It is quite understandable that people who rely on feelings more than reason to form their spiritual beliefs would deify nature. It is easier -- indeed more natural -- to worship natural beauty than an invisible and morally demanding God.
What is puzzling is that many people who claim to rely more on reason would do so. Nature is unworthy of worship. Nature, after all, is always amoral and usually cruel. Nature has no moral laws, only the amoral law of survival of the fittest.
Why would people who value compassion, kindness or justice venerate nature? The notions of justice and caring for the weak are unique to humanity. In the rest of nature, the weak are to be killed. The individual means nothing in nature; the individual is everything to humans. A hospital, for example, is a profoundly unnatural, indeed antinatural, creation; to expend precious resources on keeping the most frail alive is simply against nature.
The romanticizing of nature, let alone the ascribing of divinity to it, involves ignoring what really happens in nature. I doubt that those American schoolchildren who conducted a campaign on behalf of freeing a killer whale (the whale in the film "Free Willy") ever saw films of actual killer whale behavior. There are National Geographic videos that show, among other things, killer whales tossing a terrified baby seal back and forth before finally killing it. Perhaps American schoolchildren should see those films and then petition killer whales not to treat baby seals sadistically.
If you care about good and evil, you cannot worship nature. And since that is what God most cares about, nature worship is antithetical to Judeo-Christian values.
Nature surely reflects the divine. It is in no way divine. Only nature's Creator is.
