 | Colin Beavan "A crisis, they say, is a terrible thing to waste. And there is more than one crisis. First, is the crisis in our climate--we must figure out how to get CO2 down to 350 ppm in a matter of years. Second, is the crisis in our way of life. In the developed world, people suffer from anxiety and depression in epidemic proportions. In the developing world, over one billion people have no access to clean drinking water. We must do better. We have a chance to find an improved way of life, both for ourselves and for our planet. Let's take it." Colin Beavan, aka "No Impact Man," is an author, and most recently, a film star of the brand-new movie "No Impact Man."

 | Homero Aridjis "We are already experiencing global climate change. This campaign will make 350 ppm a goal for the whole world. Every nation on the planet must be included in the upcoming global treaty, yet it will be the developed countries' responsibility to make the quickest and most drastic emissions reductions. No country can remain outside of this agreement that is our last opportunity to save the planet from this looming catastrophe." As a child, Aridjis would often walk up a hillside near his home to watch the migrating monarch butterflies. As he grew older logging thinned the forest. This and other events in his life caused him to co-found the Grupo de los Cien, the Group of 100, an association of one hundred artists and intellectuals that became heavily involved in trying to draw attention to and solve environmental problems in Mexico. Aridjis has published 38 books of poetry and prose, many of them translated into a dozen languages.

 | José María Figueres "During the last ten thousand years we have enjoyed a period of unprecedented climate stability. Today, as a result of man-made activities, climate is changing. The consequences of these changes represent the greatest challenge humanity has ever faced. Going forward, we will do three things with respect to Climate Change: mitigate, adapt, and suffer. Our option consists in choosing the mix. If we exercise leadership and act now, we will mitigate aggressively (reduce carbon emissions), adapt less, and suffer little. If we go on with a ‘business as usual attitude’, we will mitigate little, need to adapt more, and suffer profoundly. Let’s rise to the challenge with courage and determination, and reduce our global carbon footprint to 350 ppm! We can do this by joining efforts between the North and the South, and business and governments!" José María Figueres is former President of the Republic of Costa Rica (1994-1998) and currently CEO of Concordia21 in Spain.
