What does "this" in the following paragraph refer to?
Technology is shaping tomorrow’s society by conquering today’s
teenagers. Nowadays, teens seem incapable of having a quality face-to-face
conversation that lasts more than 2 minutes. Experts attribute this
to the lack of meaningful interaction and social habits, which are a direct
consequence of modern technology. Basically, people have the need to be
connected to each other 24 hours a day, 7 days a week but never in person.
Loads of thanks in advance.
