As technology is ubiquitous it has made learning more collaborative and inclusive which has helped teachers and students work in tandem to achieve their goals. Educators spend a lot of time evaluating and grading the student but with the introduction of Artificial Intelligence there has been a depreciation of about 7% in the expenditure of time thus also helping the educators to update the learning contents systematically.  Recently Singapore, Japan and United Kingdom has adopted Artificial Intelligence Classes for students.  Artificial Intelligence also promotes adaptive learning where people from different background as well as people with various cognitive and intellectual disability / capacity can work together in an integrated environment.  

 Likewise a coin has two sides, AI has its pros and cons; due to its great development in the field of education it has put schools, discipline and sense of obedience, reverence and punctuality in jeopardy.  And moreover it is bizarre and implausible to computerize all facilities. 

Artificial Intelligence has also helped students to learn any time anywhere conveniently at their own pace. It promotes self-motivational and self-paced learning. In addition to this AI also helps students to be lucid and pragmatic.  AI also permits a person to foray a various fields enabling the person to acquire a whole gamut of experience and thus making a person more reliable and resourceful.

 As children are the future leaders, the very essence of a nation’s progress; it is imperative to make the right choice — Artificial Intelligence

Today, I would like to take your attention to a key problem we face, which is plastic.
There is a famous quote .It is only ‘just one small straw,” said eight billion people. Yes.. its a fact that 8 Billion plastic straws are used and thrown into our environment every year. The total production of plastic and other solid waste is around three million tons per day. This is  approximately ten times the amount we produced  a century ago. India generates close to 26,000 tonnes of plastic a day, and tragic part is , almost two third part of this remain uncollected. The presence of plastic possess an array of problems to our environment. When plastic accumulates in an area it will begin to negatively impact the natural environment and create problems for plants, wildlife, and even the human population. Often this includes killing plant life and posing dangers to local animals both in land and sea.

Plastic is undoubtedly a very useful material, but it is also made from toxic compounds known to cause illness, and because it is meant for durability, it is not biodegradable. Plastics and their by products are making our cities look like garbage bins, getting dumped into oceans and waterways, in huge quantities ,contributing to health problems in humans and animals.

Let us know turn our attention towards solution to this issue. The key steps to  address this issue are
1. Reduce the use of Plastic
2. Reuse Plastic
3. Recycle Plastics
And off course finally to invent plastic alternative substances or environmental friendly plastic substances.

Let me present a simple and practical solution to this issue which as students we all can easily take part . My idea is  a proposal to my school principal based on the principle of reduction, reuse and recycle. The idea is to implement a Green Ambassador program in our school and link it with the students’ performance card. The program will be based on the principle of Reduction, reusing and recycling of plastic. Every student will be given a card which will be evaluated every month and points will be awarded to students who demonstrates or produces the following results
1. Preparing plastic awareness posters and displaying in class rooms- 5 points
2. Submission of plastic Waste data every month- 5 points
3. Evidence of plastic reuse like paper bags used in grocery, old bottles used as plant pots etc.- 10 points
4. Evidence for monthly reduction of plastic waste- 5 points

Based on their accumulated points, the highest boy and girl from each class may be awarded the green ambassador badge. Annual progress card should have this entry for Green Ambassador program and all academic
I believe that such a Program which is linked to academic progress card can influence students and their families and create awareness about plastic. IF this program us successful in our school, the same program can be implemented in other schools also and so together the student community can achieve a lot against plastic waste.

I believe that  bringing awareness about plastic among the society and a building  can make a lot of changes. Let us start this from our self  by making a commitment today that we will start reducing the use of plastic

Thank you

ABSTRACT

Sustainable development aims at the sustainability of the natural resources for today’s generation and continues to meet the needs of future generations. The worldwide fascinated field of interest is the sustainability of domestic water. How to meet the future challenges?

In Arid region like Kuwait, the fresh water resources are limited and mostly dependent on sea water by desalination techniques. Excessive with drawl of water from the aquifers is prodigious either for industrial, domestic and agriculture purpose. As well the global impact is more that, no adequate rainfall to recharge the aquifers. If this continues, the future consequence on the limited water resources is going to have a great effect in the country.

Also enormous quantity of water is being wasted from the household after a single use. Keeping this in mind, there is a new way of approach to reuse the Grey Water by simple scientific principle of Filtration and Disinfection and to use for watering the lawns, car wash, firefighting, flushing toilets, and irrigation purpose. The treated Grey Water may be utilized for recharging the aquifers by artificial means. The aim of this project was Grey Water collection from the selected areas of Kuwait, treatment and analysis of the proposed study.

Keywords: Grey Water, Aquifer, Filtration, Disinfection

I           INTRODUCTION

Shrinking of natural water resources, increase of population and modern life style demands the usage of Grey Water in Kuwait. Reuse of treated Grey water may reduce the consumption of fresh water in future and may be conserved for future generations. The production of fresh water is more expensive than treated Grey Water. Literature survey of A. Abusam,^[1]Rawa Al-Jarallah,^[2]   Jasem M^[3]  and Ahmed Ibrahim Abd Alaziz ^[4]relates more closely the wise use of Grey Water, as there is an increasing demand of domestic water. The rate of consumption of water in Kuwait is more for car washings, cleaning of utensils when compared to laundry and shower. Kuwait Government had started “Tarsheed Project” to create the awareness to public about the importance and need for conservation of water. From 2009 different research studies were conducted for the consumption of domestic water and also specified the need of Grey Water use but not collected for the quality testing. Though, Grey Water has been used in many countries even without any treatment and growing different variety of plants yet Kuwait has not started using the Grey Water till today. Also the public has a fear in their minds that the Grey Water without treatment will affect their health conditions especially in the middle east. This made them not to use the Grey Water. Keeping in view and reviewing the data from the available literature, the present study involves reuse and recycling of the Grey Water by simple, easy and effective treatment and experimentation was carried out in the laboratory for the quality determination of Grey Water.

Grey Water is the water collected from kitchen sink, shower and washing machine. But the quality of different waste streams will be variable, depending on the types of cleaning products used and they may have an impact. The water characteristics that may affect include suspended solids (SS), nutrients, Biological Oxygen Demand (BOD), and microorganisms. Based on the parameters the grey water was treated. The preferred treatment for the Grey Water was slow sand filtration and disinfection using bleaching powder as a disinfectant.

II         OBJECTIVES

• Efficient use of grey water using cost effective treatment.
• To check the plant growth and its edibility.
• To use the treated Grey Water for recharging the Aquifers.

III        HYPOTHESIS

Despite of the global climatic changes, using treated Grey Water may sustain the water for next generations.

IV        STATEMENT AND RELEVANCE

The purpose of this study was to illustrate the utilization of Grey Water in arid areas like Kuwait for the sustainability of water resources in future.

V         SCIENTIFIC CONCEPTS AND PRINCIPLES RELATED TO THE PROJECT

• Slow Sand Filtration- The set up consists of different layers used for the filtration of Grey Water.
• Disinfection- Filtered water was disinfected using bleaching powder.
• Analysis- Physical, Chemical and Microbiological analysis was done to check the quality of the water to meet the specifications for irrigation.

 VI        METHODOLOGY

Grey Water Treatment

• Materials & Chemicals Used:

Used Plastic bottles, Glass bottles, Cotton, Activated Charcoal, Fine sand, Coarse sand, Small Gravel, Big Gravel, Tea Strainer and Bleaching Powder.

• Grey Water Collection:

The sources of grey water are water from kitchen, shower and washing machine collected separately, blended and transferred into a clean glass bottle.

• Grey Water sampling:

The sampling was carried out for three days continuously at Fahaheel, Salmiya and Farwaniya areas of few houses selected randomly.

• Filtration Process:
• A filtration system was set up to filter the grey water in each residence.
• The filtration arrangement (bottom to top) is as follows:
• Cotton- Acts as a slow porous filter
• Activated Charcoal- Removes bacteria, odour and colour
• Fine sand and Coarse sand- Trap Micro-organisms
• Small Gravel and Big Gravel- Extra filtration
• Coffee or tea strainer- To remove floating matter
• Filtration was done by the above set up method.
• Disinfection: The filtered water was disinfected using 0.05g of bleaching powder per one liter of filtered Grey Water.

VII      RESULTS OF CHEMICAL AND MICRO BIOLOGICAL ANALYSIS

All the samples were collected from the areas of Fahaheel, Salmiya and Farwaniya and analyzed for the following parameters with the support of third party laboratory. The results were tabulated in the respective tabular forms and the data was evaluated.

Table:1 Physical&Chemical Analysis of Grey Water

Table:2 Metal Analysis of Grey Water

Table:3 Micro Biological Analysis of Grey Water

As per the results of physical &chemical, metal and microbiological analysis tabulated, most of the parameters were in the range of KEPA specifications. The analysis results were different for the three areas because the Grey Water Collected was entirely based on the type of detergents, soaps and dish washing liquid used. On the average of the three selected areas results, the treated Grey Water contains appreciable levels. The graphical representations of the few parameters are as follows.

The graphical representation results of the Physical &Chemical parameters, Nutrients- phosphate, nitrate and potassium reflects the use of treated Grey Water for irrigation purpose. Initially plantation was done using the treated Grey Water by planting gram seeds for a week during the month of July which had grown well. (Figure 6)

Figure 6 Green Gram Plant

Next the plant growth was verified for two chili plants a week, using normal water and treated Grey Water. There is an equal increase in the height of the plants irrespective of the water used. (Figure 7&8)

Figure 7 & 8 Comparison of Chili plant height using Normal and treated Grey Water

(The leaves represent tomato plant and not chili)

The edibility of the plant was not tested but based on the analysis results of metals and nutrients gives a clear picture that plant is edible. Even though, micro biological parameters of the analysis are high which may not lead to threat for crops.

IX        CONCLUSIONS

In general, Municipal wastewater treatment plants in Kuwait use sand filtration and chlorination and to an advanced level ultra-filtration (UF) and reverse osmosis (RO) for the production of domestic water. The present study on reuse and recycle of Grey Water using sand filtration and disinfection is more easy, rapid, effective and economical when compared to the fresh water production. Hence the treated Grey Water can be used for watering the lawns, cleaning of cars, firefighting and flushing toilets etc. By the graphical representation of the results the samples meet the KEPA specification criteria indicating that Grey Water may be used for the irrigation like drip or sprayed irrigation in Kuwait .Grey water may also be used for subsurface irrigation of ornamental plants like jute, fruit trees like mango, orange etc and best suitable for mature saplings like paddy which have considerable tolerance to salinity, sodium compounds, and high pH levels.

 X         SOLUTION TO THE PROBLEM

According to statistical data collected from the literature, ^[1] the rate of water consumption in Kuwait per day is more than one million cubic meter on average. So, there is a demand of water at present and in near future. To meet the future challenges of sustainable water resources in Kuwait, the best way is practicing the recycled Grey Water for normal domestic usage like watering the lawns, cleaning of cars, flushing of toilets, firefighting and for irrigation to reduce the fresh water production.

XI        FUTURE STUDIES

• In near future, to study about the use of different types of charcoal materials like wood charcoal, coconut shell charcoal etc for further reduction cost of treated Grey Water.
• Comparison studies of the Aquifer water quality in terms of chemical & microbiological analysis and treated Grey Water testing from different areas of Kuwait.
• Studies on recharge of the Aquifer using treated Grey Water by small scale filtration pit set up in the residential areas of Kuwait.

Advantages:
We come to know about current affairs, news going all around in the world. Children also get entertain by watching cartoons, stories that provide you moral values and lessons. You can also watch food recipes and try them at home. You can watch movies, listen to songs, watch daily soaps, horror series etc.

Disadvantages:
If there are advantages of watching television, there are disadvantages too. Watching television in excess can affect our health that is it affects our eyes, makes lazy like couch potatoes etc. Television also makes a lot of sounds which affect our minds. Many TV shows are not suitable for innocent children. We compromise are sleep when addicted to television. We sometimes get negatively inspired by our favorite actors, actresses.

Technology has its own advantages.

Lot of development have been made in the field of communication and networking. Facetime and google video call is no longer new to us. Bots are everywhere. IPhone seri as voice assistant, Amazon Echo as call assistant, Microsoft Cortana as meeting assistant…what not!!!Sandy Robot is a robot invented in India, by a company in Pune. My parents were even planning to get one at home.Robotic surgery is already in its pace. Many progresses have been made in the field of agriculture and biotechnology.

As we rise in this world, sometimes I worry whether we are in right path or not?

Today, everyone is busy and have no time for people around. Everyone is hooked to their phone. Children prefer video games and phone games rather than traditional family games like Scrabble, Ludo etc. Many kids get deviated with online chatting and gaming. Lack of physical work is causing health issues in adults.

Anyway to summarize: Anything in excess is poison. Hence, let us wait and watch!!

From the late 1950’s , efforts were made to develop rockets which were powerful enough to make satellites, robotic spacecraft or spacecraft carrying humans to either to circle the earth or proceed towards other worlds of our solar system. On October 4, 1957, the Soviets launched the first artificial satellite, Sputnik 1, into space. Four years later on April 12, 1961, Russian Lt. Yuri Gagarin became the first human to orbit Earth in Vostok 1. On July 20, 1969, NASA created history by sending Astronaut Neil Armstrong to the moon. Six Apollo missions were made to explore the moon between 1969 and 1972. Today unmanned missions has reached almost every planets in our Solar System. The world is now preparing to send humans to Mars. We also have a permanent Space station, The International Space Stations where humans permanatly stationed at space through out the year.

Besides satisfying the human urge to explore space, devices launched into space by humans have made our lives here on earth easier and safer. Thus, benefits offered by space exploration are truly revolutionary. Today space technology benefits almost every one directly or indirectly. The world is better connected today because of advanced satellite communication systems. We are better prepared to natural disasters like Tsunami,Hurricanes because of weather prediction from advanced space Imaging technologies. Our farmers are benefitted from weather prediction and mapping of resources. Experiments conducted in space results in advancing research in the fields of engineering, technology, medicine, and many more .More important, human space exploration symbolizes our passion, excitement, commitment and courage and motivates billions across the world.
