I started composting in 1970 by taking my food scraps out behind where I lived and burying them in a hole next to the railroad tracks - and green things started to grow there!

My favorite form of transportation is walking. I live in a neighborhood where you can walk to restaurants, banks, and shops.

This is a deeply spiritual issue...Do we want to spend more time trying to care for our fellow man or do we want to just pursue more virtual reality? That's the issue before us.. and it's being played out in the world of the environment.

The film 'Tapped' illustrates quite clearly how we've been getting 'soaked' for years by the bottled water industry.

What we often fail to recognize is how efficient a vegan diet is. Less land, less water, more food for our spiraling population.

I'm a strong proponent of green tech for anyone who can afford it, having spent the last 40 years working toward achieving a smaller and smaller eco-impact for myself.

The environmental crisis is all a result of rushing.
