There is no such world, and no reason to consider the remote possibility as affecting current relations,
There are quite a number of people considering, even assuming it is the likely part of the expansion of homo sapians.
and no reason to denigrate affection for one's home and landscape.
There is no reason to denigrate that affection, but no reason to take it seriously.
Meanwhile, there is no "scientific reason" to treat the natural world as being some kind of simplistic, mechanical, clockwork writ large.
I agree. But I think that assumption is made by those who are leaping into the genetic modification of foods, for example. They seem to think they are tinkering with a machine simple enough to preclude missing a wide array of effects. The people who are doing this tinkering know, or at least should know, that they are a part of organizations - corporations - that control their own governmental oversight to a degree that is more than mildly conflict of interest, especially after two Bushes, one Reagan and yes, even one Clinton. I see their confidence as precisely lacking the 'scientific reason' - all connotations intended - that you mention, and nevertheless I am quite sure I would be considered a Cassandra or irrational if I were to open a thread in this forum critical of GM foods and other gm, even if my criticism was in the same spirit as your dismissal of the clockwork image.
I see this as a threat to my home. Slack oversight on nanotechnology also strikes me this way, precisely because the world is being treated as very simple, an idea implicit in the confidence of these organizations.
Secular is not a synonym for idiot.
No, of course not. Some of my best friends are secular - and not idiots - through and through. (pardon, but I couldn't resist the irony of that sentence construction). But at root a secular humanism that accepts only knowledge via peer reviewed scientific research (positively reviewed, that is), has its hands tied when it comes to issues like 'home.'
