Advertisement and marketing can ultimately change the world for the better. We now have the ability of world wide communication, which leads to accountability on our end for creating campaigns that could benefit the world.
For instance our ecosystem is vast but yet polluted. Advertisement campaigns can enforce people to care or at least know & be involved with what is happening to ecosystems through communication channels.
We have the power to put advertisements in front of a mainstream of audiences who can be the catalyst to making a movement.
For advertisements to change the world for the better we need to focus on how we can change the world for the better and then proceed.
