This drives me crazy:
[QUOTE=chowder]
The soil is poisoned, the seas, rivers, lakes and streams of this fair planet are polluted and the skies themselves harbour all manner of noxious gases. All this because of our meddling with nature itself.
Nature has it right, she needs no, or at least, minimal interference from us and yet we presume to know better.

Nature is not, as your rhetoric here would imply, some being that exists (and has a gender!) idependent of humanity. Humans are part of nature. I am part of nature. That poison in the soil? Every bit as “natural” as any other combination of elements that exist. If I cut down a tree in my backyard, this is not “wanton vandalism;” this is a natural, process ultimately no different from the perspective of “nature” as a whole than when a tree is destroyed by a bolt of lightning. If a species of bird goes extinct, if a whole field of pretty flowers is replaced by a shopping mall, nature doesn’t shed a poetic tear. Nature doesn’t give a shit, because “nature” isn’t a person; it’s a process. That lifeless uninhabitable floating ball of dust you posit? From an objective perspective, from the perspective of the personified “nature” you’ve created - that ball of dust is no better or no worse than what we have now.
What is good, what is bad, what is positive, what is negative - it’s all defined by the observer. From our standpoint as humans, it’s bad if that field of flowers is wiped out because we enjoyed looking at them, or because they played a role in the local ecosystem and if they are disturbed it will affect us in a negative way. It’s not bad because it’s “unnatural;” the shopping mall is just as “natural,” whatever that means, as the flowers were. It’s bad because of how it affects humans (and also, potentially, good because of how it affects humans), and that’s really all it’s our responsibility as a species to worry about, I think.
That’s the basis of my answer to the OP, actually. I think that the secular approach is to pursue, as it were, the maximization of human happiness. Most religious approaches tend to emphasize sacrificing some amount of happiness in this world for the promise of reward in the next. The nonreligious approach to the future would seem to be - let’s build a world in which everyone can be as happy as possible. Let’s reduce violence and killing to as close to zero as possible, since the dead and the wounded are rarely happier than the living and the healthy. Let’s reduce the impact of disease, poverty, and even aging, for the same reason. Let’s afford ever-greater access to entertainment, art, and just generally cool stuff. Let’s make sure there are always fields of flowers around for those who want to look at them, but always shopping malls for those who want to use them. Let’s make it so that we can have sex with who we want, with no threat of retribution in this life or another. Obviously, no person can ever have everything he or she wants - some of those wants will conflict with the wants of others, and so everything will have to be carefully balanced - but we can absolutely increase the overall level of human contentment to an enormous degree by actually working toward that goal and not toward building a kingdom of god on earth, or whatever.
