5. Since the publication of Rachel Carson’s book, Silent Spring in 1962, what laws have been enacted that have helped bald eagles recover?…
Agriculture was first started around the year 8,000 B.C.E. in Mesopotamia. There the plants grew along with food so humans could eat them. These first parts of farming faced many challenges with insects and pests eating away their crops. During the era of 1000 B.C.E. the Chinese began experimenting with elements such as mercury and other compounds to contain the insects. Other civilizations would use chemicals to contain pests. The usage of chemicals has occupied agriculture, and even more recently in the 1940’s inorganic substances composed of various elements were heavily used to contain the insects affecting the crops. The growth of many synthetic pesticides occurred during this time, the most common one was DDT. DDT was used the most…

They lived in two different areas of the world and their habits were different. The reason why they became extinct are two different stories. There are differences between the Dodos and Passenger Pigeons such as are how they became extinct, in their body size, and where they lived.…

Imagine you’re a spotted owl mother who just hatched her 4 newborn owlet children. Obviously you’re thrilled to be starting this new chapter of your little owl life with a brand new family but you’re also shadowed with the fear of the young ones safety. The Great Horned and Barred Owl are stalking your new members for a late night snack and the opportunity to run you out of your home like the true savages they are. As their numbers in population increase, your own kind becomes more threatened. Once efforts to expand the Northern Spotted Owls habitat are increased, shared space with the Barred Owl is further limited and protection of their young is improved, then their population will soon increase. That…
The bald eagle (Haliaeetus leucocephalus), our national bird, is the only eagle unique to North America. The bald eagle's scientific name signifies a sea (halo) eagle (aeetos) with a white (leukos) head. At one time, the word "bald" meant "white," not hairless. Bald eagles are found over most of North America, from Alaska and Canada to northern Mexico. About half of the world's 70,000 bald eagles live in Alaska. Combined with British Columbia's population of about 20,000, the northwest coast of North America is by far their greatest stronghold for bald eagles. They flourish here in part because of the salmon. Dead…
A snowy owl will live out the entire course of its life in the open artic in most cases, while others will migrate out of the arctic tundra. They will hunt, eat, mate, reproduce, and die where they reside. The largest bird in the artic, by a weight of up to six pounds, the snowy owl stands roughly two feet tall (National Georaphic). The snowy owl is a fearless hunter and strong protector. The snowy owls are diurnal, hunting mainly during the day unlike most species of owls that tend to be nocturnal. They mainly live in isolated and remote regions of the greater north; this protects them from human interaction. Snowy owls are immensely protective over their home, hunting grounds, and offspring.…

Owl pellets can provide evidence of the owl’s dietary habits and its role in its environment. Owl pellets have been used for scientific study of small mammals and their distribution. Since the owls are collecting, the scientist must locate the owls to obtain the pellets, and then study the skulls and bones of small prey living in an area. From these bones the prey species can be counted and identifies. These owls play in the role of limitating the population size of its prey. They prey species that is most plentiful in the area will be the species most likely to be captured and consumed by the owl.…
Barn owls are beautiful and majestic birds. With its eerie, ghost-like appearance, the barn owl is easily recognisable. Although not often seen, a barn owl can be found sitting over a field hunting mice and rats. Barn owls have acquired their name from roosting in barn lofts but can also be found in caves, and hollows in trees. Each day the environment becomes more contaminated by chemicals and poisons. The barn owl is threatened by these pollutants and has been negatively impacted.…

Prose exposes numerous straw man arguments with To Kill a Mockingbird. Prose critiques the novel in a confident, yet slightly harsh manner. She believes that the novel could’ve been different if there was just a bit more detail. Prose interprets To Kill a Mockingbird in a way that focuses on prejudice and racism.…
Casida , a professor of Environmental Science at the University of California in Berkeley, when observing pesticide-environment interactions reported; “A large number and great variety of pesticides… have reproductive and endocrine disrupting effects in mammals and wildlife” (Casida, 492). Many pesticides cause hormone levels within animals to become unbalanced, affecting sexual organs and reproductive systems, causing them to have unnatural issues. Such effects range from small, unnoticeable changes in the physiology and behavior of a species to destroying bird embryos to permanently altered sexual differentiation. In a recent case, bald eagles were at the top of the endangered species list. As a result of exposure to the pesticide DDT, the eggshells of the eagles became thin, causing them to break during the incubation period. DDT was banned in the late 1970’s and the bald eagle populations have been rising since (Bald Eagles, Sea to Shining Sea). As one could imagine, if DDT had not been regulated and banned in the United States, then the country would have lost its majestic national bird to pesticide poisoning. This shows that pesticides are extremely harmful to wildlife and can cause detrimental damage not only to the animal itself, but to its…
