Is the book disappearing

The book is disappearing because electronic devices are taking over. On average the US uses 30 million trees a year and that is why there very little forest space compared to suburbs in the US. Since 2005 children reading books has decreased by 25% and the children have converted to You tube and other apps. 53% of the world prefer to read ebooks as they are easier to locate compared to a book. Incidental reading is the most common reading because the people reading don't actually know that they are reading. The reason behind that is that children who have a Facebook account will be reading statuses constantly without realising it, even though it is in slang it is still reading. Ebooks and books affect the world in different ways. Ebooks are on electronic devices so they can release radiation but books on the other hand affect animals homes by cutting down trees and forest land. The radiation can be handled and reduced but cutting down trees can only be resolved by reducing the amount of copies of a book are made or finding another way to make paper. That is why the book is disappearing in this day and age.
