This is the day that we commemorate one of the most diverse and most important natural resource that we have: Indeed, it is alarming at how fast the forest cover of the earth is diminishing. It is alarming because the forest is possibly the single most important resource for us humans, and alarming also because it is a sign of our callousness and negligence that we are allowing these regions to disappear forever for some momentary gains.
In honor of this seasonal focus on trees and forests, here's a list of 21 reasons why they're important: They help us breathe. Forests pump out oxygen we need to live and absorb the carbon dioxide we exhale or emit.
A single mature, leafy tree is estimated to produce a day's supply of oxygen for anywhere from two to 10 people. Phytoplankton are more prolific, providing half of Earth's oxygen, but forests are still a key source of quality air. They're more than just trees.
Nearly half of all known species live in forests, including 80 percent of biodiversity on land. That variety is especially rich in tropical rain forests, from rare parrots to endangered apes, but forests teem with life around the planet: Bugs and worms work nutrients into soil, bees and birds spread pollen and seeds, and keystone species like wolves and big cats keep hungry herbivores in check.
People live there, too. Some million people live in forests worldwide, including an estimated 60 million indigenous people whose survival depends almost entirely on native woods.
Many millions more live along or near forest fringes, but even just a scattering of urban trees can raise property values and lower crime. The canopy towers over a coastal-plain forest in Italy's Nazionale del Circeo.
They keep us cool.
By growing a canopy to hog sunlight, trees also create vital oases of shade on the ground. Urban trees help buildings stay cool, reducing the need for electric fans or air conditioners, while large forests can tackle daunting tasks like curbing a city's "heat island" effect or regulating regional temperatures.
They keep Earth cool. Trees also have another way to beat the heat: Plants always need some CO2 for photosynthesis, but Earth's air is now so thick with extra emissions that forests fight global warming just by breathing.
CO2 is stored in wood, leaves and soil, often for centuries. They make it rain. Large forests can influence regional weather patterns and even create their own microclimates. The Amazon, for example, generates atmospheric conditions that not only promote regular rainfall there and in nearby farmland, but potentially as far away as the Great Plains of North America.
Tree roots are key allies in heavy rain, especially for low-lying areas like river plains. They help the ground absorb more of a flash flood, reducing soil loss and property damage by slowing the flow.

Modern stormwater increasingly carries toxic chemicals, from gasoline and lawn fertilizer to pesticides and pig manure, that accumulate through watersheds and eventually create low-oxygen " dead zones.
Forests are like giant sponges, catching runoff rather than letting it roll across the surface, but they can't absorb all of it. Water that gets past their roots trickles down into aquifers, replenishing groundwater supplies that are important for drinking, sanitation and irrigation around the world.
Farming near a forest has lots of benefits, like bats and songbirds that eat insects or owls and foxes that eat rats.Importance of Forests Forests and biodiversity are key to all life forms. The richer the diversity of life, the greater the opportunity for medical discoveries, economic development and adaptive responses to such new challenges as climate change.
Below are some more importance of forests: Watershed Forests serve as a watershed. Importance of forest – Essay, Article, Speech, Paragraph Introduction (Essay on Importance of Forest) Forest is a large area of land covered by trees and woody vegetation/5().

This is the day that we commemorate one of the most diverse and most important natural resource that we have: the vast woodlands that once covered the earth, and are now fast disappearing.
Forests also support biodiversity by offering enabling environments where different plants and animals can easily thrive. Forests also support the life of some of the world’s endangered species.
Purifies the Air; Forests play an important role in the purification of the atmospheric air. Similarly, the gas and air pollution diffuses to all over the air and get less severe.
Presence of forest nearby helps absorb these pollutants like carbon dioxide from the air by the trees. Hence, forests have environmental benefits too. 6. Economic importance: Forest have significant economic benefits.
Few countries economy depends mostly on forest products.
