NEW YORK – Great social change occurs in several ways. A technological breakthrough – the steam engine, computers, the Internet – may play a leading role. Visionaries, such as Mahatma Gandhi, Martin Luther King Jr., and Nelson Mandela, may inspire a demand for justice. Political leaders may lead a broad reform movement, as with Franklin Roosevelt and the New Deal.

Our own generation urgently needs to spur another era of great social change. This time, we must act to save the planet from a human-induced environmental catastrophe.

Each of us senses this challenge almost daily. Heat waves, droughts, floods, forest fires, retreating glaciers, polluted rivers, and extreme storms buffet the planet at a dramatically rising rate, owing to human activities. Our $70-trillion-per-year global economy is putting unprecedented pressures on the natural environment. We will need new technologies, behaviors, and ethics, supported by solid evidence, to reconcile further economic development with environmental sustainability.

United Nations Secretary-General Ban Ki-moon is taking on this unprecedented challenge from his unique position at the crossroads of global politics and society. At the political level, the UN is the meeting place for 193 member states to negotiate and create international law, as in the important treaty on climate change adopted at the Rio Earth Summit in 1992. At the level of global society, the UN represents the world’s citizenry, we the peoples, as it says in the UN Charter. At the societal level, the UN is about the rights and responsibilities of all of us, including future generations.

In the past two decades, governments have come up short on solutions to environmental threats. Politicians have failed to implement properly the treaties adopted at the 1992 Earth Summit. Ban knows that strong government action remains vital, but he also recognizes that civil society must also play a larger role, especially because too many governments and politicians are beholden to vested interests, and too few politicians think in time horizons that extend past the next election.

To empower global society to act, Ban has launched a bold new global initiative, for which I am grateful to volunteer. The UN is a powerful effort to mobilize global knowledge to save the planet. The idea is to use global networks of knowledge and action to identify and demonstrate new, cutting-edge approaches to sustainable development around the world. The network will work alongside and support governments, UN agencies, civil-society organizations, and the private sector.

Humanity needs to learn new ways to produce and use low-carbon energy, grow food sustainably, build livable cities, and manage the global commons of oceans, biodiversity, and the atmosphere. But time is running very short.
