The century old vision of the common good as expressed in urban parkland is at least partially realized in Boston’s Emerald Necklace. Thinking about the parks that were, and were not, built over the last decades is a great way to consider our climate-constrained future. What lessons should we learn about the interplay of green spaces in dense urban areas? We talk with an author and champion for urban hiking.

The reading list:

• Pictures and commentary on the finished portion of the Emerald Necklace
• Pictures and commentary from hiking the unfinished portion of the Necklace
• Follow Miles at @MilesPerHoward
• Miles Howard home page
• Howard in the Globe on urban hiking
• 2015 Globe article on Olympic Plans for Columbia Road
• An overview of Olmsted and links to maps from the Emerald Necklace Conservancy
• Olmsted and Central Park
• Buttonwood Park
• Olmsted Parks that weren't- an article on the history of the Necklace
• Saving trees on Melnea Cass Boulevard

Because we recognize the necessity of personal accountability for our actions, because we accept responsibility for a building a durable future and because we believe it is our patriotic duty as citizens to speak out, we must insist the United States transform it’s energy sector, over the next decade, under a just and equitable plan, that uses regulations, investments and a price on carbon to safeguard our collective future.

Thanks for listening.
