What percentage of the world is forest?

How many trees were there 1000 years ago?
We had rudimentary estimates based on satellite imaging technology, but estimates based on satellite imaging varied. The lazy estimate at the time was that there were approximately 400 billion trees on the planet–not based on particularly good or well-documented science.
How long until trees are cut down?
There are three trillion trees in the world. The timber industry currently cuts down 15 billion a year, so at current rates it would take at least 200 years to fell them all – probably much longer because a lot of virgin forest is hard to reach.
Are forests growing or shrinking?
Around the world, forests are shrinking due to deforestation, urban development and climate change, but in Europe that trend has been reversed. Large areas of the continent have seen a forest boom that means today more than two-fifths of Europe is tree-covered.

Will we ever run out of trees?

How long until all forests are gone?
In just 40 years, possibly 1bn hectares, the equivalent of Europe, has gone. Half the world’s rainforests have been razed in a century, and the latest satellite analysis shows that in the last 15 years new hotspots have emerged from Cambodia to Liberia. At current rates, they will vanish altogether in 100 years.
Do loggers replant trees?
A. Yes. Forest products companies are in the business of growing and harvesting trees, so reforestation is important to them. … And logging companies pay a special fee to fund for replanting and reforestation when they buy the right to harvest a section of timber on state or national forests.
