Survival of the Sickest: A Medical Maverick Discovers Why We Need Disease Dr. Sharon Moalem See book keywords and concepts

The savanna theory holds that our apelike ancestors abandoned the dark African forests and moved into the great grassy plains, perhaps because of climate changes that led to massive environmental change. In the forest, food was plentiful—fruits, nuts, and leaves could be found in abundance. But out in the savanna, life was tougher, so the theory goes, and our ancestors had to find new ways to get food. Males began to hunt bravely for meat among the herds of grazing animals.

Safe Trip to Eden: Ten Steps to Save Planet Earth from the Global Warming Meltdown David Steinman See book keywords and concepts

The international team blamed "heat-trapping gases from tailpipes and smokestacks around the world [that] are contributing to profound environmental change." The only way we can be sure we're doing what is right is to see tangible results. If we start seeing levels of fossil fuel residues declining in polar bears, and healthy populations of wild salmon and amphibians, we will know we are hedging our bets against global warming. But that's going to require some major changes in our consciousness. Part of that change has to involve our being kind to animals, even farm animals.

Dirt: The Erosion of Civilizations David R. Montgomery See book keywords and concepts

In contrast, the cultural evolution hypothesis holds that regional environmental change was unimportant in the gradual adoption of agriculture through an inevitable progression of social development. Unfortunately, neither hypothesis provides satisfying answers for why agriculture arose when and where it did. A fundamental problem with the oasis theory is that the wild ancestors of our modern grains came to the Middle East from northern Africa at the end of the last glaciation.

Plant Spirit Healing: A Guide to Working with Plant Consciousness Pam Montgomery See book keywords and concepts

The Gaia theory also "sees the earth as a responsive supra-organism that will tend to resist adverse environmental change and maintain 'homeostasis.' But if stressed beyond the limits of whatever happens to be the current regulatory apparatus, it will jump to a new stable environment where many of the current species will be eliminated." This illuminates the fact that the earth is a creator of its own existence and that environmental homeostasis or balance is necessary for life as we know it to be maintained. Spirit is defined in Webster's dictionary as "the vital principle held to give life.

Dirt: The Erosion of Civilizations David R. Montgomery See book keywords and concepts

As much as climate change, the demand for food will be a major driver of global environmental change throughout the coming decades. Over the past century, the effects of long-term soil erosion were masked by bringing new land under cultivation and developing fertilizers, pesticides, and crop varieties that compensate for declining soil productivity. However, the greatest benefits of such technological advances accrue in applications to deep, organic-rich topsoil.

Food Fight Kelly Brownell and Katherine Battle Horgen See book keywords and concepts

Nutrition education in the absence of environmental change is not likely to have significant effects (and sends mixed messages), and environmental change without nutrition education is likely to miss opportunities to teach children lessons they can use outside school. Teaching children healthy eating habits, coupled with changing the environment, is likely to have the greatest impact on overall lifestyle. Both education and environmental change are important. The School Food Triad: Three Barriers to a Healthy Food Environment Three barriers to healthy eating are fundamental to schools.

The Science of Flavonoids Erich Grotewold See book keywords and concepts

In this context, if an environmental change caused the production of one or a subset of these compounds to become advantageous, natural selection would act to enhance its production. At first, the mechanism of enhancement may have been quite crude (e.g., up-regulating a key enzyme of primary metabolism) and probably would have had deleterious pleiotropic effects. If, however, the advantages of increasing the production of flavonoids were large enough, this would evolve despite the pleiotropic effects.

Water: For Health, for Healing, for Life: You're Not Sick, You're Thirsty! F. Batmanghelidj See book keywords and concepts

When this irritation occurs, the brain is alerted about the chemical environmental change, which is translated and manifested as pain to the conscious mind. In other words, it is the acidity in the interior of the body that causes pain. Mechanism of Pain Production Alkaline Acidic (Dark urine) Figure 8.1: Nerve endings register the chemical environmental change with the brain. The brain translates the information for the conscious mind in the form of pain.

Water: For Health, for Healing, for Life: You're Not Sick, You're Thirsty! F. Batmanghelidj See book keywords and concepts

Nerve endings register the chemical environmental change with the brain. The brain translates the information for the conscious mind in the form of pain. Normally, when blood that contains an ample amount of water circulates around the cells of the body, some of the water goes into the cells and brings out hydrogen molecules. Water washes the acidity out of the cell and makes the cell interior alkaline—an absolutely essential and normal state. For optimum health, the body should maintain an alkaline state— pH 7.4 is the desired level. Why 7.4, and what is pH?

The Missing Gene: Psychiatry, Heredity, and the Fruitless Search for Genes Jay Joseph See book keywords and concepts

Approaching this question from a different angle, although the human trait of having two arms is inherited, the heritability of humans having two arms is zero. The reason is that the heritability statistic describes variation in a population attributable to genes. Because virtually everyone is born with two arms, and because people with one arm become that way because of an environmental occurrence, 100% of the "armedness" variation in a population is caused by the environment, and 0% of the variation is caused by genes.

Food Fight Kelly Brownell and Katherine Battle Horgen See book keywords and concepts

Both education and environmental change are important. The School Food Triad: Three Barriers to a Healthy Food Environment Three barriers to healthy eating are fundamental to schools. These must be considered if schools are to become healthy places to eat. Schools Do Not Consider Healthy Eating Relevant to Their Mission What children eat has not typically been viewed as important to a school's educational mission. Providing food is often seen as a necessary service, much as custodial service might be, and is expected to generate a profit or at least break even.

Finally, in Section V, "Prevention and Environmental Action," we examine ways in which to act on your knowledge of environmental health, we outline a preventive health plan and examine the political and social avenues for environmental change. We hope that this book will provide a valuable source of information about environmental health, but we also hope that it will help you to feel confident, rather than terrified, about the prospects of living in today's world.

Helpful Hormones Melatonin—This "miracle" hormone produced in the pineal gland ensures that the levels of other vital hormones stay within a normal range in response to environmental change, lor instance, when we arc exposed to prolonged stress, our adrenal glands produce stress hormones called corticosteroids. Exposure over time to high levels of corticosteroids can cause damage to many of our organs and has been linked to Alzheimer's. Melatonin may also help Alzheimer's patients to recover their normal sleep patterns—a boon to caregivers and patients alike.

A New Science of Life Rupert Sheldrake See book keywords and concepts

The divergence of chreodes If a mutation or environmental change perturbs a normal pathway of morphogenesis at a relatively early stage, the system may be able to regulate and go on to produce a normal final form in spite of this disturbance. If this process is repeated generation after generation, the chreodic diversion will be stabilized by morphic resonance; consequently a whole race or variety of a species will come to follow an abnormal pathway of morphogenesis while still ending up with the usual adult form.

Nontoxic, Natural and Earthwise Debra Lynn Dadd See book keywords and concepts

Global environmental change ... is more deeply threatening than most people think," stated one expert. "And it is coming at us much faster than most people think . . . Advocates of delay are underrating the evidence of already existing harm." Thomas Lovejoy, assistant secretary for external affairs of the Smithsonian Institution, stated in 1988, "I am utterly convinced that most of the great environmental struggles will be either won or lost in the 1990s. And by the next century it will be too late." Clearly, there is a genuine need to act now, but we need to know what to do.

Instead, we would preferentially, and wherever possible, begin therapy with acupuncture and herbs, as well as family discussions, self-awareness, and relaxation techniques, breathing exercises, dietary and environmental change, and yoga. This new medicine of self-care and nontoxic intervention is already being practiced by many hundreds, perhaps several thousands of physicians. Some, like me, work individually, using a number of modalities themselves and, when appropriate, referring to conventional and nonconventional practitioners— Jane's oncologist, David's yoga teacher.

Life Without Bread Christian B. Allan and Wolfgang Lutz See book keywords and concepts

Humans are constandy in the process of adaptation, but today we can all see what is actually occurring in this interim period when a significant environmental change is taking place, but physiology is not able to keep up with the change. Given the choice, do you want to be part of this experiment? FROM CHIMPANZEES TO HUMANS The fossil record is probably the purest form of evaluation into the ancestors of humans. Discoveries are being made constandy, and every five or ten years human genealogy is reassessed. What is known today is very exciting.

Power Healing: Use the New Integrated Medicine to Cure Yourself Leo Galland See book keywords and concepts

Different qualities of temperature and moisture attributed to each humor explained the effect of environmental change and unsound habits in causing disease. Although Greek physicians were able to distinguish among different types of sickness in vague and broad terms, they saw, in effect, only one universal disease—an imbalance of the humors—the effects of which varied among different individuals, depending upon the unique circumstances of each case.

The Complete Idiot's Guide to Lost Civilizations Donald Ryan See book keywords and concepts

We've already talked about how environmental change may have affected human cultures after the Ice Age and about the situation in Egypt, where the hippos depicted on tomb walls no longer frolic in the papyrus swamps that likewise no longer exist there. Elsewhere in Africa, there's ample evidence of different environments long ago. In North Africa in particular, art in the form of drawings and paintings on rock show a different land: a tropical land where giraffes and other beasts of the savanna roamed in an area that is now a hot, rugged desert. An assortment of images from Tassili rock art.

The Omega-3 Connection: The Groundbreaking Anti-depression Diet and Brain Program Andrew L. Stoll See book keywords and concepts

These treatments are most effective when combined with psychotherapy and with attention paid to social and environmental change. The latest research suggests that supplements of omega-3 fatty acids may also be effective at countering some aggressive behavior and helping us deal with stress. Although the implications are powerful, much more work must be done to prove that omega-3 fatty acid supplements can reduce a tendency to violence. We await the results of future studies in our nation's schools and prisons, and hope that at least part of the answer may be as simple as an omega-3 fatty acid.
