When will we reach the breaking point? Our minds have become a virtual dumping ground of pollutants - manipulative ads, distorted news, untold violence, spin and hype. We can cope with the media onslaught to a degree. But all signs suggest that the cumulative effects of this toxic culture - on our stress levels, our moods, our relationships, our world views, even our mental health - could become one the most pressing issues of our generation.
This online activist network - 30,000-strong - is working to rethink our broken media system. We invite you to join by signing the Media Carta manifesto.
Media activism is still in its infancy and is currently fragmented into dozens of different agendas.
