what are books? how many trees are cut for a paper
Answers
books are a bundle of papers helps to know information around us.As for how many trees are cut down each year, the 2005 report concludes that primary forest area (as opposed to plantations)was reduced globally by 60,000 square kilometers per year (about the size of Ireland). Note that this data is incomplete due to a lack of available data from many countries who do not monitor such change. As to the "number of trees" this represents, it's impossible to get an accurate count. Tree density in primary forests varies from 50,000-100,000 trees per square km, so the math would put this number at 3 billion to 6 billion trees per year.
As for what purpose this logging is for, a 2007 report provides statistics on global production and consumption of woodfuel (charcoal and other energy uses) roundwood (paper and other non-lumber products) and sawnwood (lumber). It estimates global production at 1.7 billion (46 percent) , 1.6 billion (43 percent) and 421 million (11 percent) cubic meters respectively with comparable volumes consumed globally.
