Eh, technology isn't the culprit. We are. Technology is the tool, which is bent to our will. Your pessimism shows your lack of faith in humanity. =)
It's true that as our capabilities increase we must exercise more discretion, restraint, and good judgement, but we have the power to bring great good to the world. Hey, maybe we'll be the architects of life on other planets, maybe we'll transcend humanity into some transhuman consciousness, hell, anything could happen, but only with technological growth. You're so quick to point out the frivolous things we own such as TiVo's, Ipods, and McDonald's as if they are the ultimate symbols of civilization but you completely overlook the amazing things we have now, from electricity to advanced medicine to incredibly diverse cuisine to the exploration of space.
Also, global warming isn't destroying the Earth... it's definitely a serious problem that must be addressed and can have serious ecological ramifications but I assure you, we will still be here, and so will life on Earth. We're not making it uninhabitable, we're just making it less hospitable to organisms that have adapted to current conditions and aren't necessarily adapted to newer conditions... Far more serious challenges to life on Earth have been met and overcome, and it's continued to increase in complexity and wonder. Check out the IPCC report... it's grim, but it isn't nearly as sensational as your claims.
Hey, here's some ecological damage brought on by hunter-gatherers. Notice how major extinctions of many large creatures outside of Africa seem to coincide with the arrival of hunter gatherer's? It's because while animals in Africa had the benefit of evolving alongside humans, when humans took their hunting techniques outside of Africa they were quick to wipe out most of the larger animals in the area... Yeah... population boomed then busted... talk about sustainability. The difference might just be scale, but you're making a rather arbitrary distinction here by saying pre-agricultural stone age technology is the only sustainable level of technology. I would argue that humans are far too successful and selfish to be sustainable without conscious effort... and hey, it's with our scientific method, educational systems, and advanced research techniques that allow us to understand the forces that shape our world and allow us to make the decisions that will promote sustainability. It's not like hunter gatherer's had any idea they would have such a large ecological effect...
Progress isn't relative... there are many ways you can measure progress... though this is a tautological argument. For example, you can measure progress by the amount of energy that humanity is able to harness, which is quite useful in that it may measure our capabilities and much of the definition of life is based on the use of energy to maintain homeostasis, and we're certainly better at that nowadays... consider air conditioning, medicine, well formulated diets, etc. Early on, we could harness only the energy of our own labour... agriculture and domestication vastly increased populations and subsequently the total energy of our labour as well as giving us access to domesticated animals which could contribute their energy. We've had labour, fire, electricity... we've had hydro power (mills, dams), wind power (sails, wind turbines), fossil fuels, etc. It's been exponentially increasing... tell me that's relative.
I just find it funny that your justification of primitive life being superior to civilized life has changed since you've come here... Is this the last thing to refute? Or will you back into another corner? Or will you simply ignore what we've said, maintaining that you're better informed without giving us your sources so that we might be just as informed?
