Harmful Environmental Toxins and Beneficial Enzymes

Environmental toxins cause innumerable health hazards to humans as well as to our ecology. Enzymes on the other hand, are beneficial to health. How can you safe guard your body from the harm of environmental toxins? How do enzymes help to make your body strong? Read on to know more about the harmful toxins and healthy enzymes. Change your life style to make it healthier.

Environmental toxins have risen to a level which human body is not able to handle anymore! What is the plight of humanity if the issue is not addressed urgently and measures taken to control it? The World Health Organization is constantly and continually pointing fingers at environmental toxins as the prime reason for most of the diseases. In these circumstances what can we as humans do to make our body healthier?

Environmental toxins in recent times are chemicals, synthetic substances, different pollutants, pesticides etc. Human body stores these foreign elements beside the elimination system, in order to protect our body. The toxins build up in the fat of our body, resulting in many diseases.

Researches are being conducted to find out the causes for environmental toxins and for its cures. Meanwhile, we can resort to beneficial measures to lower the burden of toxins on our body and to flush away toxins that are already in our body. Body cleansing methods can improve your health and help body to function at its best. Unfortunately even the food stuffs we buy from market is low in nutrition as they are over cooked, over processed and over refined. The result is fatigue and weariness in us.

In order to enhance our energy level we take stimulants like soft drinks, coffee, and varieties of junk food. This results in the lack of nutritious and fiber rich food items in our body. Digestive system become unclean and will not work well. Colds, hay fever, headaches, allergies, dry skin etc become a day to day problem. Thus environmental toxins create unforeseen health problems to our body.

Contrary to environmental toxins, enzymes enrich our body significantly. Digestive enzymes and systemic enzymes are highly beneficial to our body. Digestive enzymes assist in lessening inflammation, reduce fibrin, and clear the blood of alien contaminants. The digestive enzymes strengthen the immune scheme and enhance its energy level.

Bromelain is a digestive enzyme capable of lessening inflammations. It is used in the treatment of hemorrhoids. Bromelain stimulates the break down of the substance fibrin. Fibrin is effective in treating internal wounds, damaged tissues and open wounds. However, excess fibrin build up is not healthy.

In order to control and manage too much fibrin actions, systemic enzymes should be administered. Systemic enzymes work in our body to eliminate harmful particles from our blood. Fresh pineapple is a good source of this enzyme. Digestive enzymes are popular as they break down food items and improve the digestion process. Systemic enzymes on the other hand are found inside our body. They can be found inside your tissues, inner limbs, cellular material etc. They aid in every type of chemical reactions of your body.

Environmental Causes Of Obesity

Just because you have obesity in your genes doesn't mean that there isn't anything that you can do about it. Environment can also play a big part in whether or not you are obese. Eating habits and lack of physical activity have a large role in obesity too. Generally Americans go with taste and convenience more than they do with nutrition. High-fat foods are usually the most convenient such as fast food.

In society today people are more rushed than ever. We are always in a hurry to get some where or do to something. This often leaves us with the feeling that we do not have time to eat a healthy meal, or to take the time to eat before said healthy meal. For this reason, we feel that we are forced to settle for what is fast, easy and convenient. Not only is fast food packing on unwanted pounds, it's causing tremendous health risks in the process.

Besides the fast food eating way of life, we are more sedentary than ever. The age of sedentary is getting lower and lower with each passing year. Our children are watching more television, playing more video games, and spending more time on the computer than we used to as children. Now adults, we as children, spent the majority of our time outside playing or being involved in other physical activities. While children today are involved in sports, or dance, most overweight children are not. They pick up this conditioning from their parents who are teaching them these things. Because parents today are so rushed and so busy, they take the valued spare time they have to "veg out" in front of the television or computer. Children see these things and learn these things, therefore taking on the unhealthy lifestyle of the parents. We as adults and parents need to learn to be more active in our lives, and learn healthy eating habits. Not only for our health and well being, but to be role models for today's children, that as adults, they do not end up overweight, and unhealthy.

An environment that promotes healthy weight is one that encourages eating nutritious foods in reasonable portions and regular physical activity. A healthy environment is important for all individuals to prevent and treat obesity and maintain weight loss.

Healthy environments can be created at home, school, work and beyond. Identifying and consciously avoiding high-risk situations in the environment can help in weight control efforts.

Chemical Fertilizers, Health, Environment and Bio-Fertilizers

The over-use of chemical fertilizers and pesticides in tandem with the Green Revolution of nineteen sixties and seventies (also known as the new seed-fertilizer-water technology) in the Indian context following two decades of their widespread application in the West, has hardened the soil, decreased its fertility, polluted air and water, and brought hazards to our health and environment. Ironically, despite the disastrous consequences of the Green Revolution in the northern parts of the country in recent years, the government seems to be in mood to spread the aftermath of this chemical-seed-fertilizer technology to other parts of the country. However, the hazards of chemical fertilizers on health and environment have been well established by studies carried out from time to time and they pose serious challenges to sustainable development. In this perspective moving towards bio-fertilizers and organic farming from a system of farming requiring high doses of chemical fertilizers and pesticides seems to be a viable alternative as the latter is observed to be friendly to health and environment.

Chemical Fertilizers and Environment

Chemical or synthetic fertilizers are basically salts by definition, and therefore, are expected to be harmful to agriculture in the long run. Yet they were promoted by their manufacturers under the misgiving that they would replenish the nutrients in the soil. Contrary to this, studies carried out from time to time have established that synthetic fertilizers tend to replenish only nitrogen, potassium, and phosphorous, while depleting other nutrients and minerals that are naturally found in fertile soil. Decrease in soil fertility also corroborated with continual use of chemical fertilizers and pesticides in the field as revealed in these studies.

Excessive use of phosphatic fertilizers cause hardening of the soil as phosphorous does not dissolve in water, while alkaline fertilizers like sodium-nitrate, basic slag develops alkalinity in soil reducing its fertility. Increasing use of chemical fertilizers also causes imbalance in quantity of specific nutrients in the soil adversely affecting, in turn, soil fertility and vegetation.

Soil fertility is also reduced due to pesticides applied to wipe out unwanted herbs in the field, insecticides meant to kill pests, and chemicals that have bio-cidal activity affecting rodents etc. Pesticides cause land degradation in various ways. They kill some useful species like the earth worms and micro-organisms that maintain the natural fertility of the soil by their activities. The bacteria or micro-organisms in the soil would normally break down organic matter into plant nutrients, and help convert nitrogen from the air into a plant-usable form. There are other useful soil bacteria such as "disease organisms" which keep cutworms, chinch bugs, grubs, and other parasites in check. Decline in the organic matter of the soil also results in hardening of the soil which, besides affecting vegetation also decreases infiltration and water retention capacity.

Besides, application of chemical fertilizers and pesticides causes contamination of the aqua system both directly and indirectly. For instance, nitrogen is toxic to fish and invertebrates. It is also toxic to humans. People who depend on rural wells for potable water have higher risk of exposure to conditions like Methemoglobinemia, and aka Blue Baby Syndrome which damages blood cells and is traced to high levels of nitrate concentration as ground water is contaminated. The herbicide atrazine, one of the most commonly used pesticides, is known to be a common water contaminant. Pesticides developed in recent years are found to be more toxic to water dwelling insects, planktons, crustaceans and fish. Even a low level of the herbicide atrazine, through contamination of streams, ponds and estuaries can be harmful to the whole aqua system. It may inhibit the growth of algae and plankton affecting the diet and reproduction of fish or other water bodies.

It has been observed that, chemical pesticides no more killed the target pests, for the latter had developed resistance absorbing the residue of such pesticides while they have hit the non-target pests, birds and micro-organisms beneficial to agriculture and environment. There are pesticides like organochlorine that are, though breakable, relatively faster than DDT, hit the non-target organisms. They enter the food chain of human-beings and remain accumulated in species like the eagle, falcon and kites. The recent decline in the eagle population is the cause of it. There are cases of decline in kite and vulture population in India due to use of pesticide of an US multinational corporation. It was banned only recently following protest by ecologists.

Again, use of pesticides not only pollutes the ecosystem contaminating the soil and acqua system, but also pollutes the air. For, even a careful spray of pesticides can make it mix in the air as vapour. As a result, there are chances of poisoning of bees and other pollinators. Thus, apart from posing a threat to biodiversity affecting flora and fauna, chemical fertilizers and pesticides destroy the environment through air, water and soil pollution.

Chemical Fertilizers, Bio-fertilizers and Our Health

Pesticides and overuse of chemical fertilizers also affect our health by retaining the residue by food chain. There are evidences of residues of pesticide in vegetables causing chronic health conditions in human-beings such as cancer and other systematic dysfunctions. Residues in food and water extend the hazards to a much wider population than that affecting the farmers alone.

A twelve-year study by researchers comparing organically grown and chemically grown foods found that synthetic nitrogen fertilizer leaves toxic nitrates in vegetables at least 16 times higher than that found in vegetables grown organically. Nitrates and residues of pesticides have oncogenic or cancer producing elements. The element omega-3 found in vegetables protects us from heart disease, cancer and Alzeimer's disease. But it is decreasing day by day in foods chemically grown. As is obvious, these diseases were not very common before the World War II when chemical fertilizers were not used.

Scientists have found that minerals containing in the food are crucial to our health. They keep us disease free. Mere vitamins and calories are not sufficient for our survival. But it has been established by studies that chemical fertilizers and pesticides destroy the essential minerals in crops and vegetables. In comparison to vegetables grown under organic system of cultivation these minerals are found much less in quantity in chemically grown vegetables. So it is argued that the foods coming from modern agricultural methods would only fill your stomach but you remain deficient in nutrition.

Again, studies carried out by researchers in the US and UK over last seventy years has come to the conclusion that organic fruits and vegetables contained 27 per cent more vitamin C than those chemically grown. Besides, they invariably contained more minerals and much less toxic nitrates.

Bio-Fertilizers and Bio-pesticides as Alternatives

Unlike the synthetic fertilizers, bio-fertilizers would have no obnoxious problems on our health and ecosystem. Bio-fertilizers include excreta of animals such as cow-dung, vermin-compost, dhanicha (green manure), organic wastes, crop residues, manure etc having biological or organic origin. Use of bio-fertilizers brings back the natural fertility of the soil without causing harm to earth-worms and micro-organisms. Besides, these fertilizers do not leave toxic residues in the food. Far from it, they would retain the natural minerals and the plant absorbs from the soil.

Bio-fertilizers like vermin-compost will increase soil fertility and prevent hardening of the soil. The vermin and living micro-organisms in the soil would also break the naturally available nitrogen from the air for plant use. Again, it will help allowing infiltration of rain water rather than causing water-logging. The use of bio-fertilizers will have little detrimental effect on ground water as there would be little nitrogen leaching into the earth contaminating the water.

Again, the use of animal and plant wastes in the field as manures will clean the environment. The organic wastes piled up everywhere can be used as compost reducing the environmental pollution. Besides, the deposits from ponds and aquatic systems can be used as bio-fertilizers and pesticides. This will clean the aquatic system while increasing productivity in the field.

As against the poisonous chemical pesticides bio-pesticides prepared from natural biological resources like plants and standardized microbes have no harmful effects. Local bio-pesticides like neem leaf and oil, karanj (derris indica) extracts and oil, cow urine can be used as insecticide and fungicide. Unlike the chemical pesticides they do not hit the non-target pests nor do they pollute the environment.

Preparations of neem include neem cakes, neem kernel, neem oil etc. Neem leaves and oil have been used by farmers in the Indian subcontinent since time immemorial as effective pesticide and preservative as well. Scientists in India, US and Europe have discovered many properties of neem as an obnoxious pest controller. Studies have shown that instead of killing pests at one go neem serves as a pest repellant and ovipositional deterrent, that is, pests do not spread eggs on plants applied with neem extracts.

Karanj oil and preparations made from it (now available with firms manufacturing them) serve as effective insecticide and miticide. All kinds of mites causing harm to plants like the red spider mites, scarlet mites, yellow mites etc are effectively controlled by preparations made from karanj.

Conclusion

The development of hybrid seeds of cereals, pulses and other crops though raised the productivity and supported the growing population of the country from starvation, since the sixties, it required greater use of chemical fertilizers, some of the compounds imported from developed countries. After two decades of the Green Revolution it was found that the soil was losing its fertility demanding more and more of chemical fertilizers for the high yielding varieties (HYV) of seeds to raise productivity, while pesticides were to be used in greater doses as pests developed greater resistance. Today the situation is so acute that productivity cannot be increased without surpassing the dangerous level of fertilizer use affecting health and environment, especially in regions like Haryana and Punjab where the per capita consumption of chemical fertilizers is very high. In view of the above hazardous effects of synthetic or chemical fertilizers and pesticides, the question arises, should we continue the use of HYV seed-chemical fertilizers technology? If not, what are the alternatives? In the present context, a system of organic farming using indigenous rather than HYV seeds with bio-fertilizers and local pesticides seems to be the only solution. It is time that both the Union and State Governments should arise from their slumber and promote and propagate the system of organic farming dismantelling the use of chemical fertilizers and pesticides.

Relationship Between Health and Environment

We are living in a world of contrasts. Scientific and technological progress has brought advanced health care system; many diseases today that were fatal in the past, if not eradicated, are brought under control. As a contrast, people living in developed countries are suffering from cardiovascular diseases and cancer associated with inappropriate diet and stressful life.

Industrial revolution brought social and technological development, but also introduced pollution on large-scale. With modern industry things have just got worse. When the extent of industry was limited, contamination area was reduced to immediate vicinity affecting health and safety of those workers directly involved in production. In a modern global society we live in today this problem has become, well, "global". The toxic that is most common in our environment is lead; it is used in vaccines, pesticides, antiperspirants, building materials, gas and even found in drinking water. If we think about global population growth and its growing needs and industry relying on components that are toxic, we can assume that industrial development has a devastating impact on environment and public health.

In the past, diseases were attributed to meteorological events such as changes in the seasons, storms and eclipses. Some societies linked disease to corrupt or polluted air from corpses, swamps and other sources. In prehistoric times people believed that evil spirits or God caused people to become ill. By the 16th and 17th centuries connection between health and environment had become commonly recognized. Fresh air and elimination of bad smells were considered important, and a healthy environment was thought to produce healthy food and drink. Earth was respected as a living, breathing body that needed to be nurtured and protected.

The industrial revolution drastically changed the relationship between economic activity and environment. By 19th century, industrial pollution had been identified as a serious problem. This was mostly due to energy requirements of iron industry and led to local and ultimately, more widespread pollution. Although it was considered a serious problem, it was not given high priority. Social problems, infectious diseases and unsafe water supplies were the main health concerns at that time.

Until the late 19th century, the causes of fever, pestilence and plague were still unknown. Odors and emanations were still considered responsible, just as in ancient Greece. Gradually, other theories were introduced, like "germ theory", which enabled Louis Pasteur and Robert Koch to prove the existence of bacteria and how they caused diseases. By the end of 19th century, the transmission of diseases via insects was also identified. This meant that new ways could be found to fight disease and resolve health problems.

In the late 19th century, there occurred a growing awareness of the importance of environment. During the 1860's both USA and Great Britain passed laws aimed at protecting the environment. Early environmental movements tended to be led by professionals such as foresters, who were interested in preservation and management of land and resources. In 1892, the Sierra Club, USA's oldest and largest environmental organization was founded with John Muir as president. Their first campaign was an effort to defeat a proposed reduction in the boundaries of Yosemite National Park under slogan that: "Everybody needs beauty as well as bread, places to play in and pray in, where nature may heal and give strength to body and soul alike" (John Muir 1912).

During the 20th century, a growth in demand increased the volume of hazardous materials and further increased pollution. This trend caused a massive public revolt in many parts of the world. In 1962, Rachel Carson published her book "The Silent Spring", where she detailed some of the dangers that pesticides could have for the environment and human health, and raised public awareness of alternative ways of perceiving human health in relation to environment. During 60's and 70's there was a major expansion of environmental organizations such as Greenpeace lobbying for clean water, air and preserving of wilderness.

However, global warming was not adequately discussed. It appears that there was not enough political will to address global warming issues. Authors Michael Shellenberger and Ted Nordhaus in their book "The Death of Environmentalism" (2004) debate about environmental movements not being efficient enough to motivate a national debate; e.g. using low emission vehicles or energy-efficient light-bulbs is neither inspiring nor comprehensive enough and are unlikely to be successful. They think that the answer to the problem is selling the solution rather than focusing on the problem itself. The solution may be support for an economy based on new energies, not fossil fuels. It would reduce dependence on oil, air pollution and bring more jobs. Investment in this strategy would allow a better use of accessible resources than what the conventional environmentalists suggest.

My name is Julija Trkulja or Benedict (that's my author name I use on my Website). I'm from Belgrade, Serbia. I have just recently created a web site: http://earthgonegreen.com where I write about environmental issues and try to bring this current problem called global warming which we are all experiencing closer to a broader audience, because I think it is very important to become aware of it and to make whatever action we can, even if it is just writing about it and promoting it. I have included health, food and farming on my blog as a part of this holistic approach to what I like to call "sustainable lifestyle". Join me!

Walking and the Environment

"Today I have grown taller walking with the trees." Karle Wilson Baker

We all know that exercise is good for you. And walking is probably the easiest form to get into.

But did you know that walking plays a part in helping improve your environment?

Walking improves our quality of life because it helps to protect the living environment and natural resources. It can also be built into transportation systems.

Added health and environmental benefits come from the fact that walking is a pollution free activity. It's also a quiet pastime. So we benefit from cleaner air and there's a reduction in traffic noise too.

"Walking is highly efficient in its use of urban space and energy, it rarely causes injury and it gives streets vitality and personal security. Many car trips are quite short, less than 2 km, indicating that walking could be a feasible alternative and contribute to reducing the pollution from a cold-start vehicle travelling only a short distance."
C. Mason, Transport and health: en route to a healthier Australia? Medical Journal of Australia 2000

In North America and in Europe, there are active groups who canvass for better walking facilities in the urban communities. They argue that walking opens up communities and adds to the quality of life for all.

In 1996, Dan Burden formed Walkables Communities (http://www.walkable.org) in Florida. Walkable Communities purpose is,

"... helping whole communities, whether they are large cities or small towns, or parts of communities, i.e. neighbourhoods, business districts, parks, school districts, subdivisions, specific roadway corridors, etc., become more walkable and pedestrian friendly."

In the UK, Living Streets (http://www.livingstreets.org.uk) is a similar organisation who state their aim as being,

"... the champions of streets and public spaces for people on foot. We work on practical projects to create safe, vibrant and healthy streets for all.
Local streets are a service that we all use. But for decades, traffic priorities have been allowed to overwhelm them, and they have been left dirty and unsafe. Vibrant streets help to revitalise neighbourhoods and reconnect people."

These organisations and their campaigns to free our communities from excess traffic appear to make sense. It is true that motor vehicles create a large amount of the pollution we find in the air.

The pollution created by vehicles can contribute to ill health. Illnesses such as asthma, lung cancer, increased stress and disturbed sleep have been found to be due to increased air pollution.

Walking on the other hand improves health, because every walk reduces air pollution.

So, do you want to take a walk today? Every step you take plays a part in improving your local community.
