    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?

    The good ‘ol forest growth curve [update]

    While the New Jersey bill failed, it is going to be discussed in New Jersey’s Senate Environment Committee on Monday, January 30, 2012. The discussion is not yet over regarding New Jersey’s public forests. The discussion about ecosystem productivity over time also continues in the forum of the Native Tree Society. Specifically, this post was picked…

    Seeking the Signal in the Noise of Environmental Performance Metrics

    The 2012 Environmental Performance Index is a powerful tool for diagnosing trends not just across countries but over time, too. Consider what we can learn about overfishing, for example.

  • Ecological Succession: Forest Fires to the Ocean Floor

    Ecological Succession: Forest Fires to the Ocean Floor

    A new study reveals that new microbes supplant the active hydrothermal vent’s microbes after the site ceases to produce thermal energy. Though more research is necessary to fully understand the regeneration process in the dormant hydrothermal vents, the study provides an additional platform for ecologists to explore how ecosystems recover from natural unbalances and how…

    Eco-Markets: Business, Regulation, and Sustainability

    Interested in learning more about environmental markets and the nexus between business, regulation, and sustainability? How does an organization trade carbon credits?

  • Disease Ecology and Conservation Medicine

    Disease Ecology and Conservation Medicine

    Disease Ecology provides an overview of the principles of conservation medicine and disease ecology, with an emphasis on the effect of disease on human, wildlife and domestic animal and ecosystem health. It examines the impact of disease on biodiversity and rates of extinction, as well as the rise of emergent diseases as a result of…

    One Billion Gallons a Day, Naturally

    If not for the amazing feats of planning and engineering that provide access to clean water, New York City would never have become the essential node in the many meshworks of the world that it is today.

  • African Forests, Threatened, but Resilient

    African Forests, Threatened, but Resilient

    Forests and climate change are fundamentally interrelated.  Forests play a role in mitigating climate change by trapping and storing carbon in their trees.  Currently, the world’s forests and forest soils store more than one trillion tons of carbon – twice the amount in the atmosphere. The African continent is home to 30% of the world’s…
