The increasing use of financial values for ecological things (trees, bees, etc.) is deeply problematic.
In Canada for instance PeterBorough’s Green Up and Urban Forest Stewardship Programme (as reported in the Peterborough Examiner) has been literally tying price tags to trees to highlight their importance to members of the public. The value attributed is over 50 years and it does identify the different aspects of the value of trees,
“The tags list oxygen generation ($31,250), air pollution control ($62,000), water recycling ($37,500) and soil erosion control ($31,250) as a tree’s top contributions to a community.â€
Whilst this at least acknowledges some of the complexity, English Nature reported that “Bees are worth £200 millionâ€. This was originally reported on the BBC at about the same time that Lehman Brothers collapsed with a reported figure in the region of $613 billion.
Dave Pritchard recently commented on the ecoartnetwork dialogue (9 April 2011),
“For a time, in the 1970s-80s, there was some of the kind of “reconsideration†you describe, with the “deep ecology†of Naess, Bateson, Berry et al. But if you analyse the evolution of the actual policy and advocacy discourse at 10-yearly intervals, for example from the 1972 Stockholm Conference to the 1982 World Conservation Strategy to the 1992 Rio Conference to the 2002 Johannesburg Summit (and then maybe in advance of the Rio+20 summit in 2012 look at the Aichi targets adopted last year), it has swung completely away from any ethics of “existence value†for the non-human component, to a forced justification (in adversarial arenas) in terms of “sustainable developmentâ€, “wise useâ€, “evidence-based conservationâ€, “ecosystem services†and (largely monetary) valuation of those services. The environmental movement (of which I am a part) congratulates itself on having found better ways of expressing the critical nature of ecosystems within broader mainstream audiences and processes, in this way. But this has all been done by becoming MORE anthropocentric and utilitarian; not less.â€
Could the same narrative be written about both education and the arts (a.k.a the creative industries)? 
ecoartscotland is a resource focused on art and ecology for artists, curators, critics, commissioners as well as scientists and policy makers. It includes ecoartscotland papers, a mix of discussions of works by artists and critical theoretical texts, and serves as a curatorial platform.
It has been established by Chris Fremantle, producer and research associate with On The Edge Research, Gray’s School of Art, The Robert Gordon University. Fremantle is a member of a number of international networks of artists, curators and others focused on art and ecology.
We invite video artists worldwide to participate with works that explore Global Warming, focusing on forests in honor of the United Nations International Year of Forests 2011. Artists are encouraged to tell us their stories about deforestation or tree planting and its positive effects; they may also opt to approach the topic from symbolic, psychological or socio-political significances of forests. Our aim is to present a convincing survey of the current artistic exploration of this topic worldwide with 20 established and emerging artists, edited into a visually and conceptually coherent compilation by
