Ai Weiwei / Artist & Activist

"Creativity is the power to reject the past, to change the status quo, and to seek new potential. Simply put, aside from using one's imagination – perhaps more importantly – creativity is the power to act."

Via The Art Story: Ai Weiwei is the most famous Chinese artist living today. As an activist, he calls attention to human rights violations on an epic scale; as an artist, he expands the definition of art to include new forms of social engagement. In a country where free speech is not recognized as a right, he is viewed as a threat to "harmonious society."

Herman Daly / Ecological Economist

"There is something fundamentally wrong in treating the Earth as if it were a business in liquidation."

Via CASSE: For decades, Herman Daly has been an inspiration to students of economics and public policy — how often do you see students lining up at the end of the semester to have their professor sign their textbooks? Over his career, Herman has taken a courageous stance, swimming upstream against the currents of conventional economic thought. Not content to bequeath his ideas on economic development solely to the academic realm, he did time at the World Bank to change policies in the real world. He also has written books that are popular with citizens around the world. It’s a rare combination indeed to have keen insight, kindness, razor-sharp analytical skill, wit, amazing capacity for work, humility, and an uncanny way with words all rolled up into one human being. It’s a good thing, too — the planet needs Herman Daly.

Johan Rockstrom / Environmental Scientist

“As the global population increases towards nine billion people, sustainable development should be seen as an economy serving society within Earth's life support system.”

Via the Stockholm Resiliance Centre: Johan Rockström leads the Stockholm Resilience Centre, focusing on a new approach to sustainability: the capacity to use change and crisis to spur renewal and innovative thinking. In 2009, working with an international team of scientists, he identified and quantified a set of nine planetary boundaries within which humanity can continue to develop and thrive for generations to come – while crossing them could generate abrupt or irreversible environmental changes. Since then, the boundaries research has spread among international organizations, governments, NGOs and companies and has been adopted as a new framework to guide the discussion about 'sustainable growth.'

Kerryn Higgs / Environmental Historian

"The notion of ever-expanding economic growth has been promoted so relentlessly that 'growth' is now entrenched as the natural objective of collective human effort. The public has been convinced that growth is the natural solution to virtually all social problems – poverty, debt, unemployment, and even the environmental degradation caused by the determined pursuit of growth. Meanwhile, warnings by scientists that we live on a finite planet that cannot sustain infinite economic expansion are ignored or even scorned."

Via Club of Rome: Dr. Kerryn Higgs is an Australian historian and activist who engages with environment, social justice and social-ecological limits issues. Her work includes numerous articles on environment and politics, as well as her book, Collision Course: Endless Growth on a Finite Planet.

“Because, underneath all of this is the real truth we have been avoiding: climate change isn’t an “issue” to add to the list of things to worry about, next to health care and taxes. It is a civilizational wake-up call. A powerful message—spoken in the language of fires, floods, droughts, and extinctions—telling us that we need an entirely new economic model and a new way of sharing this planet. Telling us that we need to evolve.”

In her own words: Naomi Klein is an award-winning journalist, syndicated columnist and author of the international bestsellers, This Changes Everything: Capitalism vs The Climate (2014), The Shock Doctrine: The Rise of Disaster Capitalism (2007) and No Logo (2000). Since This Changes Everything was published, Klein’s primary focus has been on putting its ideas into action.
