The Cutting of Trees









A health planet needs a health forest. The prosperous forests regulate the water cycle and they stabilize the ground. The forests also helps to moderate the climate by absorbing and storing the carbon dioxide. Furthermore for this services like ecosystem, the forests provide habitats for the diverse flora and fauna.





If I could stop the cutting of trees I know that I would help a lot the world because the forests help the air.




Deforestation




Deforestation is the clearance of naturally occurring forests by logging and burning.


Deforestation occurs for many reasons: trees or derived charcoal are used as, or sold, for fuel or as a commodity, while cleared land is used as pasture for livestock, plantations of commodities, and settlements. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland.


Deforestation is a contributor to global warming, and is often cited as one of the major causes of the enhanced greenhouse effect. Tropical deforestation is responsible for approximately 20% of world greenhouse gas emissions. According to the Intergovernmental Panel on Climate Change deforestation, mainly in tropical areas, could account for up to one-third of total anthropogenic carbon dioxide emissions. But recent calculations suggest that carbon dioxide emissions from deforestation and forest degradation (excluding peatland emissions) contribute about 12% of total anthropogenic carbon dioxide emissions with a range from 6 to 17%. Trees and other plants remove carbon (in the form of carbon dioxide) from the atmosphere during the process of photosynthesis and release oxygen back into the atmosphere during normal respiration. Only when actively growing can a tree or forest remove carbon over an annual or longer timeframe. Both the decay and burning of wood releases much of this stored carbon back to the atmosphere. In order for forests to take up carbon, the wood must be harvested and turned into long-lived products and trees must be re-planted.



This is a little introduction about the cutting of trees and the deforestation.



If I would stop this things I think I would re-plant the trees or other kind of plants, because the world needs the process of photosynthesis, and if the people of the world don't do anything for it, the global warming its going to grow, and it will be worse than now.



Help the world.
