The continued degradation of the environment will cause immeasurable loss. I mean this literally - and that's why it's so hard to debate this issue with anyone who will take a hard-lined capitalist-logic-based approach.
Well, Sego, I take a "hard-lined capitalist-logic-based approach", but I don't I'm hard to debate with!
You, like most of the posters here, seem to see capitalism and environmental protection as incompatible.
Some of us understand that capitalism and environmental protection can both advance in harmony if we gave serious respect to propery rights.
Free market capitalism under a system of property rights allows for a tremendous creation of weath, which free people can spend on the things they value. Vast amounts of people value a clean, protected and preserved environment. Groups that seek to preserve the environment by purchasing property for preservation have had great results, for example.
Free market capitalism also generates cleaner and more efficient technologies which allow us to produce more stuff while doing less environmental damage.
I could go on and on, but please don't make the mistake of believing that we can't have our cake and eat it too. The environmentally cleanest places in the world are the most free places, places that operate, for the most part, on free market capitalism.
