Advertising is supposed to make people buy certain products. However, that is not only what advertising is about. David Ogilvy, probably the biggest name in advertising, once said,

Advertising justifies its existence when used in the public interest—it is much too powerful a tool to use solely for commercial purposes.

However, today, we hardly see advertising being used for any meaningful purpose. Most of the ads we see on television and in print tend to exploit that corner inside us which craves for products that we know deep down are of no use and are going to do us no good. Luckily for us, there are some agencies around the world that use advertisements to try and raise awareness about social issues we all should know about. Issues that are harming the environment, creating conflicts in the world, and harming our own personal health.

Here's a look at 28 of these powerful and shocking advertisements.
