We do things every day that don't necessarily agree with nature and certainly wouldn't fall into the "leave nature alone" category.I don't really like messing with nature. I like to let things go how they go. Yes, even if that means humans(who are a part of nature) are directly responsible for the demise of a species. I'd rather leave nature alone--at least today. Maybe someday when we are more educated on the pros and cons of manipulating nature could we take on these kinds of things.
