FTFY: here’s a nature’s nature article on nature (pun intended) [0]. There’s 4 main definition which are exclusive to each others and guess what, your “fix” is within the same definition as GP:
> The whole universe, as it is the place, the source and the result of material phenomena (including man or at least man’s body)
Furthermore I think his point wasn’t about the definition of nature but instead going further on the classic argument “nature will be fine”. Of course universe will always be fine! But your descend may not be part of it. So yes, we should preserve the current equilibrium to preserve ourselves and that’s what this article is all about.
FTFY. We humans are part of nature too.
