    The tawny owl, otherwise known by its scientific name, Strix Aluco, or simply the brown owl, is a bird native to much of Eurasia. The tawny owl is known for it’s small, compact body, as well as its brown colorations as it is named for. This specific breed of owl is known in folklore to have an uncanny sense of sight during the night time, however this has been disproven through the work of Selig Hecht and Maurice Pirenne (Hecht and Pirenne, 1940). It was actually proven through their work that the tawny owl, however able to see a more broad range, has a similar to our own vision at low light visibilities. Much of this was thought to be true, along with the myth that this specific species of owl brings bad luck and death because of the fact that the tawny owl is a nocturnal bird of prey, and it possesses a very well known and sinister call.…

    The mere mention of the creature 's name brings shudders to loggers and some local inhabitants, fear over its existence has incited rallies, garnered the attention of three government agencies, and caused people to tie themselves to trees. On April 2, 1993, President Bill Clinton embarked on a quest to settle a long-standing battle. The environmentalists on one side, and their attempts to protect natural resources, and the timber industry 's desire for the same on the other.

    Barn owls usually cough up their food that they swallowed whole – they then barf up bits of fur and bone which are known as owl pellets. Barn Owls don’t hoot they screech instead (Tawny Owls hoot). Barn Owls breed faster when mice have plagues or illnesses. Other food that they eat may be small to baby rabbits, bats, frogs, lizards, birds and insects.

    In the fourth chapter, Carson talks about how water is one of our most important natural resources but we keep contaminating it with pollutants. She states that the pollutants come in many forms such as radioactive waste from laboratories, domestic waste from cities, chemical waste from factories, and fallout from nuclear explosions and chemical sprays. She points out that some chemicals are purposely added to water to try to “destroy plants, insect larvae, or undesired fishes (pg. 40).” She states that some pollutants can travel through the soil and into groundwater, which she describes as one of the most disturbing water pollutants as all water on Earth was once groundwater. She states that pollution of groundwater is essentially pollution of the entire Earth. In the fifth chapter, Carson talks about how chemicals affect soil. The pesticides seep into the soil, then travel into plants, which humans and other animals later eat. Carson points out that some of the insecticides that are used to kill pesky insects can also kill beneficial insects who have the essential function of breaking down organic matter (pg. 56). It can also prevent necessary fungi from forming at the roots of trees--fungi that helps the tree extract nutrients from the soil. In one study, the use of many pesticides prevented nitrogen-fixing bacteria from growing at the roots of vegetable plants (pg. 56-57). A group of specialists from the Syracruse University stated that “a few false moves on the part of man may result in destruction of soil productivity and the arthropods may well take over (pg.…
