Published: mon, 5 dec 2016 the world has been experiencing a rapid increase in human population for the past 10, 000 years according to the most recent un statistics, population has grown from several millions back in the bc to over 66 billion in the 21st century. The main motive was not environmental: rather, population growth was seen as retarding economic growth and fomenting political instability, making countries more susceptible to communist influence. Continued world population growth tends to exacerbate both localized and global environmental problems that will demand serious policy responses in the coming century despite growing recognition that population is one among several key factors in environmental problems, its role remains controversial. Population growth has had a negative impact on the quality of the environment as more land is used for agriculture or living purposes, the environment changes drastically as the population of humans grows in certain cities or rural areas, more resources must be used to maintain the well-being of the population. Although the global rate of human population growth peaked around 1963, the number of people living on earth — and sharing finite resources like water and food — has grown by more than two-thirds since then, topping out at over seven and a half billion today, and human population is expected to exceed nine billion by 2050.
The population growth of any animal, if left uncontrolled can become burdensome farmers have noted, for many centuries, what the effects of an uncontrolled predator population can do to livestock once their natural prey run out, or are harder to find, the predators may turn to domesticated animals, despite the risks. Population, natural resources, and environment clearly there is a relationship between population growth and environmental asia than in any other region of the world the fastest growth will be in asia’s developing countries energy use in the developed countries of the world is. “continuing world population growth through mid-century seems nearly certain,” university of california, berkeley, demographer ronald lee noted recently in science “but nearly all population forecasts implicitly assume that population growth will occur in a neutral zone without negative economic or environmental feedback. Since the time of the bubonic plague in the 1400’s, the growth of population has been on a constant increase between the time of the plague and the 21st century, there was been hundreds and thousands of wars, natural calamities and man-made hazards however, none of these have made a dent on the population.
In biology or human geography, population growth is the increase in the number of individuals in a population global human population growth amounts to around 83 million annually, or 11% per year the global population has grown from 1 billion in 1800 to 7616 billion in 2018 it is expected to keep growing, and estimates have put the total population at 86 billion by mid-2030, 98 billion. In 1963, the us national academy of sciences published the growth of world population , a report that reflected scientific concern about the consequences of global population growth, which was then reaching its peak annual rate of two percent. Mostly ignored in the environmental debates about population and consumption is that nearly all the world’s nations agreed to an altogether different approach to the problem of growth 15 years. Slower population growth and renewable resources slower population growth, in some cases nationally and in others globally, is likely to lead to a reduced rate of degradation of renewable common- property resources such as air, water, and species of plants and animals.
Tldr (too long didn't read) population growth is the increase in the number of people living in a particular area since populations can grow exponentially, resource depletion can occur rapidly, leading to specific environmental concerns such as global warming, deforestation and decreasing biodiversity.

According to the worldwatch institute, a nonprofit environmental think tank, the overriding challenges facing our global civilization are to curtail climate change and slow population growth. Impact=technology+ affulence +population impact on population growth: industrialization, burning fossils fuels, non renewal resources, pollution, increased co2 level.
The environment on earth is suffering from the growth of global population the depletion of resources and biodiversity, the production of waste, and the destroying of natural habitat are serious. Human population growth and climate change the largest single threat to the ecology and biodiversity of the planet in the decades to come will be global climate disruption due to the buildup of human-generated greenhouse gases in the atmosphere. The medium variant of the united nations' population projections indicates that africa will account for nearly half of global population growth between 2010 and 2050 more than doubling the total population on the continent however, other regions and other stresses on both the supply and demand side of water also contribute to growing scarcity. To assess the complex interdependencies between population growth, economic and technological development, and the associated relative scarcities of land and water, we use the global biomass optimization model (globiom.
The influence of population growth in pressures exerted on s ome aspects of the global environment, suspected that population dynamics influence econ omic growth, employment and. Population size and growth tend to expand and accelerate these human impacts on the environment what is more concern, the number of population rise will increase to such an extent in future that it will cause overall scarcity for resources. But, when it increases by a fixed percentage it is known as exponential growth eg 10, 102, 103, 104, or 2, 4, 8, 16, 32 etc population growth takes place exponentially and that explains the dramatic increase in global population in the past 150 years.
