Important Of Forests For The Environment

Important of Forests For The Environment


The forest is home to a variety of living things. It is an incredibly precious natural resource. The species that live in forests are interdependent. Factors including air, water, and sunlight have an impact on forest life. Depending on the environment, most forests feature a wide variety of plants, including herbs, shrubs, and trees. Photosynthesis allows plants to make their own food, whereas animals must obtain their food from both plants and other living things. For tasks like pollination and seed dissemination, plants may also rely on animals. Over vast portions of the world, there exist countless forests. Based on the climate and species of trees present, forests can be categorized as tropical, evergreen, partly evergreen, deciduous, or dry forests. 


•    A forest is a region of land that is covered in trees.
•    In accordance with the United Nations Food and Agriculture Organization, a forest is "land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10%, or trees capable of reaching these criteria in this condition," as well as "trees capable of reaching these criteria in this condition."
•    Land utilized largely for agriculture or urban construction is excluded.
•    According to this definition, the Global Forest Resources Assessment 2020 estimated that the world's total forest lands in 2020 would cover around 4.06 million hectares, or 10 million acres, or 31% of the planet's surface. 


Support Ecosystems and Habitats

•    Millions of creatures find homes in forests, which also support different ecosystems.
•    Forests are home to over 90% of all species on Earth.
•    Forests and the banks of rivers and streams are home to a variety of creatures, including lizards, snakes, turtles, crocodiles, alligators, insects, birds, butterflies, and monkeys.
•    As a result of their interactions in their physical habitats, these species create food chains in the forests, creating an ecosystem.
•    Having a healthy ecosystem is crucial for animal life. Millions of indigenous peoples still reside in the forests and depend on them for their survival.

Protecting watershed regions

•    Since rivers, lakes, and streams as well as water tables derived from the forest serve as the main sources of water in forested areas, forests act as watershed regions.
•    Rivers and streams that flow through forests are shielded from the drying effects of the sun by the forest cover.
•    One of the greatest watersheds and river systems in the world, for instance, is found in the Amazon.
•    Around the world, numerous other forests serve as significant watershed zones.

Maintains biodiversity

•    Genes from biodiversity are stored in forests.
•    This is because forests are home to almost 90% of all plant and animal species on earth, leading to a wide variety of plant and animal life forms in various forest environments.
•    By supplying homes for a variety of plants and animals to thrive in, forests help support biodiversity.
•    Forests are home to some of the most endangered species on earth.

Air Purifier

•    The air we breathe is significantly purified by forests. Trees and plants use photosynthesis during the day to absorb carbon dioxide and release oxygen.
•    Consequently, they aid in purifying the air we breathe.
•    As a result, forests are a crucial instrument for lowering atmospheric concentrations of carbon dioxide and other greenhouse gases that cause global warming.

Climate Stabilizer

•    Forests serve as climate stabilizers because they provide an environmental breeze and employ evapotranspiration to control air temperatures.
•    For instance, the presence of trees in urban areas might reduce the need for air conditioners.
•    The sun's radiant heat is absorbed by large woods, which also promote evapotranspiration, which increases rainfall and a mild environment.

Soil Enrichment

•    Through the loss of leaves and short branches, plants and trees contribute to the recycling of soil nutrients.
•    Additionally, soil is broken down into tiny pieces by plant and tree roots, which improves water infiltration.
•    Additionally, the roots take up some of the water from surface runoff and slow the flow, preventing soil erosion, which reduces the fertility of the soil.

Water Cycle Regulator

•    The natural cycle of water evaporation, condensation, and precipitation in the form of rain is influenced by forests.
•    This is made feasible by trees using a mechanism known as water economics to collect and distribute rainwater fairly equally across their whole geographic extent.
•    Additionally, forests gather a considerable amount of runoff, which they then channel into aquifers to restore groundwater supplies.

Therapeutic Value

•    With their rich variety of plant and animal life, forests have a special relationship with medical advancements.
•    The majority of drugs used in various medical procedures come from animals and plants found in forests.
•    A wide range of miraculous treatments, including cancer-fighting drugs, can be found in forests.

Financial Importance

•    We receive significant economic benefits from forests.
•    Humans receive wood and timber from plantation forests, for instance, which is used for construction and as a raw material for a variety of goods.
•    Furthermore, the host countries and communities profit financially when tourists travel to forest areas to admire the breathtaking landscape and the wildlife that calls them home.
•    Along with unusual species like wild rabbits, forests offer a source of food and vegetables like berries, tubers, and edible mushrooms that grow on forest floors.

Climate Change Factor

•    Trees extract water from the ground and release it into the atmosphere.
•    As a result, vast forests have the power to alter the atmospheric conditions that bring about rain in addition to shaping their own microclimates.
•    The size of the forest can also have a significant impact on weather patterns thousands of miles away.
•    For instance, the weather in the United States is impacted by the Amazon jungle.
•    The effects of climate change are also lessened by standing woods.
•    They control water flows, absorb CO2, and protect coastal areas from severe weather and sea level rise.
•    Additionally, they offer routes for migratory plant and animal species to find habitats that are resilient.

Forest-related dangers

Climate Change

•    One of the most important problems facing the world today is climate change.
•    Forests can help battle climate change, but they are also quite vulnerable to shifting weather patterns.
•    The climate affects the kind of forest that may flourish in a specific area.
•    To cope with a changing climate, forests must adapt. On the other hand, the process of adaptation frequently takes longer than the varying climate conditions permit.
•    As a result, it regularly happens that trees, biodiversity, and the capacity to mitigate the effects of climate change are lost.


•    The biodiversity of forests could suffer significantly as a result of deforestation.
•    According to estimates from the UN Food and Agriculture Organization (FAO), deforestation will result in the loss of 13 million hectares of forest year.
•    Some tropical forests might need a thousand years to recover their richness, but others have already suffered irreparable damage as a result of species extinctions brought on by habitat degradation.
•    Agriculture is commonly acknowledged as the principal driver of deforestation because forests are destroyed to make place for farmland or ranches for cattle.

Disturbances and Natural Disasters

•    Together with climate change, natural disturbances hasten the further deterioration of forests.
•    As a result of climate change, invasive plant and insect species are outperforming native species.
•    Most forest pests have been kept at bay so far by winter freezes, but warmer temperatures will aggravate their negative effects on forests.
•    Because they can survive extreme conditions, invasive plant species will be able to multiply and spread, and harmful insects will take advantage of drought-damaged woodlands.


•    We can appreciate the significance of forests in our life once we have this insight.
•    The loss of green cover on the planet's surface must be regulated and deforestation must be stopped.
•    Let's look at several options for preserving the woodlands.

Controlled Deforestation

•    Deforestation cannot be stopped, but it can be controlled.
•    Trees that are young or immature should be avoided whenever feasible.
•    We must also look for ways to stop widespread commercial deforestation.
•    In the long run, adopting techniques like clear-cutting or selective cutting will be advantageous.

Security from forest fires

•    Forest fires are the most frequent and deadly reason for forest loss.
•    They may appear as a result of natural calamities, accidents brought on by people, or, in certain circumstances, deliberate intent.
•    A forest fire is extremely challenging to put out after it has spread. There must be safety measures in place in the case of such an occurrence.
•    Making fire lanes, dousing areas with fire retardants, raking up dead leaves and branches, etc.


•    This is the method we use to increase the amount of trees in a specific location.
•    By manually moving trees or planting new ones, we try to enhance the amount of forest cover.
•    It is an effort to restore equilibrium to our ecosystem in order to lessen the consequences of deforestation and other types of pollution.

Better Farming Methods

•    Slash-and-burn farming techniques improved Farming, excessive livestock grazing, and shifting agriculture all have an effect on the environment, especially forests. All of these actions need to be controlled.
•    Jhoom farming is one method for lowering forest pollution. In the northeast of India, the land is abandoned after the crops have been harvested. In this soil, weeds, creepers, and wild plants flourish, restoring its productivity. The area is then cultivated once again after that.

Managing overgrazing

•    The effects of unchecked animal grazing on the forest are negative.
•    The delineation of forest areas intended just for grazing is necessary to prevent any impact on the remaining forest areas.
•    Forage from pastures can be supplemented with stored animal feed.
•    A portion of grazing acres can be used to establish warm- or cool-season species while perennial plants recover.

Engagement of Local Communities

•    There are numerous indigenous communities living in the woodlands.
•    The majority of these tribes' income comes from the trees, which they have a strong natural affinity for.
•    Therefore, it is crucial to engage their assistance in forest protection. 


In addition to channeling the earth and preventing erosion, this forest also creates a more valuable and expressible service that generates income than the nation's defense force. Numerous worms, insects, and tiny critters feed on humans and the soil's tunnels, which also serve as a source of nourishment for plants. As their canopies blanket the entire nation, forests also act as a natural deterrent to aerial strikes.
