The Advantages of the Hand-Dug Wells in Ghana Hand-dug wells are an alternative to collecting muddy, diseased water a long way away. Here are some advantages of having this kind of access to this type of water: o Less time is spent collecting water from far away so people have more time on their hands. Children can go to school and receive education which means they can eventually get better jobs which could in the long-term help Ghana to develop. Adults can have more time on their hands. This may enable them to get a job and earn more money for their family which could improve the quality of their life. They could spend more time preparing food which may give the family a more balanced diet enabling them to live a long and healthy life. Young children can be looked after and if they are ill they have time to nurse them back to health. Without the journey to fetch water people feel much less tired giving them more energy for other things. o If there is access to clean water and diseases are not likely to be spread around, people are more likely to apply for jobs in the village. There may be more teachers in a school, so pupils receive more attention when learning. If a villager begins to employ people from elsewhere, he will be able to do more work therefore may be able to expand his business and make more money. Also, employees can inform others about that particular village, giving good publicity which may invite more work. Tourism may also develop in the village as tourists know they can be offered water which does not carry a threat. o In the water previously used by the villagers were risks of water diseases such as typhoid and cholera. Bacteria caused diarrhoea and tiny eggs that grew into worms inside you caused bilharzias and other infections. Now, with the hand-dug well villagers can access clean, safe water which does not carry disease. Families also do not have to spend lots of money on medicines so they have more opportunities to
money left in the family and they are living a poor and unhappy life without enough money
o Has created more sanitary water but less is available. Goats have also destroyed the grass. And each cattle post now has a permanent population of houseflies.
The Economics of Natural and Human Resources in Agriculture are dependent on water, according to Underhill (2015). “Legionnaires is associated a high mortality rate. The authors collected
A Black Hole is defined as an object in space that is so compact, that has a gravitational pull so powerful, not even light can escape its pull. In most cases Black Holes are formed when a massive star (much larger than our own) undergoes a supernova explosion. When this happens, the star may collapse on its own gravitational pull, thus resulting in a an object with infinitely large density and zero volume. As a result, the escape velocity (the speed required to escape the gravitational pull) becomes even greater than the speed of light, and because nothing can travel faster than the speed of light, nothing can escape a black hole.
What is a black hole? A black hole is a great amount of matter packed into a very small area. Think of it this way: imagine our sun compacted into Austin, Texas. Phenomenal cosmic power in an itty-bitty living space.
... hole. The opening of a black hole is called the event horizon. And once something goes inside, it is trapped forever inside of it. Light, matter and other things cannot escape. The radius of each event horizon is called the Schwarzschild radius, named after Karl Schwarzschild the person who led to the theory of black holes A black hole is when there is a strong gravitational pull and there was a time delayed. The whole light not being able to escape thing seems pretty complicated. why? Because when you think about it, light not being able to escape the black hole doesn't seem too realistic. Black holes are created from an overdensity of a star collapsing in on itself. That overdensity is what creates the whole black hole part, the concept of the black hole sucking things in and possibly destroying them without a trace, that is the part that makes it seem weird.
The Theory of Relativity, proposed by the Jewish physicist Albert Einstein (1879-1955) in the early part of the 20th century, is one of the most significant scientific advances of our time. Although the concept of relativity was not introduced by Einstein, his major contribution was the recognition that the speed of light in a vacuum is constant and an absolute physical boundary for motion. This does not have a major impact on a person's day-to-day life since we travel at speeds much slower than light speed. For objects travelling near light speed, however, the theory of relativity states that objects will move slower and shorten in length from the point of view of an observer on Earth. Einstein also
A Black Hole is an object that is so dense not even light can escape its gravity.
A lack of sanitation was a big factor in the reasoning of why life expectancy
win-win-win situation and a balance in the use of water resources for environmental, public health, and commerce problems in order to ensure the safety of human beings and halt dramatic changes to aquatic species and their environments. Lodge develops his point with environmental and public health statistics as well as numerous references that show the relationship between the necessity of water resources to live and our environmental problems. Lodge discusses the world problems of water resources and the needed better management of them in order to spread awareness about the topic as it is an overlooked, global problem. Lodge's essay is written in BioScience which is read by the well educated, but his essay seems to be targeted at a wider audience considering the weight of the issue and the easy readability of the piece.
Black holes are incredible processes that happen in space that are capable of crushing anything unlucky enough cross paths with them. Black holes have caught the attention of millions of people around the world because of their incredible strength and the fact that so much is unknown about them. The theories of possible outcomes resulting in traveling into a black hole has been used in many science fiction stories, but what we think is science fiction could actually exist. With black holes being out of our reach, and even difficult for our greatest minds to understand, what happens within them may just stay science fiction. The more we learn about black holes the more questions we ask.
The actual living conditions of people directly correlate to the spread of infectious diseases and infestation of chronic illnesses that result in premature death. Crowding, such as in ghettos and low income projects, creates an unnecessary closeness of people in a community. Therefore we see an increase in the spread of infectious diseases because human to human contact is inevitable. For instance, in the US controlled Marshall Islands has a population of over 10,000 people living in an area smaller than Manhattan. Tuberculosis runs rampant there and is often times left unchecked due to the lack of personal space in conjunction with poor sanitary conditions. Poor sanitation in a region is an effect of lack of public interest in the community and subsequently aids in the demise of the health of the population.
Dark Energy is a theoretical repulsive force that counteracts gravity and causes the universe to expand at an accelerating rate. More is unknown than known about Dark Energy. There had been many theories about Dark Energy before HST, but no one had hard evidence. The HST provided evidence
Outer space according to Dictionary.com is defined as "the physical universe outside of the earths atmosphere". Over the entire existence of mankind we have always wondered what is out there. The moon is one object that many people have always fathomed about. The moon is fathomed about in 3 aspects. These aspects include facts including theories the formation of the moon, the great space race, and wether or not the first moon landing was a hoax.
