Why books are disappearing

Before researching:

I though that books where disappearing and that people were buying more technology, and that kids were getting a bit stupider more and more (as in not academically I mean perceptionaly and their knowledge about things) and I thought that technology is good and bad on the society 

After researching: 

I found out what books are a bit worse than technology because to make paper you need to chop down trees and that ruins the environment, even though technology has a bit of a bad impact on society, it also has a good impact, for example charities online, and orgonisations to stop making fun of gay people
