I think Gene and Cheryl put it quite well. It all comes down to the simple fact that all systems and life/energy processes here on Earth are interconnected. A change in one affects others - sometimes in ways that are not immediately obvious. And because the interrelationships are so complicated, I believe in the precautionary principle. The overall system (planet) will adapt to any change and continue on, but because individual species (including homo sapiens) may only be able to adapt within certain thresholds, their survival is not assured. Cockroaches will see their way through the next epochs of global warming and global cooling. Species with the intelligence to understand the interconnections, their place in them, and their effects on them deserve their fate if they fail to act appropriately. I believe that ecologists and other scientists have an obligation to educate others, in whatever way they can, about the dangers of a short-term perspective and the importance of sustainable living and actions. Clearly, this is easier said than done in a culture where people either cannot, or chose not to, look beyond their next paycheck, the next budget cycle, or the next election. Steve Stephen P.

If you use the current calculators for water, carbon, or ecological footprint that are available on line, a college first year student sees the connection. I realize those calculators are sloppy and in many ways incorrect, but if I want to teach students about their impact on the world, I will use those calculators as a starting point. If we all lived on our own however many acre plot, it would not change the fact that humans use a disproportionate amount of resources whether in cities or in rural communities in developed countries. At the end of the day, the human footprint, a substitute for habitat loss, is not about cities, it is about the economic and political systems humans create and perpetuate. I think that ecologists should be activists, in our own lives, in our research, and in our classrooms where many of us labor to have the opportunity to do the research that beckons us.

Rob, I think we all agree with the importance of habitat preservation (species conservation, preserving ecosystem functions, etc). And I think we all are on the same page about the disproportionate "tax" on the environment that urban areas have compared to rural areas (or for that matter: developed countries vs less developed countries). Furthermore, I think we can all agree that there is a lot of hype related to most issues -including global climate change. But I feel it worth saying that it might be unproductive and imprudent (in my humble opinion) to make this problem into one of a false dichotomy: into either human habitat destruction or human climate warming. They are both worrisome. And they are both symptomatic of the same problem -a non sustainable life style (economy, or what have you); by me, you, us, them. Furthermore, while there are lots of anthropogenic (as well as non-anthropogenic) processes that result DIRECTLY in habitat destruction NOW, why not be concerned about those effects that will indirectly (and or directly) result in habitat destruction later? Such as our carbon foot print. But perhaps this is all circular. I guess I see this as a spin off of the chicken and the egg argument. If we truly did stop habitat destruction it probably means we are living sustainably, which might then cause carbon in the atmosphere to drop to or below 350 ppm (or some ideal value: see 350.org). Or we could save habitat, not live sustainably, and have weather patterns change ecological patterns and processes in a way that will result in those saved habitats being for a collection of species that are different than originally intended. Or we could destroy habitat, to make carbon neutral bioenergy, to "live sustainably" so that carbon in the atmosphere goes back down to 350 ppm, but species diversity and ecosystem processes still go to pot because we have destroyed habitat (i.e. the means does not justify the end in this scenario). ETC. So really, it is not so much what the impending or most dire problem is per se, but whether our actions result in a sustainable and equitable society for us as well as a viable habitat for the rest of the planet .... But I suppose I am preaching to the choir. -Gene On Tue, Mar 3, 2009 at 10:11 AM, Robert Hamilton <[email protected]> wrote: > Don't know if you want to post a contrasting view, but I'll offer one > up. > > No question that human generated CO2 is causing global warming, in my > opinion.
