THE 4 QUALITIES OF GOOD WATER by Dr. Robert O. Young There are many measurements of water‚ but the most important for determining the best water to drink are‚ the pH‚ oxidative reduction potential—or energy potential/activity—molecular structure‚ and purity. Science has helped us to determine that the best measurements for our drinking water are the pH and purity‚ but little understood is the importance of the molecular structure of water. Assuming that most waters that humans are drinking

“Is Gender Biologically Determined?”- Drawing upon ethnographic examples from 2-3 societies. Gender being ‘biologically determined’ means that whether gender is inherited or passed down by genetics. If a person is a man or woman‚ (which is usually called ‘The Sex’)‚ that is biologically determined because they inherit the chromosomes to be born a man‚ or to be born as a woman. In the early 1970’s sex was described by “biology as: anatomy‚ hormones‚ and physiology” (West and Zimmerman 1987). Apart

Fracking is currently regulated by the EPA under the clean water act of 2005 (EPA.gov). However‚ this only partially governs the methods of injecting fluids and the retrieval of such fluids into the earth. It does not govern the types of chemicals that are being allowed to be used‚ or how much fresh water is wasted (millions of gallons per “Frack job”) and it does not carry stiff enough penalties for spills or irreversible damage to community’s water supplies. For those of you‚ who are unfamiliar with

Explain how human activity can affect water availability and quality. (10) Agriculture plays a significant role in the quality of water and three factors come into play when considering agricultural effects: pesticides‚ fertilizers and the waste produced by farm animals. When pesticides or fertilizers are applied to crops the excess materials will either run off the land‚ or seep into the groundwater‚ with an eventual ending in bodies of water such as lakes‚ ponds‚ or streams. The excess nutrients

Are we really free? What is real freedom? Are we free or we have only the illusion of freedom? We are unconsciously controlled by various systems and are slaves to the system! If you do not adapt and go with the systems you are not uitgespeog and forget. Political‚ economic and social systems control our lives on a daily basis! We are limited to things we might do and actually do‚ we can swing our arms but we can not fly? We have freedom of speech but we can not say what we want. Many times we

Introduction Water is known as a vital component to sustain life. When one is confronted with the fact that water is considered a renewable resource in the short term but only 3% is usable (N.Gray)‚ precautions must be taken to ensure the conservation of water. The agriculture industry consumes approximately 70% of the planet’s usable water globally. At large scale the water footprint arguably cannot be reduced‚ raising the question on whether our water is being used to its full potential. Water can be

Killing somebody is maybe not the best way to grow up but for Johnny‚ it showed him he wasn’t weak and going to let people walk all over him. I think for Johnny it was a life changing experience that‚ had he lived would have turned him into a strong‚ determined young man. The other day at Jay Mountain he told me that he was willing to turn himself in to allow Pony to be with his family. He wasn’t scared anymore of what might happen to him‚ he just wanted it to be over. When he saw the church burning

How water is purified in water treatment plants Pre-treatment 1. Pumping and containment – The majority of water must be pumped from its source or directed into pipes or holding tanks. To avoid adding contaminants to the water‚ this physical infrastructure must be made from appropriate materials and constructed so that accidental contamination does not occur. 2. Screening (see also screen filter) – The first step in purifying surface water is to remove large debris such as sticks‚ leaves
