Anyone who is good at english and reading?

I have a project where I need to make up a whole theme that has to do with nature. I have a few quotes that I want the theme to have to do with. They are "landscape is what we allow in through the doors of perception", "all the value it had to me now was the usefulness it could furnish toward comping the safe piloting of a steamboat", "I could not unlearn the dimsal numbers - the tallies of pollution and population and poverty that foretold catastrophe", "The power to produce this delight, does not reside in nature, but man, or in a harmony of both", "but beautiful as it is, one might have a the sense of confinement there". These are all quotes about nature, and I want to be able to have an overall theme that they would fit in. PLEASE HELP :)
