...hydrogen. Water is the only natural substance that found in liquid, solid and gas. The boiling point for water is 100°C, however the freezing point is 0°C. H2O is a necessity for all living things, every living thing on earth need water to survive and it helps human in certain ways. Example like digestion, respiration and etc. Human bodies are made up of 60-65% of water and so water plays an important role to us in our life. The aim of this report is investigate will 8 glasses of water a day gave a better life to people? This study draws on information gathered from various Malaysian and international articles, journals, and World Wide Web sites. Figure 1: Drinking water 2.0 Advantages of drinking water Water is a necessity for all living things in this world and human could only survive in three days without drinking water so it plays an important role throughout our life. Drinking more water not just makes us healthier but to make sure all our organs in our body work smoothly. 2.1 Excretion Water is the solution for maintaining a healthy lifestyle by drinking generous amounts of water every day is essential for good health because it helps our body to cleanse our body toxins out through kidney (Batmanghelidj, n.d). Kidney and livers play an important role in excretion and water helps kidney and livers to function properly by carry away toxins from the human body. 2.2 Perspiration When we having a cold or fever we need more water to standardize our body temperature and water help...

...are aware that our careless use of hazardous chemicals and fossil fuels may leave the planet uninhabitable in the future, most over look the fact that they also cause real damage to our bodies at this moment. Such pollutants cause damage to our respiratory system, leading to the fluctuation of the life span of an individual depending on a number of conditions. Amongst these conditions are the individuals specific geographic location, age, and life style. In this essay I will try to explain what pollutants are and how they affect our bodies. What are the pollutants? And how do they affect our bodies? In order to understand how air pollution affects our body, you must understand exactly what this pollution is. The pollutants that harm our respiratory system are known as particulates. Particulates are the small solid particles that you can see through a ray of sunlight. They are products of incomplete combustion in engines example: automobile engines, road dust, and wood smoke. Billions of tons of coal and oil are consumed around the world every year. When these fuels burn they produce smoke and other by-products into the atmosphere. Although wind and rain occasionally wash away the smoke given off by power plants and automobiles, much still remains. Particulate matter (soot, ash, and other solids), usually consist of unburned hydrocarbons, carbon monoxide, sulphur dioxide, various nitrogen, oxides, ozone, and lead. The process by which these pollutants harm our bodies begins...

...Petrochemicals and their byproducts, such as dioxin, are known to cause an array of serious health problems, including cancers and endocrine disruption. Of the more than 75,000 chemicals registered with the Environmental Protection Agency, only a fraction have gone through complete testing to find out whether they might cause problems for human health. Many that are produced in enormous quantities have never been tested at all. Usually, it takes dramatic episodes of workplace injuries or wildlife poisonings, combined with rigorous scientific proof of harm and public outcry, before the government will act to restrict or ban any chemical. And that is no accident. The current regulatory system allows synthetic chemicals into our lives unless proven beyond doubt to be dangerous. Terms Dioxins are not intentionally manufactured. They are unintentionally formed as byproducts of chemical processes involving chlorine, such as the manufacture of pesticides and the bleaching of paper. The manufacture and incineration of plastics such as polyvinyl chloride (PVC, commonly used in consumer product packaging and medical devices) is another major source of dioxin. Two of the most serious health effects of dioxin exposure are cancer and endocrine disruption. The endocrine system is a complex network of glands and hormones that regulate many of the body's functions including growth, development, and maturation, and the way various organs operate. The endocrine glands –- including the pituitary...

...My Environmental Worldview. Now at the turn of the two centuries the mankind comes to grips with the sharpest global problems of the modern world menacing to the existence of a civilization and even of the life on our planet. Inability to foresee and to prevent negative consequences of scientific and technical revolution threatens to cause to fall the mankind into thermonuclear, ecological or a social disaster. In many cities and rural areas the present state of the environment can be called as an ecological disaster. And the number of these cities and rural areas is still being increased. We are almost on a threshold of the close global catastrophe. If the mankind doesn't give a priority to the problems of ecology and multiply efforts on preservation and restoration of the natural environment in its activity, probably it will soon collide with irreversible processes not only in the nature, but also in the evolution of the human being as a part of the nature. Everyone should know the problems facing to the mankind: Human population growth, waste management, sustainable development, energy, depleting forests, mineral, water, soil resources etc. Exactly the Earth topsoil represents the major component of the Earth biosphere. The significant value of the soil consists in accumulation of organic matter, various chemical elements, and also energy. The topsoil performs functions of a biological absorber, the destroyer and neutralizer...

Improved education and awareness of the disease is essential in preventing it. NGOs can provide training in these areas. Another way of prevention is improved living conditions. Poor sanitation, overcrowding and malnutrition all contribute to the spread of disease. Sponsored community based programs can prevent disease infection. Housing projects can assist overpopulation. Disease prevention also requires health care programs. International efforts to fight diseases benefit both the United States and the global community. Health emergencies throughout the world will continue, and we must prepare....

...Fracking and its major implications it has on the earth In today’s day and age, societies are a lot more aware of the environment and furthermore, concerned for the Earths sustainability. Although this is the case for most, Multinational Enterprises (MNEs) often target developing countries that are rich in resources and therefore take them for all they’ve got. One such example is fracking the earth, in order to extract natural gases that could potentially benefit corporations and contribute to their bottom line dramatically. Although this has it’s positives, the implications of fracking could have incredibly serious repercussions, particularly the preservation of the earth and it’s current resources. “Fracking” is the process in which one would drill thousands of meters below the earth’s surface and inject fluid that is then pumped into the shale at an incredibly high pressure, which then shatters the rocks in order to release shale gas. This particular natural gas is trapped within sedimentary shale rock formations and is found richly in many areas of the world. Fracking breaks most of the regulations in the sustainable environments handbook, and as you can imagine, this causes a massive up brawl in the societies that are pro-environment and sustainability. Although this point of view is prominent and relevant, the opposing side has an equally compelling argument. Global thoughts on the idea of fracking Globally, the topic is thought to be both “one of the best...

Background of the Study Smoking remains a pediatric epidemic with so many adolescents stubbornly refusing to quit. This epidemic is predicted to kill 250 million children and adolescents who are alive today, a third of whom live in developing countries.Tobacco is addictive, carcinogenic and deadly. Analysis has shown that a tobacco leaf contains about 1,000 chemical substances. The smoke carries more than 4,000 chemically different compounds, mostly harmful to man. Tobacco is known or probable cause of some 25 different diseases for lung cancer, bronchitis and Emphysema it is a major cause. According to World Health Organization (WHO) estimated that there are 1.1 billion smokers in the world at the beginning of this decade and it is one-third of world’s adult population. Four million people died yearly from tobacco related diseases throughout the world. WHO estimates that the figure will rise to 10million by the year 2030 that’s one death every three seconds. Help is available through treatment methods that involve a combination of behavioral treatment and pharmacotherapy, telephone helplines, national and international tobacco-free days and stop smooking seminars but both smokers and healthcare professionals...

Health and well-being are not only affected by an individual’s lifestyle choices (e.g. smoking, eating unhealthy ‘fatty food), but also by societal and environmental issues (e.g. living near a motorway – high pollution levels) Government policies and legislation have an imperative part to play in the promotion of good health, as the introduction on screening programmes (e.g. cervical smear test, antenatal screening etc.); which prevent ill health, has been an incredible and useful tool. Health promoters also have a significant role to play in helping individual’s using services to make the right decision about their health. As their choice of presentation approach can make or damage a health promotion campaign. Further, health promoters need to take into account the presentation methods, and to ensure that they have been chosen well to confirm that the message is successfully put over to the individual to whom it is directed. What is ‘health’? The Worlds Health Organisation (WHO) defines health as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. However, others may simply define health as the absence of illness...

...beliefs and religions. People believe and used to assumed masturbation as unhealthy behavior and might harm the person that act it out. Indeed, the assumption was totally wrong. The impact of masturbation can only be identified depending on various factors that effecting and affecting. Cited in the classical article on the theology of masturbation, Father Jos. Farraher, S.J., describes masturbation as “the stimulation of the external sexual organs to a point of climax or orgasm by oneself, by movements of the hand or other physical contacts or by sexually stimulating pictures or imaginations (psychic masturbation) or by a combination of physical and psychical stimulation."2 In a broader sense this includes mutual masturbation in which persons touch one another's genitalia”. (John F. Harvey) It means that masturbation is sex pleasure for one person only. It may or may not include the stroking of genitals and also orgasm. An individual could also masturbate with partners or so-called as ‘mutual masturbation’. Other terms to describe masturbation are ‘onanism’ and ‘self- pleasure’. Also, referring to Better Health Channel, “masturbation means touching and rubbing your penis or clitoris and breasts for sexual pleasure. It’s a normal and healthy way for people to explore their own bodies. It’s also a form of safer sex that lets people find out what feels good, where and how they like to be touched and how to have an orgasm”. People used to be attached with stigma when it’s come...

...Molecules, Biodiversity, Food and Health Biological Molecules Biological Molecules (a) describe how hydrogen bonding occurs between water molecules, and relate this, and other properties of water, to the roles of water in living organisms; Water is a polar molecule. This is because the oxygen atom pulls the shared electrons towards it, meaning that water is slightly negatively charged at the oxygen and positively charged at the hydrogen ends, so they can form hydrogen bonds with each other. This are continuing breaking and reforming, so the molecules can move around. Property of water Solvent Importance Metabolic processes in all organisms rely on chemicals being able to react together in solution Examples 70-95% of cytoplasm is water. Dissolved chemicals take part in processes such as respiration and photosynthesis in living organisms Liquid The movement of materials around organisms, both in cells and on a large scale in multicellular organisms requires a liquid transport medium Water molecules stick to each other creating surface tension at the water surface. Cohesion also makes long, thin water columns very strong and difficult to break Blood in animals and the vascular tissue in plants use water as a liquid transport medium Cohesion Freezing Water freezes, forming ice on the surface. Water beneath the surface becomes insulated and less likely to freeze Thermal stability Large bodies of water have fairly...

Abrasive blasting; abrasive blasting operations can create high levels of dust and noise. Abrasive material and the surface being blasted may contain toxic materials (e.g., lead paint, silica) that are hazardous to workers. Silica sand (crystalline) can cause silicosis, lung cancer, and breathing problems in exposed workers. Coal slag and garnet sand may cause lung damage similar to silica sand (based on preliminary animal testing). Copper slag, nickel slag, and glass (crushed or beads) also have the potential to cause lung damage. Steel grit and shot have less potential to cause lung...

...Content Water they say is life, and indeed they were right. With about 70% of the earth’s cover being water; it undeniably becomes one of our greatest resources. Water resources are used in various ways including direct consumption, agricultural irrigation, fisheries, hydropower, industrial production, recreation, navigation, environmental protection, the disposal and treatment of sewage, and industrial effluents. Water has sources and supplies, economic, social, and political characteristics which make it a unique and challenging natural resource to manage. Water resources refer to the supply of groundwater and surface water in a given area. Water resources may also reference the current or potential value of the resource to the community and the environment. The maximum rate that water is potentially available for human use and management is often considered the best measure of the total water resources of a given region. With two thirds of the earth's surface covered by water and the human body consisting of 75 percent of it, it is evidently clear that water is one of the prime elements responsible for life on earth. Water circulates through the land just as it does through the human body, transporting, dissolving, replenishing nutrients and organic matter, while carrying away waste material. Further in the body, it regulates the activities of fluids, tissues, cells, lymph, blood and glandular secretions. An average adult body contains 42 litres of water and with just a small...
