforestation
- Natural causes of deforestation include forest fires, parasites, disease infestations, storms, and tornados.
- Human causes of deforestation:
- Agriculture.
- Construction.
- Urbanization.
- Mining.
- Clearing forests for crops and livestock can lead to decreased agricultural productivity in the long run.
- Urban expansion and construction require wood, leading to deforestation.
Deforestation Examples
Amazon Rainforest
- The Amazon rainforest is deforested for livestock and agriculture, impacting biodiversity, carbon storage, and oxygen generation.
- Escalating meat consumption increases the need for livestock generation, contributing to deforestation.
- Approximately 17% of the Amazon rainforest has been deforested in the last half-century.
- Soil erosion, habitat destruction, pollution, and hotter temperatures result from deforestation in the Amazon.
Indonesia
- Deforestation in Indonesia is primarily linked to palm oil production in regions like Sumatra and Kalimantan.
- Tropical forests are cleared for palm oil used in food, makeup, and cleaning solutions.
- Burning trees after removal releases significant amounts of carbon dioxide.
Africa
- The Democratic Republic of Congo contains the planet's second-largest rainforest, facing deforestation from cocoa, palm oil, and mining.
- Western Africa, including Côte d'Ivoire and Ghana, experienced significant deforestation between 2001 and 2014 for cocoa growth.
Deforestation Solutions
- To combat global warming and climate change:
- Develop sustainable farming techniques.
- Promote agroforestry.
- Replant trees and reforestation efforts.
- Buy wood products generated through sustainable practices.
- Limit consumption of products containing palm oil.
- Consume less meat.
- Reduce overall consumption of products.
- Limit paper usage.
- Choose products made from recycled paper.
- Sustainable farming uses less land, reducing the need for deforestation.
- Agroforestry integrates trees into agricultural production.
- Reforestation and planting new trees can help restore lost forests.
- Reducing meat and palm oil consumption can combat deforestation.
- Using recycled paper products reduces the demand for tree felling.

Description
Deforestation involves clearing forests, often for agriculture and logging. This threatens biodiversity by destroying habitats and causing species extinction. Deforestation also impairs air quality and increases greenhouse gas emissions, disrupting ecosystems.
