So many people are worried about how technological advances are ruining the environment. What many often forget is that technology is also the answer (unless you want to go back to a hunter-gather lifestyle and I hear that the drum/smoke-signal bandwidth really sucks, it's takes forever to download the latest movie.)
We're in a race - computational speed, new materials, new efficiencies versus the rate in which we're polluting the environment. Many things make me optimistic: photovoltaic paints for one - and now processing power so efficient that it can be solar powered. Wow. We may win this race after all.
You insensitive clod! Smoke signals release carbon into the atmosphere!
