.......You sound like the sort who thinks that not only isn't the glass half empty, it doesn't even exist!
Actually, I'm quite a nature nut. While enjoying nature and seeing beauty in it's complexity I'm not naive about it coldhearted survival driven manner. Aesthetics being subjective and often a matter of perspective makes it unsolid footing for any arguement of Divine goodness. Under a microscope illusions (albeit nice ones)tend to fade. The sensation of belonging to the earth is better understood from an evolutionary position.
