Overpopulation is an undesirable condition in which the number of the existing human population exceeds the carrying capacity of the Earth. This scenario can be illustrated in cases such as, for example, a square foot can normally accommodate about 7 people, but due to the "overcrowding" factor, the square feet have been crowded by 3 to 5 times the normal number of people . Overcrowding and overpopulation can be considered synonymous. Crowding has been defined as an increase in the intensity of competition for space (John J. Christian Sc.D, 1963). As Riley E. Dunlap said in 2016, "Environmental problems were recognized as such in the 1960s, and Earth Day of 1970 in the United States and the United Nations Conference on the Human Environment of 1972 transformed “environmental quality” into a major social problem. problem both nationally and internationally. Until today, the problem of overpopulation was a major problem on a global scale and humanity was united and eager to solve this problem, or at least reduce it. Say no to plagiarism.

Get an original essay According to William Ryerson's 2015 descriptions of overpopulation, “Human numbers and activity are already destroying the ecological integrity of the planet, trampling on myriad others. species.' The percentage of built development increased linearly with the number of human growth – more humans means more development, so more and more ecosystems are destroyed to make way for human development activity. Howard Alper and Mohammed HA Hassan, 2012, stated that “unsustainable consumption patterns affect the Earth's ability to support its natural biodiversity.” They also stated that “source consumption patterns in high-income countries are gradually destroying natural sources.” These consumption patterns in these statements did not only refer to foods, but also to the environment of this Earth, as we can see today many deforestations have occurred, especially in advanced countries that want to expand their development. Overpopulation was caused by excessive human growth. Population and growing demand for products and services make humanity's thirst for fossils completely unstable. (William Ryerson, 2015). As fossil resources continued to deplete over time, we struggled to survive. According to a study by Ann Hoevel in 2008, "if the population continues to grow at the estimated rate, such rapid growth in India by mid-century could lead to overpopulation and an uncertain future for the environment and people who live there. Rapid growth is clearly a major factor that has caused overpopulation. Apart from this, “industrialization and the resulting rapid population growth and concentration are the major contributors to environmental problems in both developed and developing countries” (Azuka A. Dike, 1985). It was true that industries and developments were necessary, but these plans were supposed to be carefully executed to minimize environmental damage. For a better understanding, we consider the effects of overpopulation on a global scale, for example, according to William Ryerson, 2015 stated that “nearly a billion people go to bed hungry every night. This was devastated because it meant that a seventh of the human population on Earth slept every day, hungry, wondering if there would befood or not the next day. William also predicted that "water demand is expected to exceed supply by 40 percent over the next 20 years." This would happen because in the future more humans need their water supply to support their daily lives, thus making water one of the supplies we need to be competitive, forcing on the other hand families or poor people to live with a lack of water. Overpopulation also affects the agricultural domain because "the increased intensity of management of the agricultural domain is one of the main causes of the decline of local species wealth. (Frederick Hendrickx, 2007)'. This article will discuss the problems caused by overpopulation and ways to overcome these problems. This paper will also focus on 3 main issues such as world hunger, water shortage and global agricultural demand. According to the Scottish Government publication (2005), the activity must be effectively controlled and planned, which includes handling arrangements for human, animal and livestock. animal feed, agricultural fuel, dirty water, fertilizers, veterinary drugs, chemicals and pesticides on your farm. The land that has been used must be taken care of by the farmer because it is one of his sources to keep them and others alive. They need to be more responsible towards their important source of life so that it can bring them more benefits. This is because farmers seem not to take care of the land they use as something important. They tend to neglect the land by not managing the crop calendar effectively. The planning included the management of fertilizers, dirty water and others. Thus, the farmer is the person closest to the land and knows best how to manage the effects of using chemicals or fertilizers that can have a detrimental effect on the land. Apart from this, according to Townsend, Mangi and Austin (2006), "planting perennial crops instead of annual crops in highly sensitive areas, for example, would retain nitrogen in the soil and significantly reduce groundwater loss ". The farmer's priority is to prevent nutrients rich in nitrogen and phosphorus from flowing into water sources near fields and livestock farms. Nitrogen can be circulated in the atmosphere in 3 ways: biological, human and chemical or physical. Nitrogen cycling chemically or physically can occur when humans convert nitrogen into fertilizer. Fertilizer used to help the plant grow as quickly as possible by increasing the nutrients in the plant. But this can be a problem when there is too much fertilizer, which is known to limit nutrients, which can trigger the algae boom. This is because when algae continues to float on top of the spot or pool, it can block sunlight from passing through. When this happens, the ecosystem of the place will reduce and affect other organisms that live in the place. So as a responsible person we need to know the amount of nitrogen or fertilizer so that we can reduce the problem caused by excessive use of fertilizer or the nitrogen content which can increase the number of algae which will affect the other component. in the same ecosystem. Next, we need to increase nutrient management. According to the United States Environmental Protection Agency (2017), applying the right amount of fertilizer, at the right time and using the right method, can reduce pollution. So, as a farmer, we, as a good person with great human value, must take care of the land either to use it as a source offood, or as a place where we have to stay at a given time. We need to reduce pollution that can make land unusable. The farmer can also take the course which teaches students how to take care of the farm. They can increase their knowledge and use it to make land use more efficient. In this new era of globalization, water and energy are important resources for economic and demographic growth and yet both are increasingly scarce (Carillo and Frei, 2009). Every living thing needs water to stay alive. As population growth continues, water has been limited to meet user demand. However, this source is one of the renewable resources. The user must use it as effectively to make it accessible to everyone. We can reuse water as a way to use it efficiently. Water recycling can be defined as the reuse of treated water for other beneficial uses such as industrial, agricultural and other processes (Water Reuse,2018). In the industrial sector, water is one of the important elements for its proper functioning. Indeed, water can be used in several ways, such as to cool the machine, to wash the product, etc. For this process, we can reduce the use of clean water by reusing the treated water so that the clean water can be used by something else. For agriculture, using treated water is much better than clean water. Indeed, it can bring many benefits to health, the environment and the economy. One of the benefits of using this type of water is to reduce pressure on fresh water sources (Jaramillo and Restrepo, 2017). The agricultural section uses most of the available water, which in total represents a water consumption of around 70% and treated water can be an alternative. in order to save the use of clean water. Another advantage of using treated water is reducing the costs of extracting groundwater resources. The technologies that must be used to extract drinking water are numerous and involve many authorities to manage this project. This will also lead to high costs of building and maintaining the technology. This project may also have a detrimental effect: we will explore more land and cut down more trees. This will cause the green plant to diminish and have another harmful effect on the world. For the whole world to have a good effect, use treated water as much as possible to reduce the problem of lack of clean water. Apart from this, as we move forward into the millennium era, we have been involved in high-tech production to make a better world. Then there are technologies that will be used to achieve desalination. Desalination is a process that removes salt and other minerals to create fresh, drinkable water. This process always involves seawater. According to Khawaji, Khutubkhanah and Wie (2008), "a seawater desalination process separates salty seawater into two streams: a freshwater stream containing a low concentration of dissolved salts and a flow of concentrated brine.” This technology is developed for the ship which sails in the sea for a long time and lacks clean water. Generally, these technologies are suitable for remote locations from land where clean water is limited, such as oil rigs, ships and others. We can also use this technology on land to reduce clean water consumption. They can place the technology near the sea, pump the sea water as much as possible and convert it into clean water. It's the same concept: they use wave energyfrom the sea to convert it into another energy that we can use such as electrical energy, because wave energy is part of renewable energies. Finally, the product of water treatment can be useful if we use it to the fullest because its use has many health, environmental and economic benefits. According to the United Nations (2010), around 884 million people worldwide, especially in countries like Mozambique, walk more than a kilometer to get to the water source and use less than 5 liters of water unsanitary every day. This poor and unsanitary water makes it difficult, especially for children. In Senegal alone, half of schools had no water and no sanitation facilities, causing dehydration and an inability to concentrate for students. In a water-rich country, water consumption is 210 liters per capita per day in Malaysia, which is 27% higher than the water consumption recommended by the World Health Organization (WHO), which does not is only 165 liters per capita per day (Jye, 2017). Effective water regulation and policy is an important part of protecting health. A systematic survey of community drinking water system facilities which should cover water sources, transportation infrastructure, treatment plants, storage tanks and distribution systems. Microbial contamination can threaten public health. Thus, water suppliers must boil water or take other measures before distributing it to communities. It is important that water suppliers take full responsibility for the quality and safety of the water produced at all times, Guidelines for Drinking Water Quality, (nd), 2006, p.8 -9. Regulations can solve water shortage problems. Aspects that require special attention, such as water reuse, water resource management, water rights, industrial water use, wetland restoration, water supply domestic, water pollution, etc. Water management has the capacity to respond to human interventions and various natural resource-related events and long-term water policy decisions on the environment and economy. Water management can only have an effect on the environment and the economy in the long term (Madaan, 2016). Extensive water management has been associated with insufficient plumbing systems in public and private buildings. Millions of liters of water are lost each year due to leaks and sewer contamination, creating water shortages. These problems are caused by poor design, incorrect installation, modifications and poor maintenance (Madaan, 2016). A poor plumbing system can lead to huge wastage of water. For example, if pipes carrying clean water are made from unsuitable materials, this can lead to bacterial growth. Leaks in pipes and sewage systems also lead to water contamination. To achieve a good plumbing system, pipes should be leak-proof, durable, of a smooth, clean interior and protected against anticipated stresses and connections between clean water supplies and wastewater disposal systems should not not occur, Guidelines for Drinking Water Quality. , (nd), 2006, p.17. Water conservation is one of the main ways to solve the water shortage problem. Water conservation is the practice of using water efficiently to reduce unnecessary water consumption. Water is a vital element for all life onearth, from trees to animals to humans, especially fresh, clean water. To avoid wasting water, you must first be aware of the amount of water you use. Therefore, to succeed in water conservation, each individual must be responsible for their water consumption. There are many ways to save water, such as not letting the water run while brushing your teeth, soaping or shampooing. Collecting rainwater can be beneficial for outdoor uses such as gardening and washing cars. Even using low flush toilets for urinals can save up to 30% water when using the toilet (Jye, 2017). Overpopulation will also lead to increased competitiveness for the resource, which will also lead to increased crime rates. Countries with an overpopulation problem usually have a high crime rate compared to countries with a balanced population because when all basic necessities are provided, there is no reason to commit crimes. Education not only provides the individual with knowledge, but also makes him or her more patient (Becker, 1997). Individuals with quality education are wiser in decision-making, they will be able to predict what the consequences of their criminal activities will be on those around them and on themselves (Hjalmarsson, 2012). Currently, India is the second most populous country in the world. after China, but it is expected to overtake China by 2022, where the growth rate will naturally expand. This is happening because of China's most controversial policy in its modern history, namely the "one-child policy", introduced since 1979 and recently replaced by the "two Chiles policy" in 2015. This " one-child policy” “help control and gradually reduce the population. It is estimated that around 400 million births have been avoided thanks to this policy according to the Chinese government (Gordon, 2016). Birth control is a long-term plan that will take decades to see results, but it is the fastest and most effective way to control and limit the population. Finally, the common problem related to overpopulation is hunger. This can be proven by the rapid population growth of the East Side which brought inevitable famine there. This statement can be supported by “There is no point in blaming climate change, food shortages or political corruption. Sorry to be neo-Malthusian about this, but continued population growth in this region makes periodic famine inevitable” (Porrit, 2011). These problems are due to lack of food, lack of drinking water, land invasion and others. The growth rate which has increased throughout the year is one of the causes of this problem. When the population already exceeds food sources, hunger will increase. This problem can lead to an increase in the number of deaths. To solve this problem, we can use clean meat to meet the growing global demand for protein. Clean meat known as lab-grown meat, which is meat grown in cell culture rather than in an animal body (Cassiday, 2018). It is also one of the technologies that have been developed to support human capabilities this year. These measures aim to meet protein requirements, which leads to the problem of hunger. This activity has certain benefits, including sustainability, environment, animal welfare and food safety. According to a report by the Food and Agriculture Organization of the United States (FAO), global consumption of.
