Restoring Damaged Ecosystems – The Challenge of Haiti

In 2010, almost two-thirds of the world’s ecosystems were deemed degraded due to human impacts and mismanagement, but fortunately ecosystems can be restored. The Earth Institute’s work in Haiti illustrates just how complicated ecosystem restoration can be.
Rethinking Our Food System to Combat Obesity

The Earth Institute’s Urban Design Lab and MIT Collaborative Initiatives joined to investigate the issue of obesity through the prism of design. Their conclusion: “No single effort to curb childhood obesity will be sustainable or effective on a broad scale if the larger food system is not addressed.”
How You Can Help Earth Cope with 7 Billion

Earth’s population has more than doubled in the last 50 years to 7 billion. The numbers represent big challenges—feeding and providing for additional people on a planet already stressed by environmental damage and climate change. What can ordinary individuals do?
Vertical Farms: From Vision to Reality

Dr. Dickson Despommier believes vertical farming—the growing of crops indoors in multi-story urban buildings—can help feed the growing global population and undo the environmental damage caused by conventional agriculture.
Removing Dams and Restoring Rivers

On Sept. 17, 2011, the removal of two large hydroelectric dams on the Elwha River in Washington State, which have blocked migrating salmon from reaching their spawning grounds for almost 100 years, will begin. While this is the largest dam removal project in U.S. history, it is just one of several major dam removals planned…
Is Biomass Really Renewable?

Ninety percent of all existing biomass power plants use wood residue and there are currently 115 power plants in development that will burn biomass to generate electricity. But just how renewable is biomass energy?
Mountaintop Removal: Laying Waste to Streams and Forests

Mountaintop removal mining, an environmentally devastating form of coal mining that involves blowing off the tops of mountains, has already leveled over 500 mountains and buried 1,200 miles of streams in the Appalachians.
Have We Crossed the 9 Planetary Boundaries?

“The world needs to awaken itself to the looming catastrophe of global warming,” said Jeffrey Sachs, Director of the Earth Institute, at a recent meeting in Muscat. “We must provide a safe operating space where vested interest and lobby-driven policies will not see the world marching into disaster.”
Maintaining the Superiority of NYC’s Drinking Water

New York City is world-renowned for its clean and delicious drinking water. The NYC watershed delivers roughly 1.2 billion gallons of unfiltered water each day to 9 million New Yorkers. But in 2013, the Croton Water Filtration Plant, currently under construction in the Bronx, will begin filtering 1.2 million cubic meters or 10% of New…
