Does the internet bring more harm than good? (This is an actual question from my class)
Amiraneli [1.4K]
This is a opinion question rather than a factual question. However, many researchers have found that though the internet does provide many harmful things (it has brought a whole new level to prostitution as well as the drug cartel and other illegal substance/objects that are sold), the good will forever outweigh the bad. The internet has caused us to be able to disperse and collect information from all over the world and has helped us create many scientific as well as technological advancements. Though there will terminally be things people will use the internet for that is "bad", the good outweighs the bad on what is has and will do for us.
