	Environmentalism - Wikipedia, the free encyclopedia
		Environmentalism is the philosphical concern that humans may be damaging the natural environment, and that this damage may adversely impact people.
		In modern times, environmentalism has spawned the environmental movement, which stresses issues such as industrial and other pollution, species extinction, preservation of biodiversity, waste management and recycling, global climate change, ozone depletion, and genetically engineered organisms.
		The Environmental Movement (a term that sometimes includes the conservation and green movements) is a diverse scientific, social, and political movement.

	Cancer Causes, Risks, and Environmental Factors from Novartis Oncology
		It often is difficult to point to a single cause of a cancer, but certain environmental factors are strongly correlated with the occurrence of particular cancers.
		Environmental factors cause mutations and also affect the rate of abnormal cell growth.
		Environmental factors change both genes and the growth properties of cells that may lead to the development of cancer.

		The proposed mechanism is that exposure to an environmental factor, on the basis of genetic risk factors, will lead to the development of a specific syndrome.
		Environmental factors may contribute to apoptosis or cell accumulation, as in malignancies or autoimmune diseases.
		An excellent example for a prototype of a disease where the environmental factor was overcome is coeliac disease -- avoiding ingestion of gluten prevents both the clinical and immunologic features of the disease.

	Environmental Factors in Cancer Development Information on Healthline
		Originally, the term "environmental cause of cancer" was used to refer to all cancers that were not caused by hereditary or inherited factors.
		External environmental causes of cancer refer to factors in the environment such as environmental pollutants that increase risk for cancer.
		Epidemiologists are scientists who research and identify factors which are common to cancer patients' histories and lifestyles, and then evaluate those factors within the context of current biological and disease causation theories.

	Environmental scanning - Wikipedia, the free encyclopedia
		This allows the firm to act quickly, take advantage of opportunities before competitors do, and respond to environmental threats before significant damage is done.
		Environmental scanning usually refers just to the macroenvironment, but it can also include industry and competitor analysis, consumer analysis, product innovations, and the company's internal environment.
		opposition strategy - try to influence the environmental forces so as to negate their impact - this is only successful where you have some control over the environmental variable in question

	Environmental Factors and Middle Ear Infection in Infants
		Though the most cautious parents may not be able to prevent the disease entirely, research indicates there are environmental factors that can predispose children to a greater risk of ear infections.
		Although the use of secondary heating sources could not be conclusively tied to otitis media infections, other factors, including attending a day care center, history of asthma and allergies, and birth in the fall, were associated with recurrent otitis media cases.
		Interestingly, this last factor has a significant impact on the recurrence of otitis media because children born in the fall spend their first six moths of life in the seasons with higher ear infection rates.

		There is, however, increasing documentation that environmental factors may affect both the susceptibility of children to respiratory infectious disease and the duration of disease.
		Schwartz and Weiss[10] demonstrated that bronchitis was associated negatively with serum vitamin C levels and that symptoms of wheezing were associated negatively with serum vitamin C and niacin levels.
		An important nutritional factor for children that protects against respiratory infection is breast-feeding, as has been proven in several studies (for a review see reference 11).

	Exploring Autism (Site not responding. Last check: 2007-11-01)
		Evidence from many studies suggests that inherited factors are largely responsible for the occurrence of autism related disorders.
		In addition to having the right combination of autism-related genes, exposure to certain environmental factors might be necessary for autism to develop in some individuals.
		By focusing on the study of genetic factors and determining their underlying mechanisms, researchers may be better able to pinpoint environmental factors that contribute to autism.

	Sociological and Environmental Factors of Criminal Behavior
		There are several factors that impact an individual’s destiny and through various studies, explanations, and theoretical models it becomes very apparent that one isolatable factor is nearly impossible to distinguish.
		There are several important theories that do not advocate the influence of heredity or environmental factors over one another but in fact display the importance of their interaction in determining an individual’s behavior.
		This illustrates a strong correlation of genetics and criminal disposition but it also indicates the relative importance of environmental factors as well; environmental factors influence criminal behavior, which explains why there is not a 1:1 correlation of genetic disposition and criminal behavior.

	Schizophrenia.com - Schizophrenia Causes and Prevention
		These lines of research are beginning to converge: brain development disruption is likely the result of genetic and/or environmental stressors early in development (during pregnancy or early childhood), leading to subtle alterations in the brain that make a person susceptible to developing schizophrenia.
		Environmental factors later in life (during early childhood and adolescence) can either damage the brain further and thereby increase the risk of schizophrenia, or lessen the expression of genetic or neurodevelopmental defects and decrease the risk of schizophrenia.
		An example of this theory with regard to schizophrenia is a recent research study that indicated that people who had multiple copies of a version of the COMT gene and who smoked marijuana had a 1,000% increase in their risk of developing schizophrenia.

	Environmental factors cause cancers
		Statistical modeling was used to estimate the relative importance of heritable and environmental factors in causing cancer at 11 of those sites.
		The scientists did not identify what environmental factors may lead to cancer, but noted that a poor diet, lack of exercise, radiation and pollution are likely culprits, along with lifestyle choices like smoking.
		"Environmental factors are more important than gene factors, and that's important to remember, especially since everyone thinks that everything is solved now that we have the human genome in our computers," said Paul Lichtenstein of the Karolinska Institute in Stockholm.

	Environmental Factors - The ALS Association
		As no one would propose to give a known or potentially toxic substance to people on purpose, any study of the potential role of environmental or dietary factors in ALS must be by the methods of epidemiology.
		One of the first clues that ALS might involve an environmental factor was obtained on the island of Guam in the Pacific, where an unusually high proportion of people over the past century have developed symptoms similar to ALS as they age.
		A recurring idea about environmental influences on ALS is that a virus is responsible for the condition.

	Clinical Trial: Urban Environmental Factors and Childhood Asthma
		The purpose of this study is to determine the way environmental factors affect immune system development and symptoms of asthma in inner city children.
		Study hypotheses: 1) Environmental factors in the inner city adversely influence the development of the immune system to promote cytokine dysregulation, allergy, and recurrent wheezing by age 3.
		Evidence suggests that environmental factors unique to the inner city, such as certain allergens, infections, and pollutants, may affect immune system development and lead to the development of more severe asthma in early childhood.

	ATSDR - CSEM - Environmental Triggers of Asthma: Environmental Factors, Sources and Pollutants
		Under these circumstances, there is usually no latency from initial exposure to the asthma attack and the patient usually returns to his or her preexisting baseline on removal from exposure.
		In dry climates, such as Los Alamos, New Mexico, only 30% of children were sensitized to dust mite allergens, but the majority were sensitized to cat dander allergens, which was the most important factor associated with asthma in that population.
		Obtaining environmental historical information by asking an adult asthma patient whether his or her symptoms improve when away from work and worsen during periods at work is important in detecting potential cases of occupational asthma.
