Human Population Growth
The two typecasts of creation emersion of any species are exponential growing and logistic race result (Simon, Reece and Dickey, 2010). exponential tribe growth is defined as the number of which a population grows everlastingly over a period of snip resultant of continuous birth dictate and ideal milieual conditions. In separate words, the select and quantity of resources is avail competent at an overall higher standard, (Otherwise, 2012). The second type of population growth is logistic population growth. Most environments do not shit un b distinguished resources. Limiting factors much(prenominal) as carrying capacity come into play.Carrying capacity is an environment that sustains a utter closely population size (Simon, Reece and Dickey, 2010). When the population size begins to reach carrying capacity, in that location 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 former a number of serious problems such as food-scarcity, overcrowding, poverty, increased consumption, excess waste, and developing of natural resources such as land, peeing, fossil fuels, and vegetation.The combined effects of population growth, consumption, overuse, wastage and contumely of resources volition strain the capacity of the human beings to sustain life (Simon, Reece and Dickey, 2010). Human population exceeding its natural resources go out limit access to basic gather ups such as adequate housing from overcrowded areas as lack of space will create evident. Building materials require resources such as timber from forests which results in deforestation. Means of revel require more consumption of fossil fuels, thus pollution of air, land and water result from greenhouse gas emissions. meagreness of food and potable water will incur as more mouths to banquet require agricultural production, also a result in def orestation, thus the need for increased water usage, and the application of pesticides and fertilizers that give away the soil infertile and water scarce and non-potable. Generation of waste increase will require critical attention to decent waste management in order to prevent the spread of disease or epidemics (Simon, Reece and Dickey, 2010).Population will rise most rapidly in places least able to handle it, developing nations where hunger, political asymmetry and environmental degradation are already pervasive (Otherwise, 2012). Massive efforts are in great need to keep companionable and economic conditions from deteriorating further. When the number in population exceeds the natural resources available to sustain it, there will be a dark effect on the overall quality of life and the degree of human trauma on Earth.
