what is deforestation?
Deforestation, clearance, clearcutting or clearing is the removal of a forest or stand of trees from land which is then converted to a non-forest use.
Deforestation can involve conversion of forest land to farms, ranches, or urban use.
The most concentrated deforestation occurs in tropical rainforests.
Deforestation is the permanent destruction of forests and woodlands.
Cutting down forests not only threatens the extinction of a diverse range of plants and animals, but also causes climate disruption:deforestation is responsible for around 20% of global CO2 emissions, making it a major contributor to climate change.
There are 3.04 trillion trees on Earth.
The study found that there are around 3.04 trillion trees on Earth, or around 422 for each person on the planet.
The number is a huge increase on the previous global estimate, which was just over 400 billion trees worldwide.
