Human Population Growth

The two types of commonwealth product of any species are exponential growth and logistical population growth (Simon, Reece and Dickey, 2010). Exponential population growth is be as the rate of which a population grows constantly over a period of time resultant of continuous birth rate and nonpareil environmental conditions. In other words, the quality and quantity of resources is available at an overall higher standard, (Otherwise, 2012). The second type of population growth is logistic population growth. Most environments do not have unlimited resources. throttle factors such as carrying capableness come into play.Carrying capacity is an environment that have gots a maximum population size (Simon, Reece and Dickey, 2010). When the population size begins to reach carrying capacity, thither is a decrease in growth rate. When the population size is at its maximum for carrying capacity, it yields a zero growth rate (Simon, Reece and Dickey, 2010). As the population grows it can c ause a number of serious problems such as food-scarcity, overcrowding, poverty, increased consumption, excess waste, and exploitation of congenital resources such as land, water, fossil fuels, and vegetation.The combined effects of population growth, consumption, overuse, wastage and misuse of resources will strain the capacity of the earth to sustain life (Simon, Reece and Dickey, 2010). Human population exceeding its natural resources will limit access to basic needs such as adequate housing from overcrowded areas as lack of space will choke evident. Building materials involve resources such as timber from forests which results in deforestation. mover of transport require more consumption of fossil fuels, and then contaminant of air, land and water result from greenhouse gas emissions.Scarcity of food and potable water will incur as more mouths to wipe out require agricultural production, also a result in deforestation, thus the need for increased water usage, and the app lication of pesticides and fertilizers that make the soil unfertilised and water scarce and non-potable. Generation of waste increase will require critical attention to proper waste management in aim to prevent the spread of disease or epidemics (Simon, Reece and Dickey, 2010).Population will establish most rapidly in places least able to handle it, growth nations where hunger, political instability and environmental degradation are already distributive (Otherwise, 2012). Massive efforts are in great need to keep neighborly and economic conditions from deteriorating further. When the number in population exceeds the natural resources available to sustain it, there will be a profound effect on the overall quality of life and the degree of human suffering on Earth.
