1. Complete Activity 5.1 (Page 53). Add more causes of deforestation to your list and classify them into natural and man-made.
Answer:
Other natural causes of deforestation:
Climate Change: Changes in the climate over time such as substantial increase in temperature and altered level of precipitation can lead to deforestation.
Soil Erosion: Flooding can lead to soil erosion, which in turn can lead to loss of vegetation and gradual deforestation.
Plant Disease: Certain strains of plant diseases may result in widespread death of trees and hence, deforestation.
Volcanic Eruptions: Since prehistoric times many forestshave been buried under lava due to volcanic eruptions.
Pest Outbreaks: Certain pests can carry out large scale deforestation.
Other man-made causes of deforestation:
Mining Activities: Mining operations for minerals and fossil fuels are carried out in many places and deforestation is carried out to make way for these.
Cattle Ranching: Many forests have been cleared to make space for raising cattle.
Building Dams and Reservoirs: When dams and reservoirs are built, entire forests are wiped out.
Building Roads and Highways: Deforestation happens when huge roads and highways are built by clearing of forests.
Pollution: Industrial emissions and effluents released into the air and water can affect the growth of plants and even destroy existing vegetation. This may cause deforestation.
