Deforestation, Causes and Effects of Deforestation and Reforestation

The destructionof natural forestsbecause of cuttingtrees,logging,makingspace for cattle grazing, mining,extractionof oil,buildingdamsandpopulationexpansionisknownas deforestation. Deforestationisthe clearingof trees,transformingaforestintoclearedland. Deforestation results from removal of trees without sufficient reforestation and usually results ina significantlossof biodiversity. As perthe reportsof Natural Conservancy,loggingaccountsfor32 millionacresof earth’snatural forestseveryyear.By 2011half of earth’sforestsdisappeared.A majorpart of thislosstookplace in the last 50 years alone.Forestgoodsandmostimportantlythe wood,hasbeenthe essential needof the humancivilizationforovercenturiesandcontinuestobe the mainsource of several activitiesthataman performsinhisdayto day proceedings.

But inreality,more than30 people habitatagivensquare kilometerleadstothe destructionof complete balance. – 3) Deforestation for Grass and Land Development: Grass lands are needed for cattle feeding and developing the cattle growing industry. In order to raise the cattle cheaply, some counties followed the deforestation route at it is and cheap allowing local industry to meet the demand of multinationals for cheaper animal products. 4) Forest as Source of Fire Wood –:
  3. 3. Page 3 of 5 Less privileged nations, because of poverty and poor economic conditions, are forced to use forest as a principle source of fire wood for its people. They tend to deforest for fuel wood production leading to large tracts of forest land becoming barren. To replenish the deforested area it would take not less than 12 to 15 years but such duration greatly imbalances the forest sustainability. Besides, it is a widely recognized fact that fire wood as fuel is the most pollution producing material. Effects of Deforestation: There are several effectsof deforestationonearth’sclimate andnature.  Affect the environment: Deforestation has many negative effects on the environment. The most dramatic impact is a loss of habitat for millions of species. Seventy percent of Earth's land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes.  Atmospheric – : For global warmingdeforestationisthe majorcontributor.Deforestationcausesof carbon dioxide inthe atmosphere.Asthe concentrationof carbondioxide increases,alayerformsin the atmosphere thattraps sunradiation.Thisradiationgetsconvertedtoheatandcausesglobal warming.Inothertermsit isknownas greenhouse effect.(Know whatare the greenhouse gases) Deforestationalsoinfluencestreestorelease carbonstores.Scientistssaythatalmost1.5 billiontonsof carbonisreleasedeachyearbytropical deforestation.  Hydrological – : Water cycle inthe nature getsaffectedbydeforestation.Treespull upgroundwaterwiththe helpof theirrootsand thenrelease the watervaporintothe atmosphere.If treesare reduced, the watervapor contentinthe atmosphere isreducedanditresultsindrierclimate.Italso resultsinsoil erosionwhichmayleadtolandslidesorfloods. Reducing forest cover reduces the capacity of the soil to perspire. 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. It is at approximately two metric tons per square kilometer. Deforestation results in soil erosion because tress can bind the soil together. If trees are removed from steep slopes, it may result in landslides.  Biodiversity – : Deforestation results in the decline in biodiversity and many species of living organisms are becoming extinct. Forests support wildlife habitat and the tropical rainforests contribute to 80%of the biodiversity. The removal of trees has led to the degradation of

REFORESTATION: Possible Solutions: Reductioninemissions –:Several international organizationsalongwithUnitedNationsandWorldBank have beenimplementingvariousprogramstocurb deforestation.ReducingEmissionsfrom DeforestationandForestDegradation(REDD) advicesandencouragesdevelopingcountriestoreduce deforestation.  Farming –: Newfarmingtechnologiesshouldbe inventedsothatthe existingresourcesare notdepleted.
