Human impacts on or in the environment?

Another thought which illustrates for me the inadequacy of a division between the nature and unnatural, or between nature and society. This one was triggered by a passage from Bill McKibben's book The End of Nature, which is quoted in a Rough Guide to The Earth as suggesting that:
we could let human activity alter the climate so that a hotter-than-before day is essentially a human artifact. But if we take steps to stop altering the climate, a normal cool day is also an artificial event which we have decided to create (Ince, 2007: 272).

Thus, by actively choosing to mitigate global climate change by reducing carbon dioxide emissions we are still creating a human-altered/influenced/managed environment. Through our very presence, self-awareness and power to effect environmental change, whatever we as a species choose to do represents a choice of type of impact in our environment, rather than a choice of level of impact on the environment. This is especially the case given the level of global awareness which has emerged in the past half-century.

This is illustrated on a smaller scale by the management of nature reserves and national parks, which ranges from hands-on management to hands-off 'un-management', and with varying degrees of intervention in between. All of these types of management represent active choices to effect a certain outcome which we have determined is best. And the same is true on the global scale in the case of climate change. Trying to view nature or the environment as a separate domain in which we can choose our level of impact is clearly unrealistic - because of our presence, self-awareness and power to effect environmental change we are always choosing our type of impact. Some form of environmental impact will always result from our actions as a species, since we are a part of our environmental system, not a separate unnatural or social domain.

The question: whether breaking down the division between nature and society in our thinking would lead to a better understanding of the effect that human activity has within our environment?
