Describe Mangrove Forests
These are mainly found in Sundarban in Khulna. The sundari trees are mainly found in these forests which is why there is the name Sundarban. These trees are commercially valuable as they are used in bridge building and other construction purposes
Why are forests so important
They play a key role in providing locals with consumable products. They also contribute to protect the natural environment (In BD), by helping to stabilize the soil and giving protection from river erosion. Forests also provide a natural barrier in times of disasters.
What is deforestation and why must it occur
Deforestation is the large scale removal of trees from forests because of the increasing population which leads to the greater need for land (for agricultural, housing and industrial purposes) and demand for timber and fuel.
What should the government do to prevent deforestation
They should enforce strict laws so that people are discouraged to not cut down trees and instead organise events to plant more trees.
