Threats of Excessive Population Growth
Excessive population growth can pose the most serious long-term threats to the world. The phenomenon often used to go un-noticed or was less emphasized but, it's a well established fact now that our lives are going to get affected more than ever before if population continues to grow at alarming levels. The current surge in population started from 1700s. Before that, during the early 0.5 million years of human inhabitance on earth, population grew with negligible rates. That changed much as world's annual growth rate rose to 0.5% between 1850 and 1900 and rocketed up to 2.0% during the 1960s (Pimentel). Right now, we are going through a critical phase of population explosion, as in the last 50 or so years, the recorded growth rate is faster than ever before, and probably faster than it will ever get (Prb.org).
Excess of every thing has its fallouts - population is no exception. Researches worry that the increasing growth rate, which has already started to deplete natural resources of earth, would one day threaten millions of people with famine, disease and shortage of vital necessities of life. Major risk that population outbreak pose is the strain it introduces on the fixed supply of natural resources of the planet. Proper functioning of the eco system is at stake as forests get chopped off since population has to grow. In making room for housing, to provide additional wood needed for construction purposes, and for fulfilling the fuel needs, massive deforestation drives could occur - much intense than the current operations and could wipeout the forest lands. Effects of population growth are well observed even now and these factors (ill effects) would certainly grow with the growth in population. World Bank and the U.N. reports that currently there are 1 to 2 billion people devoid of adequate food supplies, i.e. they are malnourished - the largest figure recorded to date, and expected number could rise up to 3 billion...
Excessive Population Growth Threats Associated with Excessive Population Growth The world population has grown more in the past 50 years than it did during 4 million years of previous human existence. It continues to grow at a rapid pace, showing no signs of stabilizing in the near future. If we consider the fact that the earth has a limited amount of space and a finite number of resources, it is logical to
