Is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use.
Examples of deforestation: conversion of forestland to farms ranches or urban use.
Definition of deforastation

Facts
According to the United Nations Food and Agriculture Organization (FAO), an
estimated 18 million acres of forest are lost each year.

Solutions1 •Curb the felling of trees, by employing a series of rules and laws to govern
2 •Clear cutting of forests must be banned.
3 •Cutting must be replaced by planting young trees to replace the older ones that were cut.

Atmospheric
increasing emissions of greenhouse gases worldwide
high temperature generates cloud formation due to increased levels of rainfall in soil
Hydrological
reducing the water content of soil and atmospheric humidity
Deforestation : reduces soil cohesion facilitates erosion Increases flooding

Soil• Tree litter increases the rate of soil erosion • Lack of roots generate water leakage and floods• Roots hold the soil together; without them, landslides
happen

Biodiversity
deforestation causes the disappearance of many species.
destruction or removal of forests lead to reduced biodiversity.
forests support biodiversity, providing habitat for wildlife.

ControlReducing emissions
• Relies on sound scientific basis• A cost effective method of greenhouse gas emissions
mitigation• Sustainable economic benefits• Ethical distribution of commercial rewards• Quantifiable biodiversity benefits

Forest management it takes centuries to try to stop or to slow deforestation environmental problems can cause societies to collapse

Forest plantations
Plantation for timber production : cultivation
long-term management of trees on marginal agricultural land.
Plantations are generally : even-aged planted
managed in rows consist of a single species

Conclusion: Deforestation destabilizes the natural circuit. Reasons can be human or natural. It is up to us to mobilize by planting and caring for trees.
