In my opinion advertisements aren't really essential in our lives and there are plenty of arguments to prove it.. If we want to know more about a product we can easily go to a shop and read its characteristics. Advertisements often make people buy staff they don't really need. Nowadays ads are more than often just lies told in a very clever way, which leads to manipulating consumers. Advertisements that are shown in television not only take viewers' time, but also make people greedy when they hear about more and more new products. Summarizing, ads aren't very important in our lives, because they are often lies, make us buy useless staff and just waste our time.
