The following article does a compelling job (IMHO) of demonstrating the wholesale disconnect between economic discourse and ecological realities. I've posted an excerpt that, I believe, lays this out. But please, read the article in its entirety, as it is much more deeply nuanced than this one excerpt.

Technology is more endogenous than modern growth theory postulates.The subject of growth is so central to the science of economics that generally-held convictions about it may be called upon to characterize socioeconomic evolution in broad brush endeavors of macrohistoric periodization. As one might expect, such “signs of the times” doctrines are Oedipal in nature. Each must kill its progenitor before it can mount the throne and fulfill its destiny.
Since the 1980s, the so-called endogenous growth theory (EGT) has held sway. It is distinguished from its predecessors by “endogenizing” variables formerly considered to be exogenous. Through their simultaneous interactions, all the variables are solved within a mathematical formulation of long-run economic expansion, typically captured by growth in productivity (output per capita). Particularly noteworthy is the “endogenization” of technological progress and demographic expansion.
Concerning technology, EGT symbolically eliminated its exogenous forerunner by permanently associating it with the derisive sound bite -- “manna from heaven;” that is, for considering technological progress an unfailingly delivered gift (as if from a deus ex machina) rather than the result of a complex interplay among all demographic and economic variables. Ironically, EGT also has a quasi-religious belief in inevitable progress.
As much as it gropes to incorporate ecological considerations, the reigning growth theory is impervious -- sometimes overtly hostile -- to recognizing the entropy law’s importance in the economic process. It essentially denies that humans cannot create something out of nothing. It embraces creatio ex nihilo in a universe where creatio ex materia is the fundamental law.
By focusing on an enlarged concept of capital (called “generalized capital”), which includes knowledge and monetary gains from research and development, EGT heroically bans diminishing returns, i.e., the gradual disappearance of economic growth opportunities. The adherents (most of whom had topped off their wisdom tanks at unregenerate neoclassical filling stations) believe that, as long as human ingenuity prevails, the flow of new ideas into the global network of ever more efficient industrial assets -- coupled with an insatiable entrepreneurial spirit -- will ensure permanent growth.
In light of the second law of thermodynamics, EGT’s technical progress is also exogenous because it treats ideas about products and techniques of production as if they were independent from the terrestrial sphere’s overall physical condition. EGT redefined “manna from heaven” but remained dependent on it, abetting the insane theology whereby “growth forever” is possible in a thermodynamically closed system. In short, EGT misses and obfuscates the most essential.
The accumulation of entropy (unidirectional and irreversible), owing to the depletion of free energy contained in matter implies that the errant focus of scientific interest (always finding free energy for a purpose) is on its way to be statistically defeated. Matter may have an infinite number of qualities, but its growing dispersion decreases the probability that any particular set of qualities can be used without increased amounts of energy and matter. Importantly, the potentially unlimited energy pent up in matter cannot pick up the tab alone. More energy means increased use of matter, increasing the share of bound energy in our ecological niche.
Believing in the independence of technical innovativeness is the same as considering information a free variable that can undo entropic accumulation. The approach inadvertently equates entropy with ignorance and, hence, unconsciously assumes a loophole in the second law, the existence of perpetual motion machines.
The phsyico-chemical drain imposed on terrestrial matter will tend to frustrate particular solutions to the opportunistic acquisition of free energy from the global environment. Eternal substitution of one material for another is a sheer thermodynamic impossibility. But when and how will this already accessible rational insight begin to shape thinking and behavior and become the primal empirical paradigm of global self-organization is an indecipherable mystery.
END OF EXCERPT
In summary, by ignoring the second law of themodynamics and by considering parts of ecological-economic systems as representative of the whole, modern economic discourse seems to be setting us up for a grand fall.
