*You will also learn : that the Earth is undergoing many upheavals that threaten the existence of civilization; that despite the alarmist discourse of scientists, the tipping point reached by the planet can still be reversed; that in order to reverse the trend to its advantage, all of humanity must get involved and find solutions quickly; that these solutions are within reach and have already been undertaken by many individuals.

*In June 2012, a group of 21 scientists published a study that announces, no more and no less, the possible end of humanity. The biology of the Earth is on the verge of undergoing an upheaval at least as radical as that of the last ice age, 11,000 years earlier. The human species is not only running towards its loss, but is itself instigating its imminent extinction, by provoking the extinction of animal and plant species with unprecedented speed. Elizabeth Hadly, biologist, and Anthony Barnosky, paleontologist, coordinated the study published in "Nature". Both stress the urgency facing humanity: in 20 years, it will probably be too late to try to alleviate the situation. Go and meet men and women who are convinced that they have a role to play in this fight to save the planet.
