What are the major cause of deforestation?
Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. Most often, multiple processes work simultaneously or sequentially to cause deforestation.
What are the consequences of deforestation Class 7?
There are several consequences of deforestation:
- Changes in Soil: Loss of nutrients in the soil that are derived from breakdown of tree leaves. Increased soil erosion by wind and rain.
- Loss of biodiversity: Animals and plants that are unable to grow outside of a forest environment face extinction.
- Climate change:
How many trees are cut down every year 2020?

What makes a jungle a jungle?

They’re dangerous places, even for the animals that live there. This is why jungle also means any place that is risky or wild.
