Wish you could ask Laurie David, producer of Al Gore’s “An Inconvenient Truth” your questions about the environment? How about chatting with Newt Gingrich about bipartisan environmentalism? For those unacquainted with Slate.com’s Earth Chats, it’s a great online discussion series featuring leading environmental thinkers, leaders and advocates who answer readers’ questions about environmental issues, and what we can do to improve our earthly habitat. This week being Earth Week, Slate chatted with a slew of heavy-hitting advocates. We’ve provided this week’s schedule below, with accompanying links to chat transcripts:

Monday
Read the transcript of our chat with conservative conservationist Newt Gingrich. After serving 20 years as a Republican congressman, Gingrich has devoted himself to a bipartisan “mainstream environmentalism,” which he outlines in his 2007 book A Contract With the Earth.

Read the transcript of our chat with author and advocate Bill McKibben, who has been writing books on environmentalism for almost 20 years. He’s written a handbook on how to stop global warming and a treatise on the importance of having smaller families. In Deep Economy, just out in paperback, McKibben lays out an economic policy that focuses on local communities, as opposed to unending “growth.”

Tuesday
Read the transcript of our chat with Academy Award-nominated actor and environmental activist Edward Norton. Norton is the host of National Geographic’s Strange Days on Planet Earth, which covers topics like climate change, overfishing, water pollution, and the quest for clean energy. He also helped start a program to provide low-income families in Los Angeles with solar-powered homes, and he has worked on promoting the development of green spaces in urban areas.

Friday
1:30 p.m. ET: Global-warming activist Laurie David. David was a producer of Al Gore’s An Inconvenient Truth and is the creator of environmentally themed programming for TBS and HBO. She also founded the Stop Global Warming Virtual March with Sen. John McCain and Robert F. Kennedy Jr., and blogs on environmental issues at the Huffington Post.
