Prior to the inception of capitalism, this was also a problem. Production requires resources and generates waste that impacts the ecosystem. The difference now is that it has reached such a massive scale since coal/oil (due to tapping in vast stored energy), that the exponential growth has created an unsustainable level of degradation. Capitalism is not necessary for this.
Capitalism is spewing out its last bitter, vile breath and it's time to move on.
Our system is evolving to consume energy more efficiently to facilitate growth. The flaws of capitalism produce disparity, which throttles growth. The system is recognizing these changes and evolving, via liberalism, to produce a system that can increase the velocity of energy at faster rates. If anything, the evolution of the economic system will hurry production, as the past evolutions have as well (or the system would not allow the reforms to be implemented).
There are other ways to meet the needs of humanity and the environment
Are we going to be pulling hybrid cars and solar panels out of fairies' asses? Are we going to create magic wands? Explain in scientific terms, without ideology, how we can uncouple ecological destruction from production.
On Edit: Awesome way to pull a quote out of context. I said "we cannot simply produce without profit
and negate the effects of production". IOW, selling items at the cost of the resources and work involved (no profit) still necessitates the resources are mined and the energy is consumed. That was a very disingenuous quote pick.
