Deforestation Causes & Scale
Understand the causes and scale of rainforest deforestation — cattle ranching (largest driver in the Amazon), soy and palm oil plantations, logging for timber, and mining — and know that approximately 10 million hectares of forest are lost globally each year, with devastating consequences for biodiversity, climate, and indigenous communities
What a learner can do afterwards
- Name at least three major causes of deforestation: cattle ranching, palm oil, soy, logging, and mining
- State that approximately 10 million hectares of forest are lost globally each year
- Explain the impact of deforestation on at least two of: biodiversity, climate, and indigenous peoples
The lesson
You already know the Amazon Rainforest is huge and full of different living things. But every year, people cut down millions of trees there and in other rainforests around the world. It is not just one reason. Four big things drive most of it: raising cattle, growing soy and palm oil, logging for wood, and mining for metals and minerals.
Around 10 million hectares of forest disappear across the globe every year. A hectare is about the size of a soccer field, so picture millions of soccer fields vanishing every year. All together, that is roughly the size of a whole country like South Korea, gone in just twelve months.
In the Amazon, a rancher clears a patch of forest by cutting the trees and often burning what is left. Grass grows in its place, and cattle graze there instead of a living forest. Multiply that one patch by thousands of ranches, and you get a huge chunk of the missing 10 million hectares.
When a rainforest disappears, more than trees are lost. Animals lose their homes, the climate loses a place that stores carbon, and indigenous communities lose land they have lived on for generations.
Rainforests are cut down mostly for cattle, crops like soy and palm oil, logging, and mining, and the world loses about 10 million hectares every year, hurting wildlife, climate, and the people who call the forest home.
