Four Global Issues
Table of Contents
The Four global issues chosen were virus attack, malaria, digital dive and water scarcity. These 4 global issues have something in common which is that they are increasing affecting the world nowadays. Virus attack was chosen for the reason to inform the readers how the prevention could be done since people are not familiar with the solution or avoidance. Malaria was chosen since it has been a big case in the world for the perfect vaccine to cure the disease is not found yet and to write about how serious it is especially in Africa. Water scarcity was chosen to write and inform the readers on how important this issue is to the global economy and lastly digital divide was chosen to explain to the readers on how the poor country is compared to the rich people. The purpose of the research was to explain with accurate information. This report will discuss the reasons of how these 4 global issues are caused and its effect. In the last part solutions will be provided on how these issues could be avoided.

Computer virus is a malware program or an undesirable code when executed, duplicates by inserting copies of it into data files, hard drives and other computer parts. It is said that virus often performs an inimical activity corrupting data files, stealing files and the ability to control one’s gadgets (Brian). The causes of virus attack are through the use of internet, removable storage device, and E-mail. Internet is the fastest and the easiest way that virus can spread due to links that automatically downloads virus such as clicking advertisement in a webpage. Followed by E-mails such as SPAM mails and devices such as USB and hard drive can carry virus which was originated from different computer which were infected through virus (Brian). One of the most common and deadliest viruses is Trojan, Spyware and Worms. Because of these viruses multiplying or entering electronic gadgets, the virus immediately seeks for other host that can be infected. Once the virus spread into the device, they transfer controls to the application program they tainted giving the ability of the virus creator to steal or files and the capability of destroying the computer. Virus attack currently cause billions of dollars’ worth of economic damage each year due to wasting computer resources, data corruption, increasing od maintenance cost and causing system failure (Bell). The first virus attacking incident happened in the late 1970s when it infected ARPANET which is a large network used by Defence Department (Beal).
Water scarcity also called water crisis is the lack of sufficient water available to meet the wants of water usage within the country. The earth is covered up with 70% water and the freshwater makes up a very small portion which is only 2.5% of the total amount of water available (“Fresh Water Crisis”). Water scarcity can be a result of two mechanisms, physical and economic water scarcity. Physical water scarcity is due to the uncontrolled natural water supply to peoples demand such as overpopulation, climate change and other natural calamities where in economic water scarcity is the outcome of poor management of the sufficient water available to the people such as the factories polluting the biodiversity and people wasting or over using the water. Water scarcity may give negative effect to the community (WWF). When fresh water is not available to the people, they get disease from drinking contaminated water and in fact, 3.1 million people die each year from water related disease. Lack of fresh water also means less water to plant the crops causing the food supply to decrease that result to constant huger. Water scarcity can cause poverty for the clean water decreases and the price or the value has also increased which can lead people to poverty (National Geographic). Example of a countries suffering from water scarcity is mostly from the Africa. It was not due to physical but because of the economic water scarcity which could not follow up the needs to the people. If no actions are implemented, in 2025 the fresh water will decrease 1% which will be greatly affect the nation worldwide (“National Geographics”).
Malaria is an infectious disease for human and other animals caused by parasitic protozoans called Plasmodium and is transmitted through particular mosquito which is the Anopheles mosquito (Mangan). Female Anopheles mosquito is simply the only mosquito that transmits malaria. Specific time is given when the mosquito is particularly active which is 9pm and 5am. The cause of malaria is simply when someone is staying outside where mosquitos are present and usually tourist people are common to get the disease for they stay outside for too long and is commonly found in Africa. Malaria infections are identified by paroxysms or recurrent attack that develop into a three stage. The first stage is the development of chills plus headache. In stage 2, the infected person’s skin may become hot and dry while having a fever. As the temperature drops, stage 3 begins by feeling extreme fatigue and weak while sweating. Within 10 to 15 days, these symptoms are generally spotted. There are some serious cases when infected person will not get a treatment, it can lead to death for the reason that the bones in the body system will weaken. It was also found that cerebral malaria could occur if the blood vessels in the brain are blocked with the infected blood cells. As a result it can lead to swelling of the brain and brain damage. In worst case, after getting bitten by the mosquito, death may strike in a couple of hours. In a survey, it was stated that people die every minute because of being infected by malaria (“Malaria Q&A”).
Digital divide is a social and economic issue referring to the opposite amount of information between those who have access to the internet. It is also used to describe the discrepancy between people who do not have the resources and access to the technology (Beal). Digital divide also describes the people those who have the knowledge, abilities and skills from those living in rural and urban areas between educated and uneducated. The main cause of digital divide was due to the gap of developing countries and developed countries. The rich countries which had the power to adapt the new technologies has become more developed while the poor countries having inefficient money had a failure in purchasing the technologies which had pushed the chance of development of the countries itself. Other cause could be the education system. For the successful society, they mainly focus on the education making students becoming the future developers of the countries while developing countries not giving that much importance for the educational system lack the skills to create students who could change the society (Rapaport). Because of the digital divide bring the gap between the rich and the poor, which leads discrimination. The poor countries would not be able to follow up the rich country in the near future. Competition could not be attempted for the lack of facilities the poor countries have and the developed country would mind only to their development leading to imbalance to the world economy. In addition, the country that lacks with technologies lacks the knowledge to teach the usage of the technology making the country not developed. It would be hard for the poor countries to enter the global market and when foreign investors comes to the developing countries, the tariffs are lowered which free trade will be done. However, this method can help the rich countries richer which means to say that there are possible advantages of digital divide (James).
To sum up, the 4 global issues have been discussed and were explained with the information gathered from the internet such as journal, journal articles, statistics and other webpages.
Computer virus is commonly used for hackers to get personal files. However there might be several ways on how a virus can attack a gadget but there are also several ways a person could avoid virus attack. The best solution for virus attack is to download a virus killing system which could detect viruses before entering to any parts of the computer. In addition, people should be extra careful and should have the knowledge whether they should enter a certain website and when using a USB, the user should always remember to scan before activating and should safety remove the USB.
Water scarcity has been a problem to the nation and fresh water is decreasing. Physical and economical water scarcities are done and when this continues there would be insufficient fresh water for people. The best solution that could reduce the scarcity of water is by protecting the available wetland (WWF). By protecting the wetland it can lead to less pollution to the biodiversity and can let the people know the importance of water. In addition, in the future scientist must find a ways
Methods used to prevent malaria are when sleeping, people should use mosquito nets which prevents mosquitoes to enter the place where the people are sleeping. Currently there is no vaccine for malaria to be cured 100% but some medications are believed to prevent mosquitos to bite such as putting anti mosquito lotion on the skin when going out door. This depends on how one individual take care of them.
Despite there are some advantages, the disadvantages outweighs the possible advantages. The gap will continue none unless the government in the poor country invest money to the development of their own country. There are possible global solutions which could be done. Number one is economic equality. For instance, many work related tasks are done online, and completion of the work may not be done due to the lack of access of internet to work up with the company standard. And the government should invest more on the educational system to create workers of the country.
