deforestation.pptx measures and its causes
- 1. Deforestation “If we lose forests, we lose the fight against climate change” –GCP report
- 2. What is it? Deforestation refers to cutting , clearing and removal of rainforest or related ecosystem into less bio-diverse ecosystem such as pasture, cropland , or plantation. Deforestation is permanent destruction of indigenous forest and woodland s. the term does not include the removal of industrial forests such as plantation of guns or pines.
- 3. Importance Forests play an important role in removing CO2 from the air due to photosynthesises Photosynthesis is a carbon sink Carbon sink : any process that takes CO2 and stores it. Forests need to remain intact or else the atmosphere will have too much CO2
- 4. Types There are 4 different types of Deforestation: i) Natural reasons (i.e volcanic eruption) these reasons are only occur for a small fraction ii) Land clearing to prepare for crops to be planted iii) Commercial logging and timber harvests iv) Slash and burn forest cutting for subsistence farming
- 5. Causes 1. Logging 2. Mining 3. oil and gas extraction 4. Cattle ranching 5. Agriculture: Cash Crops. 6. Local, National, and International factors: development, land titles, government subsidies to attract corporations into developing countries, trade agreements (NAFTA, CAFTA), civil wars, debt, lack of resources, and lack of law enforcement.
- 6. Effects/Consequences Environmental impact 1. Habitat fragmentation. This disturbs the animals' habitat and may force them to enter habitats which are already occupied. This can pose many problems such as territorial conflicts, homelessness (loss of habitat), lack of food availability, migration disturbances, etc.
- 7. Environmental Impact 2. Soil erosion occurs when trees and plants are removed; the rain water washes the nutrients in the top soil away. 3. Climate change (more carbon dioxide is released into the atmosphere, thus increasing the effects of global warming). 4. Pollution (ground, water and air pollution from oil extraction and mining chemicals
- 8. Social impact Social conflicts and struggles over land and natural resources. Conflicts over racial and ethnic rights. Poisoning from oil and mining waste. Economic uncertainty (price fluctuations and high interest rates on outstanding international loans with The World Bank and International Monetary Fund.
- 9. Climate Change Deforestation has a huge impact on global warming Causes 20% of the greenhouse gas emissions – more than all the automobiles in the world combined One of the main causes of climate change 2 million tons of CO2 enters the atmosphere because of deforestation (audit 2003)
- 10. Solutions Corporations/Markets They can use forest products wisely Implement paper saving laws and policies Politics Politicians can implement national laws to help achieve zero deforestation Consumer Power As a consumer we can pressure the companies to implement paper saving laws and policies and be more eco friendly
