What is depletion of forest?
The depletion of the forest is called deforestation. Over the years, the area under forest cover has decreased steadily, as forests have been cleared for agriculture, industry, housing, and other development activities like the construction of roads, railways, and hydroelectric plants.
How depletion of forests affect the ecosystem?
Deforestation can be defined as the large-scale removal of trees from forests (or other lands) for the facilitation of human activities. It is a serious environmental concern since it can result in the loss of biodiversity, damage to natural habitats, disturbances in the water cycle, and soil erosion.
What causes depletion of forests?
The most common pressures causing deforestation and severe forest degradation are agriculture, unsustainable forest management, mining, infrastructure projects and increased fire incidence and intensity.
How does deforestation lead to ecological imbalance?
Deforestation creates imbalance in nature by reducing the amount of oxygen and increasing the amount of carbon dioxide. when trees are cut due to the process of deforestation there are less trees in the environment to absorb carbon dioxide from the atmosphere for the process of photosynthesis.

What are the causes of depletion of forest Class 9?
Causes of Deforestation
- Agriculture. The conversion of forests into agricultural land is one of the major causes of deforestation.
- Rapid growth in the industries.
- Forest fires.
- Global warming.
- Soil erosion.
- Loss of biodiversity.
- Climatic change.
How do forest impact the ecosystem?
Forest improves the environment in many ways such as: Relative humidity of air is increased. increase fertility of surface soil. These add large quantities of organic matter in soil by which water and nutrient holding capacity of soil is increased.
What is the effect of forest on the environment?
Forests cover about a third of the earth’s land area and are essential to the health of our environment. For example, trees and forests absorb and store much of the carbon dioxide that otherwise would be contributing to climate change. Forests are home to about 80 percent of remaining terrestrial biodiversity.
What is ecological imbalance?
When a natural or human-caused disturbance disrupts the natural balance of an ecosystem it is known as Ecological imbalance. This disturbance is any change that causes a disruption in ecosystem balance.
What are the causes of ecological imbalance?
Ecological Imbalance in India: 5 Main Factors
- Degradation of Land and Soil Erosion:
- Faulty Utilisation of Water Resources:
- Environmental Problems from Faulty Mining Practices:
- Industrial and Atmospheric Pollution:
What are the causes of forest depletion in India?
Rapid Industrialization, urbanisation and expansion of cities has also led to the destruction of forest cover in the country. Animal grazing, mining, collection of fire wood in rural areas are some other reasons of forest depletion in the country.
What are the various causes for the depletion of forest and wildlife resources class 10?
- Mining,grazing,development projects have contributed to the loss of forests.
- Forests provide us with wood,barks,leaves,rubber hence leading to depletion of the forest by human being.
- Expansion of railway,agriculture,commercial and scientific forestry and mining activities have caused greatest damage.
Which factors affect the depletion of forest Class 7?
- Deforestation ( cutting of trees )
- Poaching of animals for their skin.
- Urbanization and increase in population.
What are the problems of forest ecosystem?
Forests have long been threatened by a variety of destructive agents. Today, the frequency, intensity and timing of fire events, hurricanes, droughts, ice storms and insect outbreaks are shifting as a result of human activities and global climate change, making forest ecosystems even more prone to damage.
What are the effects of forest destruction?
The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.
What are the role of forest in maintaining ecological balance?
Forest helps in cleaning the environment by absorbing toxic gases like carbon. They help to prevent soil erosion and uphold the fertility of the soil. They help to establish oxygen and carbon balance in nature, and hence, the forest is essential for maintaining an ecological balance.
What is the harmful effect of forest?
The adverse effect caused by the operations of forest industries include loss of biodiversity, migration of wildlife, ecological imbalance, soil erosion, flooding, desert encroachment and disruption in hydrological cycle of water catchment area.
What are the effect of ecological imbalance?
Pollution (air, water and soil) Degradation of natural resources such as soil erosion, deforestation, depletion of wildlife, shortage of energy, degradation of marine ecosystems and depletion of mineral resources.
What is ecological imbalance explain?
Ecological imbalance is when a natural or human-caused disturbance disrupts the natural balance of an ecosystem. A disturbance is any change that causes a disruption in the balance of an ecosystem. Examples of natural disturbances are. Volcanic eruptions.
What are the three main causes of depletion of forest in India?
What are the reasons for depletion of forests?
This article throws light upon the eleven main reasons for depletion of forests. The reasons are: 1. Human Settlement 2. Conversion into Arable Land 3. Lumbering 4. Development Projects 5. Jhum Cultivation and Fuel Wood Collection 6.
Does deforestation cause ecological imbalance and lead to environmental deterioration?
“Deforestation causes ecological imbalance and leads to environmental deterioration”. Discuss in reference to Forest Conservation Act, 1980. An Act to provide for the conservation of forests and for matters connected
How does the absence of trees affect the ecological cycle?
It means the absence of trees can influence the quantity of water on the land, in the atmosphere or in the soil. It affects the ecological cycle. Soil – Forests as such have a very low soil loss rate.
What will happen to the world’s poor if forests are destroyed?
Damage to forests and other aspects of nature could halve living standards for the world’s poor and reduce global GDP by about 7% by 2050, a report concluded at the Convention on Biological Diversity (CBD) meeting in Bonn in 2008.
