I believe adamantly in the need for sustainable practices across the spectrum.
A process that follow a periodic cycle has an awesome feature that a linear one does not: it doesn't end.
There are limits.
There are palpable, hard limits.
Are you suggesting that the Earth has a finite volume? Lies! It's all lies! Growth can be and will be infinite! You crazy earthling!
Joking aside, I really like your description of the problems.
Environmentalism is political, commercial, ethical - but not scientific. The former three are all traits I can readily relate to it, and through them it affects everything it touches. Scotland as a country has been striving to be at the forefront of "green technology" for a while now, but all it is is a different way of making a profit. It has had some positive effects on our world, and maybe one day we'll even find a way to collectively ensure waste energy is minimised, or to form a complete energy cycle that can return to the basics of using solar energy to power growth without relying on processes that take anywhere from months to mellenia to give us the raw material we want.
Why isn't it political, commercial, ethical and scientific?
