  • The Double-Edged Sword of Geoengineering

    The Double-Edged Sword of Geoengineering

    Shooting sulfur particles into the stratosphere to reflect the sun? Dumping iron into the ocean to boost the absorption of carbon dioxide? Could these far-fetched and dangerous-sounding schemes—geoengineering—help avert potentially catastrophic effects of climate change, or would they exacerbate conditions on our ever warming planet?

  • Why Soil Matters

    Why Soil Matters

    Soil is the source of all life. Yet “we know more about soils of Mars than about soils of Africa,” says Pedro Sanchez, director of the Earth Institute’s Tropical Agriculture and the Rural Environment Program. To remedy this situation, the Earth Institute is taking part in an ambitious undertaking to map the world’s soils.

  • Facing the Food and Water Challenges of the Future

    Facing the Food and Water Challenges of the Future

    The global population, now 7 billion, is expected to reach 9 billion by 2050 and will require 70 percent more food than we are producing today, and much more water for agriculture, drinking and industry. Will we have enough water to meet the demand?

  • Indian Point: Safe, Secure and Vital or an Unacceptable Risk?

    Indian Point: Safe, Secure and Vital or an Unacceptable Risk?

    The owners of Indian Point nuclear power plant want to re-license the facility for 20 years. Opponents say the plant is unsafe and we can do without its electricity. Supporters say it’s safe, and we need the power.

  • Data’s Power to Spur Environmental Progress

    Data’s Power to Spur Environmental Progress

    In January, 132 countries received their environmental report cards. The Environmental Performance Index has goaded leaders into action by letting them see their countries’ strengths and weaknesses compared to other countries.

    What Happens to All That Plastic?

    Americans discard about 33.6 million tons of plastic each year, but only 9.5 percent of it is recycled and 15 percent is combusted in waste-to-energy facilities. What happens to the rest of it?

    Building NYC’s Resilience to Climate Change With Green Infrastructure

    Climate change will impact New York City through more frequent heavy precipitation, sea level rise and rising temperatures. To strengthen its resilience, the city is planting trees and mini-parks, restoring wetlands and installing more permeable surfaces.

  • Restoring Damaged Ecosystems – The Challenge of Haiti

    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

    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.”
