In the words of this beautiful canticle, Saint Francis of Assisi reminds us that our common home is like a sister with whom we share our life and a beautiful mother who opens her arms to embrace us. This sister now cries out to us because of the harm we have inflicted on her by our irresponsible use and abuse of the goods with which God has endowed her. We have come to see ourselves as her lords and masters, entitled to plunder her at will.
The CIA’s Most Highly-Trained Spies Weren’t Even Human
Jump to navigation. Carson, a renowned nature author and a former marine biologist with the U. Fish and Wildlife Service, or FWS, was uniquely equipped to create so startling and inflammatory a book. A native of rural Pennsylvania, she had grown up with an enthusiasm for nature matched only by her love of writing and poetry.
The educational brochures she wrote for FWS, as well as her published books and magazine articles, were characterized by meticulous research and a poetic evocation of her subject. Carson was happiest writing about the strength and resilience of natural systems. Although she rarely used the term, Carson held an ecological view of nature, describing in precise yet poetic language the complex web of life that linked mollusks to seabirds to the fish swimming in the ocean's deepest and most inaccessible reaches.
DDT, the most powerful pesticide the world had ever known, exposed nature's vulnerability. Unlike most pesticides, whose effectiveness is limited to destroying one or two types of insects, DDT was capable of killing hundreds of different kinds at once. Its inventor was awarded the Nobel Prize. When DDT became available for civilian use in , there were only a few people who expressed second thoughts about this new miracle compound.
One was nature writer Edwin Way Teale, who warned, "A spray as indiscriminate as DDT can upset the economy of nature as much as a revolution upsets social economy. Ninety percent of all insects are good, and if they are killed, things go out of kilter right away. The magazine rejected the idea.
Some of the attacks were more personal, questioning Carson's integrity and even her sanity. Her careful preparation, however, had paid off. Many eminent scientists rose to her defense, and when President John F. As a result, DDT came under much closer government supervision and was eventually banned.
Carson had made a radical proposal: that, at times, technological progress is so fundamentally at odds with natural processes that it must be curtailed. Conservation had never raised much broad public interest, for few people really worried about the disappearance of wilderness. But the threats Carson had outlined—the contamination of the food chain, cancer, genetic damage, the deaths of entire species—were too frightening to ignore. For the first time, the need to regulate industry in order to protect the environment became widely accepted, and environmentalism was born.
Carson was well aware of the larger implications of her work. But man is a part of nature, and his war against nature is inevitably a war against himself? And equally inspiring is the example of Rachel Carson herself. Against overwhelming difficulties and adversity, but motivated by her unabashed love of nature, she rose like a gladiator in its defense.
We will keep you informed with the latest alerts and progress reports. Although they will probably always be less celebrated than wars, marches, riots, or stormy political campaigns, books have at times been the most powerful influencer of social change in American life. Rachel Carson examining a specimen. Thirteen years later, in , Carson's interest in writing about the dangers of DDT was rekindled when she received a letter from a friend in Massachusetts bemoaning the large bird kills that had occurred on Cape Cod as the result of DDT sprayings.
The use of the pesticide had proliferated greatly since , and Carson again tried, unsuccessfully, to interest a magazine in assigning her the story of its less desirable effects. By , Carson was a best-selling author, and the fact that she could not obtain an assignment to write about DDT is indicative of how heretical and controversial her views on the subject must have seemed.
Having already amassed a large quantity of research on the subject, however, Carson decided to go ahead and tackle the issue in a book. Thanks for signing up. You'll receive your first NRDC action alert and update email soon.

There would be a rustle of oily black feathers as a raven settled on the window ledge of a once-grand apartment building in some Eastern European capital. The bird would pace across the ledge a few times but quickly depart. In an apartment on the other side of the window, no one would shift his attention from the briefing papers or the chilled vodka set out on a table. Nor would anything seem amiss in the jagged piece of gray slate resting on the ledge, seemingly jetsam from the roof of an old and unloved building. Those in the apartment might be dismayed to learn, however, that the slate had come not from the roof but from a technical laboratory at CIA headquarters in Langley, Virginia. The raven that transported it to the ledge was no random city bird, but a U.

Animal welfare is the well-being of non-human animals. Formal standards of animal welfare vary between contexts, but are debated mostly by animal welfare groups, legislators, and academics. Respect for animal welfare is often based on the belief that nonhuman animals are sentient and that consideration should be given to their well-being or suffering , especially when they are under the care of humans.

Bed bugs have made a major comeback in the U. The rebound in recent years was probably due to multiple factors, including less potent insecticides, global travel, and a loss of vigilance practiced in years past. Whatever the reasons, bed bugs are again part of everyday life, with infestations common in homes, apartments, hotels, dormitories, schools and shelters. They also occur in hospitals, nursing homes, libraries, theaters, offices, municipal buildings, and on public transportation— wherever there are people there can be bed bugs. Bed bugs are small, brownish insects that feed solely on the blood of animals. It has done so since ancient times; bed bugs are mentioned in medieval European texts and classical Greek writings back to the time of Aristotle. Their coloration is similar to an apple seed although their size is closer to a lentil.
Pigeon photography is an aerial photography technique invented in by the German apothecary Julius Neubronner , who also used pigeons to deliver medications. A homing pigeon was fitted with an aluminium breast harness to which a lightweight time-delayed miniature camera could be attached. Neubronner's German patent application was initially rejected, but was granted in December after he produced authenticated photographs taken by his pigeons. He publicized the technique at the Dresden International Photographic Exhibition, and sold some images as postcards at the Frankfurt International Aviation Exhibition and at the and Paris Air Shows. Initially, the military potential of pigeon photography for aerial reconnaissance appeared interesting. Battlefield tests in World War I provided encouraging results, but the ancillary technology of mobile dovecotes for messenger pigeons had the greatest impact. Owing to the rapid perfection of aviation during the war, military interest in pigeon photography faded and Neubronner abandoned his experiments.
Authored by: Carol Huneycutt, National WWI Museum and Memorial Teacher Fellow. ESSENTIAL QUESTIONS: • What role did animals play in the successes and failures of World War I? Groups may choose to focus on an animal type, related to the animal such as a horse saddle, a dog collar, a pigeon carrier, etc.
This article reviews the use of non-human animals in biomedical research from a historical viewpoint, providing an insight into the most relevant social and moral issues on this topic across time, as well as to how the current paradigm for ethically and publically acceptable use of animals in biomedicine has been achieved. The use of non-human animals in biomedical research has given important contributions to the medical progress achieved in our day, but it has also been a cause of heated public, scientific and philosophical discussion for hundreds of years. This review, with a mainly European outlook, addresses the history of animal use in biomedical research, some of its main protagonists and antagonists, and its effect on society from Antiquity to the present day, while providing a historical context with which to understand how we have arrived at the current paradigm regarding the ethical treatment of animals in research. Animal experimentation has played a central role in biomedical research throughout history. For centuries, however, it has also been an issue of heated public and philosophical discussion.
