From The Environmental Debate: A Documentary History
"By the end of the nineteenth century, industrial wastes were beginning to have a deleterious effect on the water quality of rivers around the country. Tucked away in section 13 of the Rivers and Harbors Act of 1899—which was primarily an appropriations bill allocating funds for dozens of river and harbor construction, repair, and preservation projects—was a prohibition against dumping refuse in navigable waters, making it the first federal antipollution law. It is interesting to note that the first colonial antipollution statute also concerned the dumping of garbage in harbors"

"The first national effort to set aside forest lands was undertaken during the administration of James Madison. It was a pragmatic act to ensure the fledgling U.S. Navy of adequate timber supplies for shipbuilding. Madison's secretary of state, John Quincy Adams, who as president would later expand the nation's forest reserves, was undoubtedly a supporter of the act."

From The Environmental Debate: A Documentary History
"Three of the first four U.S. presidents—George Washington, Thomas Jefferson, and James Madison—were Virginia planters who devoted a great deal of thought, study, and effort to the development of techniques for making their land more productive. While they carefully rotated crops and fields, they rejected the use of high-priced fertilizers until rising land prices made such expenditures practical. They were all active members of the American Philosophical Society, one of whose primary goals was the furtherance of scientific agriculture."

To go into solitude, a man needs to retire as much from his chamber as from society. I am not solitary whilst I read and write, though nobody is with me. But if a man would be alone, let him look at the stars.

The shore is irregular enough not to be monotonous. I have in my mind’s eye the western, indented with deep bays, the bolder northern, and the beautifully scalloped southern shore, where successive capes overlap each other and suggest unexplored coves between.

Dear Mr. Pesonen:
I believe that you are working on the wilderness portion of the Outdoor Recreation Resources Review Commission’s report. If I may, I should like to urge some arguments for wilderness preservation that involve recreation, as it is ordinarily conceived, hardly at all.

Misuse of scientific and technical knowledge presents a major threat to the existence of mankind. Through its actions in Vietnam our government has shaken our confidence in its ability to make wise and humane decisions. There is also disquieting evidence of an intention to enlarge further our immense destructive capability.
