Monday, February 28, 6:30 – 8:30 pm – The Good, The Bad, and Occasionally the Dead: Humanity’s Relationship with Earth’s Nitrogen

The Arnold Arboretum presents an exciting lecture series in 2011: the new Director’s Lecture Series at the Hunnewell Lecture Hall, 125 The Arborway in Boston. The lectures are free but advance registration is required.

On Monday, February 28, from 6:30 – 8:30 pm, Alan Townsend of University of Colorado, Boulder, will discuss the occasionally odd, often dramatic history of humanity’s relationship with phosphorus and nitrogen. How do we live the lives we want while maintaining healthy ecosystems that can support future generations? These challenges will define the coming century, and one of them lies at the heart of the most fundamental of human needs: the need to eat, the good these chemical elements do and the harm they cause, and ultimately, the reasons to have hope for a better future.  NASA image below shows nitrogen dioxide concentration over China.
