No Impact Man

Can one live in this world while making no net impact on the environment? Can we live without creating trash, without electricity, without putting toxins in the water? Of course, us merely being alive has an effect on the environment, but on more of a philosophical level, can we live with our net impact on the world at 0?
I know that in my current situation, that would be very hard to do. Recently however, I have been inspired and persuaded to venture a little closer to that road. There is this blog site by writer Colin Beavan that documents a year long experiment that tries to answer this question whether a human, in a modern society, can live without producing any negative impact toward the environment. The site is called "No Impact Man", and it has recently been influencing me a lot.
His philosophy is simple: live life in such a way that is "eco-effective". To describe this he gives the example of Menominee tribe of Wisconsin who have lived off the land, cutting down mass amounts of trees for sale. Yet, with over one hundred years of cutting down trees in the same area, they have ended up with more trees now than when they first began. How? "They have figured out what the forest can productively offer them instead of considering only what they want to take from it." By cutting down the weaker trees, and giving room for the larger trees to grow, it actually helps the environment; almost like grooming it or something.
Humans however, are not following suit. Beavan argues that largely every other species lives with this eco-effective mindset; they just do it. He writes,

Lions neither starve themselves nor gorge to the point of wiping out the gazelle population. Instead, they promote the health of the gazelle herd by culling its weaker members and preventing herd overgrowth which in turn prevents overgrazing of the savannah. Animal waste does not poison the ground but fertilizes the soil so that it can produce more vegetation for the animals to eat. Bees feed on the pollen of flowers but far from damaging them they provide the crucial service of pollinating them.

Can humans live like this? Is it possible to live without killing the planet along with everything else that calls earth its home? I submit that it is possible, and I think that this No Impact man has some great ideas. Check out his site, I definitely recommend it.
