Inspired by John Muir's A Thousand-Mile Walk to the Gulf, John Davis walks, bikes, and kayaks on a 'voyage of recovery' from the Florida Keys to southeastern Canada. He bears witness not only to wilderness that still sustains bears, panthers, and bobcats but also to the possibilities for connecting further wildways in the eastern United States. His inspiring journey reminds us all that we must rediscover the wildness we still have before we lose it forever.

Civil disobedience can help to focus attention on a particular injustice. It was used historically to highlight wrongs in society - turning ancient redwood forests into paper towels or preventing people from sitting down at lunch counters because of the color of their skin. On climate change, we have not seen strong leadership coming from Washington, DC.In particular the president has an enormous opportunity to follow up on his inaugural speech with a concerted course of action to aggressively take on a clean energy transition.

Natural gas is not a bridge - it's a gangplank.

Rome wasn't built in a day, and we won't replace fossil fuels with clean energy based on the events of a single week, either. But the important thing to remember is that, once they happen, clean energy victories are irreversible. No one will tear down wind farms because they are nostalgic for fracking in our watersheds. And nobody will pull down their solar panels because they miss having mercury in their tuna or asthma inhalers for their kids. Because once we leave fossil fuels behind, we are never going back.

Paradigm shifts aren't always obvious when you're in the middle of one. Danny Kennedy makes a compelling case for why solar power is the crucial energy technology of the 21st century.

We know how to get all of the energy we need without using dirty or dangerous fuel sources. It is no longer a question of whether we can - but of whether we will
