I'm watching a show called 'Last Chance to See' in the UK where Stephen Fry and Mark Cawardine are retracing the steps that Mark took with Douglas Adams 20 years ago tracking down some of the most endangered species in the world.
So far only one animal (the Northern White Rhino) might be extinct in the wild but what comes across repeatedly is that humans are trashing this world at an alarming rate partly in order to survive, partly to fund a lifestyle that isn't sustainable (e.g. slashing rain forest to set up palm oil plantations to produce bio-fuel for the western nations or killing rare animals for Chinese medicine), and partly due to territorial disputes. The expanding human population and decreasing animal population is a ticking time bomb.
How so? Destroying life forms that fill important ecological niches is dangerous, but adaptation should account for any hole made by the loss of (de facto) unfit life in the shorter rather than longer term. The only real problem is that the shorter term is still several thousand/ten thousand years, not something humans generally think of a short while, but it's still nothing apocalyptic.
My main ecological concern these days is that global warming will create some positive feedback loops, stop the thermohaline circulation, destroying oceanic oxygenation and giving them to anaerobic, sulfate-using life (H2S = greenhouse gas, also toxic), release methane from beneath the permafrost in the Siberian traps (CH4 = greenhouse gas), and within a few hundred or thousand years revisit the conditions of the P-T extinction, and turn us into Vulcan.
I don't eat red meat either, though.

I've come to the conclusion that it is 1)ethically suspect and 2)economically and ecologically unsustainable in the aggregate, particularly if other civilizations (Earth ones, as opposed to Romulans

) get in on that sweet bacony action.
I'd eat me some replicated pig any day, though. Or long pig, for that matter.
In a hundred years' time the Earth is going to be horrible and we'll be fighting over diverted (polluted) rivers. Yay.
And a bunch of us will die, and balance will be restored to the force, and we'll learn our lesson, and Ra's al-Ghul will say he told us so.
Yes, I'm being a little facetious.

It could, of course, go the other way: with a handful of humans monopolizing the technology and using replicators to build products for pennies and then sell to everyone else for hundreds of dollars. I deeply suspect this is what's wrong with, say, Cardassian and Romulan societies and might explain why their governments are so hostile to humans.
This is a really brilliant, very salient point, dude.
My own thoughts on the subject usually focus on how the workers' paradise is energized. Making antimatter is expensive today, and will always be expensive with "conventional" means of creation (particle accelerators). I've never bought into the magical charge switcher, on the grounds that it is absolutely unbelievable. Even if it could work, I strongly doubt that somehow changing the nature of the quarks within a baryon is going to be much more of an energy-efficient process than banging protons into stuff.
At any rate, I'd love to know the energy consumption of the average replicator. I could probably work something out with the binding energies of the things they make (and then probably multiply times ten, although it's unclear how much waste heat the things make

). If the the replicator's principle of operation is making rearrangements on a
subatomic level, the energies required become even more unmanageably large (Hiroshimas in the kitchen), so I do presume it's a purely chemical process, guided by what'sit-fields and such.
But I would, ballparking, put the energy consumption of the average Earther (including civilian replicators, holodecks, and transporter, if not Starfleet vessels and installations as well, which might be a significant drain on resources as well) as well over ten thousand times the energy consumption of the average American.
That's gotta come from somewhere. I don't think it's coming from nuclear fusion, either terrestrial or solar.
So, in my long-winded way, I wonder if you think that the energy (antimatter production/refining) resources of the Federation might be a significant factor in the development, or at least Earth and the core worlds' developments, of their utopian society.
I've pointed in the past to the Romulans' use of both obsolete (Balance of Terror) and weird, hazardous (various TNG and DS9 episodes) energy sources for their starships--it raised the question, to my mind at least, why are the Romulans using "impulse"-fusion and black hole power plants when they clearly have the technology (Enterprise Incident*) for annihilator reactors, which almost never stop time, mess with time, or serve as incubators for singularity-loving baby-things, and are generally portrayed as higher-performing.
*Assuming D-7s are antimatter-driven, which I believe they almost certainly are, since same- or at most next-generation scout ships use dilithium (TVH) and thus probably antimatter.
I wonder if it's correct to conceive of the Feds, their Klingon semi-puppets, and perhaps the Ferengi and (even) the Cardassians as resource rich (if tech poor in the latter case) in comparison to say, the Romulans, who are technologically advanced but seem to lack access to the good stuff, despite having the engineering knowledge to use it.
