1. By definition, population growth refers to the increase in the number of individuals living in a certain location. Basically, resource scarcity often happens quickly as the population increases exponentially. Thus, it leads to specific environmental concerns like global warming, deforestation and biodiversity loss. As of 2020, the world population is more than 7.8 billion people that need to be fed, clothed and kept warm, nurtured and educated. In fact, these people continuously busy consuming resources like land, food, water, air, minerals and fossil fuels as well as producing vast quantities of waste that results to air and water pollution, greenhouse gases and toxic materials. Accordingly, by 2050 the United Nations estimates that the world population will reach 9.2 billion. Moreover, population growth also plays a huge role when it comes to economy and development. Given that there is a fixed quantity of land, population growth will eventually reduce the amount of natural resources that can ultimately result in disease, starvation and war. Indeed, over population has an effect in scarce capital from savings and investment on countries that thereby placing drag on economic development. 2. Throughout history, and particularly during the twentieth century, environmental degradation has been primarily a result of our attempts to obtain improved conditions for growing numbers of people for food, clothing, shelter, comfort, and recreation. The magnitude of the threat to the ecosystem is linked to human population size and resource use per person. Resource use, waste production and environmental degradation are increased by population growth. They are further worsened by consumption habits, certain technological developments, and particular patterns of social organization and resource management. Consequently, scarcity and failure to manage natural resources caused by this phenomena. 3. Abundance, birth rates, death rates, growth rates and age structure are the five key properties of population. Abundance refers to the representation of species in a particular environment. Birth rates and death rates on the other hand pertain to the number of born babies and death in a year per 1000 people. Growth rate is the rate at which the number of individuals in a population increases in a given time period, expressed as a fraction of the initial population. Lastly, age structure is the proportion of a population in different age classes. Generally, these data affects each other as all of them are essential to be able to assess the country’s economic development and environmental resources.

4. The age structure of a population is a major element in population dynamics. By definition, age structure is the proportion of a population at various age groups. Basically, age structure makes it possible to better predict population growth, plus the potential to correlate the growth with the region ’s level of economic development. Generally, age structure is important for economists to identify the composition of people who were still at school, the economically active persons and the dependent ones like the age of 60 above as well as 0-17.

5. Carrying capacity is considered one of the critical factors in maintaining ecological balance and sustainability as it pertains to the maximum number of people or species that the environment can sustain unlimitedly. It likewise incorporates a restriction of resources and contamination levels that can be kept up without encountering significant levels of change. On the off chance that carrying capacity is exceeded, living organisms must adapt to new levels of consumption or find alternative resources. Carrying capacity can be influenced by the population size, utilization of resources, and the degree of pollution and environmental degradation. Carrying capacity, however, need not be fixed and can be expanded through good management and the development of new resource-saving technologies. 6. There are major factors that cause the population to change such as birth rates, death rates and migration. The birth rate is the number of live babies born in a year for every 1000 people in the total population while death rates are the number of people dying per 1000 people. When birth rates are higher than death rates the population of an area will increase. This is known as natural increase. These changes can influence population structure negatively or positively depending on the shift as there might be a possibility of unbalanced age structure among individuals to sustain the economy and environment. 7. Yes, there is a need to restrict population growth. Population growth directly triggers higher demand for provision of various aspects of human existence including food, healthcare, jobs, housing, infrastructure, access to resources and many other issues. Without population control, a blast will take place and as a consequence, access to the basic needs of human existence will be much more difficult to obtain. Economic growth will be affected if population growth goes unchecked....
