Water Pollution - my final project

Water Pollution

Definition:

The addition of pollutants/particles/substances, which leads to the contamination of water bodies and toxification, can be broadly defined as water pollution. This generally is a result of adding untreated industrial waste and sewage directly into the water bodies.

Premise:

Water is a scarce resource. With rising population, demand on water usage is rising exponentially. In this scenario we can ill-afford pollution of water bodies. Water pollution is one of the most threatening problems in the present world (Water Pollution, 2009)

Nowadays, when water scarcity is widespread, water pollution is a big problem. To handle water scarcity full measures should be taken to deal with water pollution. Proper treatment of sewage and removal of chemicals and other harmful pathogens from industrial waste would be the basic measure for handling water pollution. This would help a lot in handling water scarcity ultimately resulting in the measures tacking for water pollution.

But if the different measures for stopping water pollution are not taken with immediate action then it may lead to water turning into the most precious but scarce natural resource in the world. (NRDC, 2013)

Reasons for Water pollution:

If we refer to UN Water for Life we can see there is a self-explanatory presentation which says that today in the present situation all over the 193 countries of the world, were 6,984,895,594 people suffer scarcity of water and those are all polluted as well. By the year 2050 almost 1.8 billion population will live in regions or countries with absolute water shortage and polluted water and 2/3 of the world’s population may live under the condition of water stress. The sub-saharan African region has the maximum number of water stressed regions. Water scarcity and water pollution have affected every continent of this world and now is the biggest challenge for the people to overcome it.

Below are the main reasons of water pollution in Asian countries like India:

First massive industrialization and growth throughout the country; due to the increase in the upcoming social change all the manufacturing wastes are discharged into the water bodies. Which results in the addition of toxins in the water bodies which are harmful for the people. The urban population continue doing their regular work unknowingly. Animals’ bathing in the same water makes it disease prone. Second, sewage add chemical (cancer causing agents) and other pathogens cause disease; dangerous chemicals cause harm hence making it useless. We need to pay more attention in taking care of the disposal of such deadly carrying agents. Third, industrial accidents like the oil spill in the Gulf of Mexico; in the world’s history the largest marine accident is in the Gulf of Mexico where the oil spilled into the water making it deadly and dangerous. Fourth, nuclear accidents adding radio active waste. e.g. Fukushima Nuclear accident; Fukushima Daichi accident occurred during the earthquake which led to the water toxicity by the mixture of all nuclear wastage and material in the water bodies. Fifth, deforestation; due to deforestation there is lack of rain which leads to the full water levels, with no recycling of water. So the water which was there before will be the same however polluted and unused.

Prevention of Water Pollution:

A climate report from the UN states that the Himalayas are the only source of most of Asia’s biggest rivers like Indus, Ganges, Yangtze, Brahmaputra, Salween, Mekong and Yellow and these are being polluted day by day and leading to much toxicity of water and if this thing continues all the people will lose there lives and there will not be a life there.

It’s the individual’s responsibility for taking care of the environment especially regarding the water pollution as this is the main factor. Below are some of the points:

First, never throw any trash here and there; you always need to drop it in correct trash bins so that it does not get disposed into the water bodies by the rain water. Second, use water wisely. Never keep the tap open unnecessarily when not using the flush in an appropriate way. Third, do not throw any of the toxic chemicals or disinfectants into the sink or toilet because that is connected to the nearby water bodies where all the things get accumulated and finally leads to the water toxicity. Fourth, purchase more environmentally safe and hygienic liquids for homes and public places. Fifth, if we live nearby water bodies then we should plant more and more trees in order to avoid direct disposal of chemical or pesticides of our garden into water bodies. Sixth, factories should try to recycle their wastage or should think of better ways of disposal rather than draining waste it out to rivers. Seventh, storage of rain water can play a major role in saving the earth from water scarcity. Constructing tanks and reservoirs with a design that can help in storing pure rain water is absolutely necessary.

Some other steps are also taken by local organizations in India. Several nonprofit organizations are working in this respect. The “Ganga Bachao” movement is an example of these initiatives. (Agarwal, 2005)

History of clocks

The time is very important nowadays for our life, and if we will go back for the history of clocks and how people know about them and when they use them you will be surprised about the valuable information.

Originaly, the sun was the main thing to show the time by putting a vertical stick in the ground. The sun was moving from rising until sunset so the shadow of the stick was showing the line on the ground and the people were know the time. So the shadow of the stick was stopping in twelve steps from sun rising until sunset and by people’s calculation they divided the day in to two parts then they discovered the time.

The Egyptians improved on the stick shadow and they were the first people who used the sundial from about 800 BC. But they had some difficulty to measure the time by the sun because of the weather changes in the season.

Then the British were putting the sand in a bottle of glass with a small space to move the sand from the first bottle to the second bottle as they had difficulty because of the weather.

How have clocks changed over the years?

Between 1629 and 1695 Christian Huygens was the first person who developed the pendulum-driven clock. Then people tried to improve it up to the beginning of the 18^th century when John Harrison started to improve the first pendulum clock. He used two different metals to build a pendulum as the best metals were bronze and steel. The two metals responded differently to cold and heat and thereby overcame the negative effect of heat and cold on the pendulum's length that resulted in the clock either loosing or gaining time.

Over time some people tried to improve the clocks by inventing the hand clocks; Abraham Louis Breguet put the formula to invent the first clock after the improvement at the beginning of the 19^thcentury.

The production of clocks began in the United States after the American War of Independence and made it possible for most families to pay for the clock. The electric clock was an American innovation of the early 20^th century invented by Henry E. Warren and was followed by the quartz clock invention in 1929.

Present time

Nowadays, the clocks are very important for all the people in the world to know the timing for the days. Christian Huygens was the first person was developed the pendulum-driven clock in the 17^thcentury. After that a lot of changes happened to improve and develop the watches.

By today there are more than a hundred companies who are trying to develop the clocks by doing a lot of designs and colors. Before people had the clocks in their homes then the men were wearing pocket watches and it was very famous in America. Then they changed the way by wearing the watches on their wrists and the target people were men, women and the children.

Over time, the companies made a lot of different changes in the watches to attract people by adding a lot of features including the dates and digital numbers. Also they are changing the sizes for the watches to be smaller and lighter.

reflection

We have started our semester on 10^th of February 2013. Mr. Hedley Butterfield was our teacher and I am going to write a reflection about our course from beginning up to date.

In this semester we have known a lot about Mr. Hedley like: his life as a teacher and as father/grandfather, which kind of assessments we will have in this course, how to create blogs and he also teaches us how to write a summary.

When Mr. Hedley started to give us some passages to write a summary I didn’t like it because one of my weaknesses is reading. But day by day I was trying to improve my reading skills by reading some newspapers and trying to do summaries. Then Mr. Hedley gave us some practice about how to write a summery. Then we began to do some summaries and we made three summaries as well. We wrote about the desert horsemen, car accidents and pearls in the Arabian Gulf.

In my conclusion, I would like to thank you Mr. Hedley because I really learned how to write a summary after some practice which you gave us as I was weak on that. And thank you for giving me some techniques about the main points to write any summary.

In the 20^th century the Arabian Gulf was the largest diving economy. Pearling boats in the 1950s were commonplace. However, EMEG and Jumairah group have jointly formed a new pearl diving eco tour in waters off Palm Jebel Ali.

The pearl tradition in the UAE will not be forgotten even if it has gone. Swaidi invited reporters from Gulf news on a pearling dive to a secluded protected cove where the media learned about pearl diving.

The oyster hunters aren’t rich and the dhow outing was about the journey. The Arabian dhow was made of wood and it was the length of it about 60 feet. Before a lot of people were searching for the pearls but nowadays the number of people has decreased to be much less.

Long ago people went sealing and looking for the pink pearl as it is hard to find it. People were saying “from each 100 oysters maybe you can find only one pearl”.

Now, in one of the biggest hotels in Dubai they are doing a diving for pearls as an activity to attract the tourists and if anyone found a pearl he can keep it as a souvenir.

According to Dubai Health Authority the traffic accidents are the lead cause of death 14 years and younger.  And it is the major problem in the UAE because a lot of people are never use a seat belt.
 
Souad Al Merri believes that all the authorities should make an effort to give the advice to the people to use the seat belt. And she believes that 96% of children are not seated properly in there seats.
 
Nowadays, they create car seats for the children to be relaxing in their seats. Research from Philadelphia found that booster seats reduce the risk of injury for children from four years to seven years by 59% compared to seat belts.
 
Some people are believing that people are not using car seats for the children because they are crying and the children are not comfortable with the seats.
 
The RTA has taken the action for the importance of child safety in the vehicles and to teach the parents about safe habits. In the past ten years 2,134 people have been killed and 23,082 injured in traffic accident in Dubai alone.

A group of horsemen in Al Awafi desert start searching for the troublemakers who have taken refuge in the desert. They are part of RAK police patrol division and each emirate has a horses division to monitor there areas. L Col AL Amerri said " there role is to be our eyes on the desert and the villages". The horse men were every day doing there to protect any suspicios people.

Unfortunately, sometime people want to bother and distract the horsemen. One of the more popular getaways is al Awafi desert. LtCol AL Amerri said that "we are very protective of our horses" as they are well trained and they are calm.
