Saving trees can one advantage of involving into more internet stuffs for reading rather than go with the traditional books were saving trees and lot of man power expenses,but it has the disadvantage of making people more lazy and getting addicted to the internet by just looking at the internet for everything.So this has positive as well as the negative we need to use the advanced technology in more beneficial way.
What is the "it" you're talking about here? Electronic books? How can electronic books make people more lazy? Now people don't need to go to the store to buy books, but they'll probably spend about the same amount of time reading as they did before. If you're talking about the internet in general, how is looking things up online a symptom of laziness? What would be the "non-lazy" option? To go to the library and look things up? I think, in this sense, technology is just saving our time and giving us instant access to the information of the whole world.
