Earth Day should be everyday. If only the world would be a little more veggie, a bit more green, and read more digitally, we would be a much more sustainable and environmentally sound planet. And, we would save and sustain trees.

On a serious note, Zinio helps save more than 104,000 trees every month. And it contributes more wealth in terms of information and entertainment on our newsstand. We recognize we have a lot of magazines (over 5,500), but sometimes we look twice and realize we’ve aggregated more quality content in one arena or another than just about any source you can find. There’s a lot of great writing and photography from a broad spectrum of journals from around the world. Zinio has something for everyone, whether it’s the politics of global warming or just getting out and enjoying the natural world.

We’re celebrating in two ways this week. First, with a sale of over 100 titles at up to an additional 50 percent off And, we’ve created a content collection of some of our favorite magazines that support sustainable articles you can read for free here:

Sierra: It’s a lot more than the official magazine of the Sierra Club. Sierra is arguably the only magazine that can teach you how to fly. Its most recent issue features a series of stories on wind energy, including a piece on gear you can buy to harness the wind to literally fly. Get your wingsuit. What I love about Sierra digital are the great photos and the balance between caring for the environment and caring for the economy.

Green Ideas: The US market should have one of these. It’s a New Zealand-based magazine. But the practical and tactical content in Green Ideas are truly global. For me that, what digital publishing is all about: No borders. It’s A consumers’ guide to living more sustainably – loaded with ideas and practical advice for people who want to know more about the environment and minimize their impact on it.

Whole Living: Think Martha Stewart goes green. Whole Living puts a bit of a glitzy spin on eating with a healthy approach, entertaining with a green approach and looking into the “healthy circle” of upscale communities that are living closer to the earth.

Green Source: Another great case for digital publishing. I discovered this magazine while I was looking for some design advice for a home improvement project. I found this, which is a brilliant looking journal for professionals. Green Source covers sustainable design, green building case studies for architects, engineers, designers, contractors and owners. It might sound boring on the surface. But it feels like you’re being invited into an exclusive club.

Outside: This pick might be a little popular but you simply can’t ignore the excellence, writing and sheer visual power of Outside. The only thing its readers are more passionate about than working out and extreme sports is the environment.
