Isn't formally celebrating Nature a contradiction?

On the back of a flyer for a nature festival are the "stalls and sponsors."

It's can't really be a festival of "Nature" as everything is already Nature like the sunrise and our beating heart.

Surely this is rather a festival of whatever crumbs are metered out by Capitalism and the Owners of industry. In fact it's the antithesis of Nature as Nature is what is left after you remove Capitalism. I may purchase a hip replacement from a Capitalist but the original hip comes from, belongs to and returns to Nature. Sad days when "festivals" like this exist.
