The Problem with Water Contamination - 1451 Words

Water contamination is said to be the leading cause for diseases and deaths worldwide. Dirty water is the world’s biggest health risk. Over 1 billion people worldwide lack access to safe drinking water. 5,000 people die each day due to dirty drinking water. Water pollution may be analyzed through several broad categories of methods: physical, chemical and biological. Many people don’t have the luxury of being able to grab a bottle of water whenever they want because there is so much pollution and chemicals in there water system. When water from rain and melting snow runs off roofs and roads into our rivers, it picks up toxic chemicals, dirt, trash and disease-carrying organisms along the way. Increased water pollution creates breeding grounds for malaria-carrying mosquitoes, killing 1.2 million to 2.7 million people a year. Water Pollution and contamination is responsible for 40% of the world’s population resulting in death each year. Hydraulic fracturing, or â €Å"fracking†, is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside. Approximately 40,000 gallons of chemicals are used per fracturing. Up to 600 chemicals are used for Fracking. Methane concentrations are 17x higher in drinking-water wells near fracturing sites than in normal wells. There have been over 1,000 documented cases of water contamination next to areas of gas drilling as well as cases of sensory, respiratory, andShow MoreRelatedThe Prevention of Water Contamination: Mission Impossible?1503 Words   |  7 PagesWater is one of the most vital components of human life.

Business Tourism and Supply Management

Question: Describe about the Business Tourism and Supply Management. Answer: What tools or strategies would you need to use to find the following information? Computer training needs of staff Under this objective, information on what needs to be covered during the training can be obtained from the job description manual. This document can be obtained from the human resources department. The job description manual will inform you on the specific tasks that the employees are required to carry out during the course of their duty and will require computer training. Under each identified task, specific learning objectives can be developed through IT books with same or similar topics or searched online via IT Educational journals like Elsevier. The specific learning objectives can also be developed by interviewing vocational tutors in ITteaching institutions on the computer training needs of staff. (Burke, 2011) A simple survey can also be conducted among the members of the staff to gauge the level of their computer knowledge. This will reveal what computer knowledge gab exist among members of staff thus developing learning objectives or instructions based on the outcome of the survey. If the training was meant to achieve basic computer literacy among the staffs then a simple survey like tasting MS office skills will suffice, but if the objective was to achieve a technical computer literacy then a more robust survey will be required like installing the technical software and asking employees to perform certain basic functions using the same software. (Burke, 2011) Staff absence rates for the last two years This information can be obtained from staff daily sign in records for the past two years. The records will then be counterchecked against list of staffs members expected to be at work at each day or shift of the period under consideration. The rate can then be calculated by dividing the number of employees absent per month by the total number of employees expected to be at work during the month under study. The daily rates or yearly rates can be obtained through the same method. In some organization where the process of signing in for work is automated through biometric systems then a simple request for generation of reports on employee absenteeism through the computer can be done. The reports can be generated on monthly, weekly, yearly or on any other timeframe basis required. (Support staffs have highest sick rates, 2011) General climate information for capital cities in other states This information can easily be obtained through online platforms that reports on weather updates and climatic conditions. The same can also be obtained through a correspondence in the city of interested if you have one there, e.g. a friend, colleague or a family member in the city of interest. This information can also be obtained by turning in to the major TV stations of the country/state where the city of interests is located during prime time news like 1pm or during the hourly news time. During this time weather update of major towns in that state are usually provided and you can pick updates on your city of interest. (Kozak, Uysal and Birkan, 2008) You can do this severally so that you can understand the climate of the area. The same information can also be obtained through weather books by checking the corresponding month or period youd like to know the climate of your city of interest.
