In my opinion, Junk food should be banned in school because it will effect on the students negatively. Students well be lazy because of the salt and chemicals in the junk food. also junk food will harm their heath and their mind will be lost and they will get low marks.
I don't see any problem with having voids , in fact it just gives us an option to replace the bookshelves with anything we want or we like . Nowadays companies from all around the world are depending on modern technology to do their work so it is expected to see less books , less bookshelves and more computers or laptops .
