There are a few blogs on environmental issues that I thought I'd mention –
Rev. Neddy Astudillo has a blog in Spanish called Eco-Justicia. Rev. Astudillo is the pastor at Parroquia San José, a PC(USA)-ELCA – Latino Ministry in Beloit, Wisconsin. She has led classes on eco-justice at seminaries in Guatemala, Peru, and Bolivia.
Earth Ministry's blog To Inspire and Mobilize touches on issues of faith and the environment.
The Congregational Resource Guide has a new blog on green issues.
