What is deforestation?
What is deforestation?
Large-scale removal of trees to repurpose land for agriculture, urban development, or other uses
What is deforested land used for?
What is deforested land used for?
Agriculture, urban development, and other uses
Agricultural causes of deforestation
Agricultural causes of deforestation
Clearing land for cattle ranching and rice fields
Why are biofuels a cause of deforestation?
Why are biofuels a cause of deforestation?
Land cleared to grow crops like sugarcane and maize for biofuel production
Why does deforestation increase CO₂ emissions?
Why does deforestation increase CO₂ emissions?
Trees store carbon; when burned or decomposed, they release CO₂
How does deforestation contribute to global warming?
How does deforestation contribute to global warming?
Releases CO₂ when trees are burned/decomposed, increasing greenhouse gases
How does deforestation affect CO₂ absorption?
How does deforestation affect CO₂ absorption?
Fewer trees means less CO₂ absorbed through photosynthesis
What is the climate impact of reduced CO₂ absorption?
What is the climate impact of reduced CO₂ absorption?
Exacerbates climate change
How does deforestation affect habitats and biodiversity?
How does deforestation affect habitats and biodiversity?
Destroys habitats, reduces biodiversity, endangers species
