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 the case where, for example, one square meter can normally accommodate around 7 people, but due to the "overpopulation" factor, the square meters have been congested with 3 to 5 times the normal number of people. Crowding 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 stated by Riley E. Dunlap in 2016, “environmental problems were recognized as such in the 1960s, and the 1970 Earth Day in the United States and the 1972 United Nations Conference on the Human Environment transformed “environmental quality ” into an important social factor. problem both nationally and internationally." Till now the problem of overpopulation has been a serious global problem and humanity is 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 descriptions of overpopulation in 2015, "Human numbers and activities are already destroying the ecological integrity of the planet by trampling on myriads of other species.' The percentage of built development has been increased linearly relative to 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, in 2012, stated that "the pattern of unsustainable consumption affects the earth's ability to sustain its natural biodiversity". They further stated that "the source consumption pattern in high-income countries is gradually destroying natural sources." The consumption patterns contained in these statements do not only refer to foods, but also to the environment of this Earth, as we can now observe a lot of deforestation has occurred, especially in advanced countries that want to expand their development. Overpopulation was caused by excessive human expansion. The population and the growing demand for products and services make humanity's hunger for fossils absolutely unstable. (William Ryerson, 2015) . As fossil resources continue to deplete over time, we are struggling to maintain the basis of our lives. According to research conducted by Ann Hoevel in 2008, "if the population continues to grow at the estimated rate, such rapid growth in India between now and mid-century could lead to overpopulation and an uncertain future for the environment and the people who they live there." Rapid growth is clearly a huge factor that has caused overpopulation. In addition to this, “industrialization and the resulting rapid population growth and concentration are major factors contributing to environmental problems in both developed and developing countries” (Azuka A. Dike, 1985). It was true that industries and developments were necessary, however these plans were supposedly carefully executed so as to minimize environmental damage. For a better understanding, let's consider for example the effects of overpopulation on a global scale, according to William Ryerson, who in 2015 stated that "nearly a billion people go to bed hungry every night". This was devastating as it meant that 1/7 of human population on Earth slept every day starving, wondering whether or not there would be food the next day William also predicted that “the demand for water is expected to exceedthe offer of 40% within the next twenty years”. This would happen because in the future more and more human beings will need water supply to support their daily lives, thus making water one of the resources we need to compete, forcing on the one hand poor families or people to live with the lack of water. Overpopulation also affects the agricultural sector as the increased management intensity of the agricultural sector 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 them. This paper will also focus on 3 major issues such as global hunger, water scarcity and global agricultural demand. According to the Scottish Government publication (2005), the activity must be controlled and planned effectively, including the management of human livestock, feed animals, agricultural fuel oil, dirty water, fertilisers, veterinary medicines, 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 it alive and others. They need to be more responsible towards their important source of life so that it can provide more benefits. This is because it seems that farmers do not take care of the land they used as something important. They tend to neglect the land by not managing the cropping program effectively. The program included management of fertilizer, dirty water and more. Therefore, the farmer is the person closest to the land and who knows best how to manage the effect of the use of chemicals or fertilizers that can give negative effects to the land. Beyond that, according to Townsend, Mangi, and Austin (2006), “planting perennial crops instead of annuals 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 ending up in water sources near fields and livestock. Nitrogen can be recycled into the atmosphere in 3 ways: biological, human and chemical or physical. The chemical or physical nitrogen cycle can occur when humans turn nitrogen into fertilizer. The fertilizer used to make the plant grow faster as it increases the nutrient in the plant. But the problem can occur when there is too much fertilizer, known as a limiting nutrient, and this can trigger an algae boom. This is because when algae continues to float on top of the place or pool, it can block sunlight from passing through. When this happens, the ecosystem of the place will reduce and affect the other organisms living in the place. So, as responsible people, we must know the amount of nitrogen or fertilizer so that we can reduce the problem caused by excessive use of fertilizers or 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 State Environmental Protection Agency (2017), applying the right amount of fertilizer, at the right time, and with the right method can reduce pollution. So, in addition to farmers, we, good people with high human value, must take care of the land both for using it as a source of food and for the place where we must stay at some point. We must reduce pollution that can cause land to become unusable. The farmer can also take the class that teaches students how to take care of the farm. They can increase their knowledge and use it to make the land more effective to use. In the new eraof 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 exceed user demand. Yet this source is one of the renewable resources. The user must use it in the most efficient way to make it available to everyone. We can reuse water as one of the ways 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 industry, water is one of the important things to keep it running. This is because water can be used in many ways, such as to cool the car, to wash the product and more. 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. This is because it can bring many benefits to health, the environment and the economy. One of the advantages of using this type of water is to reduce pressure on freshwater sources (Jaramillo and Restrepo, 2017). The agricultural section uses most of the available water, totaling about 70% of water consumption and treated water can be an alternative to save the use of clean water. Another advantage of using treated water is the reduction in costs of extracting groundwater resources. The technologies to be used to extract clean water are high and involve many authorities in the management of this project. This will also lead to high costs of building and maintaining the technology. This project may also have negative effects, that is, we will explore more land and cut down more trees. This will cause the green plant to decrease and give another negative effect to the world. To make the whole world have good results, use treated water as much as possible to reduce the problem of lack of clean water. Besides that, as we move into the millennial era, we have been involved in producing high technology to make world better. Then, there are technologies that will be used to carry out 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 salt water into two streams: a freshwater stream containing a low concentration of dissolved salts and a concentrated brine stream.” This technology is developed for the ship that has been sailing for a long time in seas that have little clean water. In general, these technologies are suitable for places far from land that have limited clean water 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 and pump as much seawater as possible and convert it into clean water. This is the same concept that uses sea wave energy to convert it into another energy that we can use as electrical energy because wave energy is one of the renewable energy. Finally, the water treatment product can be useful if we use it to the fullest because many benefits are obtained from its use in terms of health, environment and economy. According to the United Nations (2010), approximately 884 million people around the world, particularly in countries like Mozambique, walk more than 1 kilometer to the water source andthey use less than 5 liters of unsafe water every day. This poor and dirty water makes life difficult especially for children, in Senegal alone, half of the schools had no water or sanitation facilities and caused dehydration and inability of students to concentrate. In a water-rich country, water consumption is 210 liters per capita per day in Malaysia, which is 27% more than the World Health Organization (WHO) recommended water consumption of just 165 liters per day. understood per day (Jye, 2017). effective water regulation and policy represent an important component for health protection. A systematic survey of community facilities in the aspect of drinking water system which should cover water sources, transmission infrastructure, treatment plants, storage tanks and distribution systems. Microbial contamination can put public health at risk. Therefore, water suppliers should boil water or take other measures before distributing it to communities. It is important that water suppliers take full responsibility at all times for the quality and safety of produced water, Drinking Water Quality Guidelines, (nd), 2006, p.8-9. Regulations can solve water scarcity problems. Aspects requiring attention such as water reuse, water resource management, water rights, industrial water use, wetland restoration, domestic water supply, water pollution and others. Water management has the capacity to address human interventions and various natural events in relation to resources and long-term water policy decisions on the environment and economy. Water management can only be considered to have long-term effects on the environment and economy (Madaan, 2016). Significant water management has been associated with insufficient plumbing systems within public and private buildings. Every year, millions of gallons of water are lost due to sewer leaks and contamination, creating water shortages. These problems are caused by poor design, incorrect installation, alterations and poor maintenance (Madaan, 2016). A bad plumbing system can lead to huge waste of water, for example, if the pipes carrying clean water are made of inappropriate materials, it can cause bacterial growth. Leaks in pipes and sewer systems also lead to water contamination. To achieve a good plumbing system, the pipes must be watertight, durable, with smooth and clean interiors and protected from expected stresses and that there are no connections between the clean water supply and wastewater removal systems, Guidelines for drinking water quality, (nd), 2006, p.17. Water conservation is one of the main ways to solve the problem of water scarcity. Water conservation is the practice of using water efficiently to reduce unnecessary water use. Water is a vital element for all life on earth, from trees to animals to humans, especially fresh, clean water. To avoid wasting water, you must first be aware of how much water you use. Therefore, to ensure successful water conservation, each individual must be responsible for their own water use. There are many ways to save water, such as not letting the water run while brushing your teeth, soaping up or shampooing. Rainwater harvesting can be useful for outdoor uses such as gardening and car washing. In fact, the use of low-flush toilets for urinals can save up to 30% of water whenuses the toilet (Jye, 2017). Overpopulation will also cause an increase in competitiveness for the resource which will also lead to growth in crime rates. Countries with overpopulation problems usually have a high crime rate compared to countries with a balanced population, this is because when all the basic necessities are provided there is no reason for 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 their surroundings and 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 develop naturally. 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 with the "Two Chiles Policy" in 2015. This "One Child Policy" they help control and gradually reduce the population. It is estimated that, according to the Chinese government, approximately 400 million births have been prevented by this policy (Gordon, 2016). Birth control is a long-term plan that will take decades to see results, but this is the quickest and most effective way to control and limit the population. Finally, a common problem related to overpopulation is hunger. This can be demonstrated by the rapid population growth on the East Side which caused an inevitable famine. This statement can be supported by 'It's not okay to blame climate change, food shortages or political corruption. Sorry to be neo-Malthusian about this, but continued population growth in this region makes periodic famines inevitable" (Porrit, 2011). These problems are caused by lack of food, lack of clean water, land encroachment and more. The growth rate that has increased over the year is one of the causes of this problem. When the population has already outgrown food sources, there will be more people who will go hungry. This problem can lead to an increase in the number of deaths. To solve this problem, we can use clean meat to solve the growing global demand for protein. Clean meat known as lab-grown, which is meat grown in cell culture rather than in an animal's body (Cassiday, 2018). This is also one of the technologies that have been developed to support human capacity during this year. These steps serve to satisfy the demand for protein that leads to the problem of hunger. There are some benefits of carrying out this activity which include sustainability, environment, animal welfare and food safety. According to the Food and Agriculture Organization of the United States (FAO) report, global meat consumption will increase by up to 73%. Aside from that, one solution would be to include plant-based proteins or insects for the human diet in the sub. Proteins are the necessary source of the human body. It is to gain energy and stay healthy. Proteins are important because to repair the muscle or skin, these proteins help in recovering from the injury in a short time. It is also used for the production of hormones, enzymes and immune functions. Transgenic crops are the future of food. Water is the main issue in agricultural production, 70% of global freshwater is used in crops, so it is important to develop higher performing crops. Traditional approaches to cultivation are.
