Deforestation probably originated with the use of fire, and estimates are that 40–50% of the Earth’s original forest area has been lost. Some of that loss happened before settled agriculture began, approximately 10,000 years ago, but only in recent decades is there reliable information on rates of deforestation.
How did deforestation started?
Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. Rarely is there a single direct cause for deforestation.
Where did deforestation occur?
Today, most deforestation is happening in the tropics. Areas that were inaccessible in the past are now within reach as people build new roads through the dense forests.
When did deforestation start in the US?
About half of eastern North America lay deforested in the 1870s, almost all of it having been deforested at least once since European colonization in the early 1600s. Since the 1870s the region’s forest cover has increased, though most of the trees are relatively young.

Global deforestation reached its peak in the 1980s. We lost 150 million hectares – an area half the size of India – during that decade. Clearing of the Brazilian Amazon for pasture and croplands was a major driver of this loss.

That’s 6 billion hectares. Today, only 4 billion hectares are left. The world has lost one-third of its forest – an area twice the size of the United States. Only 10% of this was lost in the first half of this period, until 5,000 years ago.
