In these days, what we need is for people to take action (from voting and raising their voices in the media, to working on how to live in a sustainable way as a civilization), and promote a positive message that others will follow. Depression-inducing articles like this one risks to prevent people from believing in a decent future, and thus persuade them to stop caring and acting for a better world.
