Web of Creation (www.webofcreation.org) is a similar site, addressed to persons of all faiths, though perhaps a bit less comprehensive as a resource for concerned Christians. Web of Creation remains a highly useful site nonetheless, with manuals, worship plans, and congregational tools of great use.
Last, the Regeneration Project (begun by the aforementioned Rev. Sally Bingham, www.theregenerationproject.org) offers several resources and action plans, as well as a means of connecting with similarly minded persons of faith in your local area.
Of course, this is a limited survey of available items without any comprehensive claims; no doubt, excellent resources have been missed. Even more certainly, better resources will emerge in the future as more and more concerned and talented people devote their hearts and minds and faiths to restoring and rescuing creation. For the environmentally minded Christian, however, these five books and three websites will provide a firm foundation for prayer, action, and advocacy on behalf of God's green earth.
