Deforestation

Mining: A significant cause of deforestation.
- Environmental impacts include:
  - Soil erosion
  - Formation of sinkholes
  - Loss of biodiversity
  - Contamination of soil and water (groundwater and surface water).
- Mining extracts precious metals and gemstones, affecting tropical rainforests.
  - Examples: Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite, iron ore, gold, silver, diamonds.

Major contributors to paper production include America, China, Japan, and Canada.
- Together, they account for over 400 million tons of paper annually.
Approximately 640 million trees are discarded as paper waste each year.
- Recycling can save about 27.5 million tons of CO2 emissions.
- Using recycled paper preserves forests as ecosystems and habitats.

Growth in population increases the need for land for housing and infrastructure:
- More roads and highways are constructed.
Increased demand for food leads to deforestation for agriculture:
- Trees are logged for products like furniture and building materials.
- Importance of purchasing from sustainable companies to combat deforestation.

Industries reliant on wood include:
- Paper, matchsticks, furniture, etc.
Significant fuelwood use contributes to illegal logging:
- Commonly used for cooking and heating.
Logging sites require road construction, causing further forest clearance.
- Selective Logging: Trees selectively felled, yet surrounding ecosystem is still impacted due to depleting the forest canopy vital for housing wildlife and protecting the ecosystem.

Agricultural practices drive deforestation:
- High demand for palm oil and soybeans prompts forest clearance at alarming rates.
Slash-and-burn techniques degrade soil, forcing farmers to move and clear new areas repeatedly.
- Cattle ranching linked to significant forest loss; Latin America sees nearly a 40% decrease in forests over 40 years due to pasture expansion.

Forests act as carbon sinks, taking in CO2 and releasing oxygen:
- Deforestation results in increased CO2 emissions and impacts climate.
Cutting forests decreases humidity, leaving remaining vegetation more vulnerable:
- Leads to higher risks of fires, both accidental and deliberate.

Trees mitigate greenhouse gas emissions; once removed or burned, they become sources of carbon.
Deforestation accounts for around 20% of global greenhouse gas emissions.
Annual release of 1.5 billion tons of carbon attributed to tropical deforestation.

Increased CO2 levels from deforestation and fossil fuel consumption acidify oceans:
- Oceans have become 30% more acidic since the Industrial Revolution, risking marine species and ecosystems.

Many endangered species (e.g., orangutans, giant pandas, rhinos, Asian elephants) suffer from habitat loss due to deforestation.
Thinning of the forest canopy disrupts temperatures, harming plants and animals:
- Species face decreased habitats and food sources, potentially leading to extinction (e.g., white-cheeked spider monkeys due to expanded farmland).
Water pollution from mining and agriculture exacerbates the situation for endangered species like the giant otter.

Loss of tree coverage leads to soil erosion and increases risks of land degradation:
- Sacred lands and agriculture can be swept into rivers.
Degraded soils lead to decreased water quality and disruption of local water cycles.
Trees play vital roles in water purification and water retention through root systems.

Many people rely on forests for sustenance and materials:
- Includes hunting, small-scale agriculture, and gathering.
Deforestation negatively impacts livelihoods:
- Seen in Southeast Asia where it leads to social conflicts and migration.
Reports of exploitation in Brazilian soy plantations highlight the human cost of deforestation.
